Sxt LTE 4g+ Cat6>

igorcastelli · Mon Nov 04, 2019 5:17 pm

Hi I have a sxt lte and lhg lte and I would like to upgrade the internal modem. I wish I could do CA (carrier aggregation) for more speed and 4g+. Which modem should I buy so that everything works? Anyone has experience?
Thanks
Igor

The modem inside the Audience LTE6?

Now waiting for Mikrotik to sell the modem separately.

SiB · Wed Nov 27, 2019 1:26 am

I have got "SXTR rev2 & R11e-LTE6 kit" by 1 day.

SIM are not up/down but a/b.
2CA works. Cell/SectorID lock works for primary band and second one "ca-band" works automatical. This lock is now save inside modem, we not must use modem-init.

It's inside house now. I prepare place outsite at 5m up.
My BTS is 3km at 80m up.

I have 2 LHG LTE6 and I notice when several clients are connected after a certain time aggregation does not work more and there is just one band left? if you disable and enable LTE the band aggregation comes back but not long?
the 2 lhg have the same problem.
I fixed the primary band but the aggregation is always lost after a while.
An idea ?

i noticed my LTE6 modem always connects to just 1 (highest) band at start, but later at download/stress it connects to 2nd. Dont know how exactly CA works, but maybe some BTS drops idle connections to don't hold resources?

LTE works like you say, CA begin only if it needed.

I add some information.
One time I do a table of possible 2xCA in EMEA Band's for EP06 and R11e-LTE6:

opera_BBqucAL3cr.png

Modem Firmware v20 is very often use the ca-band on normal and CellLock situation.
Signal levels we see from a primary band.
Both bands in my testing not give many acceleration speed but for sure connection is more stable.

To monitor change of parameters/signals and own watchdog, I write and still do upgrade-s of my script's.
Example:

winbox_v3.20_64_YMynh5FXFr.png

.
NetWatch witch a Duration counting check every 10s the 1.1.1.1 host and have both Up and Down script's.
UP:
.

do {ip firewall layer7-protocol add name=NetWatchTimeSince comment=[/system resource get uptime] } on-error={};
/local NetWatchDuration ([/system resource get uptime] - [/ip firewall layer7-protocol get [find name=NetWatchTimeSince] comment])
/log warning ("Netwatch: UP | check 1.1.1.1 | OffLine Duration was: ".$NetWatchDuration) 
/ip firewall layer7-protocol set [find name=NetWatchTimeSince] comment=[/system resource get uptime];

.
DOWN:
.

do {ip firewall layer7-protocol add name=NetWatchTimeSince comment=[/system resource get uptime] } on-error={};
/local NetWatchDuration ([/system resource get uptime] - [/ip firewall layer7-protocol get [find name=NetWatchTimeSince] comment])
/log warning ("Netwatch: DOWN | check 1.1.1.1 | OnLine Duration was: ".$NetWatchDuration) 
/ip firewall layer7-protocol set [find name=NetWatchTimeSince] comment=[/system resource get uptime];
/system script run RestoreInternet

.
and of course the RestoreInternet script must have permision for Netwatch.

/system script set RestoreInternet dont-require-permissions=yes

Hi people!
Is there any way to bond ether1 and ether2 interfaces on sxt lte6 to gain internet speeds above 100Mbps?

Hi people!
Is there any way to bond ether1 and ether2 interfaces on sxt lte6 to gain internet speeds above 100Mbps?

SXTR have switch chipset Atheros 8227 means ~197Mbps transfer is possible. Main question if R11e-LTE6 have got USB magistral >100Mb and the Atheros8227 have got to CPU >100Mbps because Qualcomm 9531 have internal switch 100Mb and this can be our bottleneck.

Bonding means you must connect two devices and from this second device receive internet. Like: SXTR + hAP ac2

You must

disable PoE on Ether2

connect via mac address, enable romon.

delete bridge port like ether1,ether2 and bridge itself

create bonding

Add IP + DHCP Server + NAT .... OR Passthrough

I have this setup but no time to drive to BTS and do testing with some ISP.
Please provide speedtest's and bandwitch test.
Good Luck

For this specific device, DL speed is up to 300 mbps but ethernet port can handle only 100 mbit, what's the point in purchasing this device then?

Easy, all person who are not in city who are happy when reach 20/5Mb. For them and me a limit of 100Mb is not problem.
I have R11e-LTE6 with 2xCA and now very good stability of internet connection via two band.
And of course antenna is directly connected to modem, without meters of "low noise" cable.

When I drive to my BTS and have best signal ~600m from BTS then I cannot reach >70Mb then you can see in my ISP and only one BTS even 600m from BTS I cannot reach 100Mb. Even in M11G with external antena I Cannot reach >70Mb then sorry but your theory is false.
I have SXT LTE 3-7, SXTR&R11e-LTE6 and wait for LHGR&R11e-LTE6.
Those device have got a purpose in not only my scenario.

Thank you SiB ! Not sure i understand, where is the RestoreIntenet script ? Is the script restore Carrier aggregation if it lost ? I try to make just a copy/paste on Netwatch but i keep going to loose CA...

You welcome.
.

Not sure i understand, where is the RestoreIntenet script ?

This is script with do stg what if the best for you. For example you can do at*cell=0 or do celllock or maybe at+reset or maybe system reboot - you choose what is the best for you.
You can add # and disable this one line too because if you not have got this script=exaclyName then the down-script of netwatch will fail.
.

If this fix your internet connection then yes. I give you a concept.
.

r11e-lte6 is only modem who remember the cell lock settings. All other devices must be initialized every time when they up. For this ROS have got a parameter like "modem-init=" - this info is in wiki lte.
NetWatch is only check access to internet and in down-script the last line try run external script who can do stg with lte interface.
I don't understand why you loose your settings from CellLock - give more information - or write to support@mikrotik.com

Thank You again SiB, i understand it's your own watchdog with the action you choose.
I never lose the Celllock but I lose CA (LTE CA2) the second band sleeps for a while and never wakes up if I don't do an action like you say "celllock or maybe at + reset or restart the system".
may be i have to make a script every hour like at+reset to wake up CA ?
which action is faster not to cut the internet too long ?

you never lost CA ??
thank you again SiB

dad2312 · Fri Jan 03, 2020 1:03 pm

I also note that I lost 30ms of ping compared to LHG LTE Cat4 (exactly the same configuration in the same place with the same first band)
Do you make the same observation?

Well, on a remote location I can get 150-250 Mbps on my phone. I was looking at Mikrotik LTE hardware but since their ethernet port can't give more than 100 mbps it's no use for me.
Don't get me wrong, 100 Mbps is a big upgrade to the wired connection I can get on remote location (10 mbit DL, 1 mbit UL) but if I can get more than 100 mbps why not

I lose CA (LTE CA2) the second band sleeps for a while

i read somewhere on forums, that CA works on demand only(?)
so, if you make some downloads, speedtest or something, will it never come back?

SiB · Fri Jan 03, 2020 3:13 pm

I also note that I lost 30ms of ping compared to LHG LTE Cat4 (exactly the same configuration in the same place with the same first band)
Do you make the same observation?

What you mean?
SXTR have got example 33ms to 1.1.1.1 but LHGR have 63ms or 3ms ?
30ms difference in ping replay?
Please be sure that you have a newest modem firmware.
The best version of ROS now is 6.45.7 but on 6.46.x are some speaks like "slow wifi, slow network". I not proof but maybe you have different ROS version at both?
That behavior should be checked and send to support@mikrotik.com .
I wait for my new lhgr, currently I have sxtr and old one sxt lte 3-7 but on both the ping's are the same like ~40ms to internet host's, datacenters and 1.1.1.1 and 9.9.9.9 .
.

Thank You again SiB, i understand it's your own watchdog with the action you choose.

One of few what I use.
.

I never lose the Celllock

at R11e-LTE6 who save a celllock setting inside him the upgrade ROS reset me a CellLock setting and I must setup it again.
.

but I lose CA (LTE CA2) the second band sleeps for a while and never wakes up if I don't do an action like you say "celllock or maybe at + reset or restart the system".
you never lost CA ??

I have differ situation because I use a modem fw v22celllock and MikroTik Support Team are connecting to my SXTR sometimes...
But I understand this behavior and have got it like you.
After reboot / at+reset the CA is always existing, often works very well.
After at*cell=2,3,,x,y the CA is only sometimes connected but this is lover then 20% of connection, ca-band can be disconnect and not connect - it's not used often..
After at*cell=0 with disable CellLock the CA is sometimes connected. I think in v22 is less times connected compare to official v20 (v20 is better in this field).
You have the same feeling?
.

may be i have to make a script every hour like at+reset to wake up CA ?

This is that imported? Better is like this... when ca-band not exist for last 5 minuts then do action who repair that.
.

which action is faster not to cut the internet too long ?

The best and fasted will be build-in function in modem firmware - this is job for MikroTik team to fix.
at+reset will be faster then power-reset who is faster then ros reboot.
.

thank you again SiB

I share you a two script's.
1) This is a some watchdog scheduler who monitor if script's is currently running, if not then he run it.
Create a scheduler with interval=1m with this script:

#Script WatchDog for script name:
local ScriptName lteLogger2

local ScriptRuningInstances [:len [system script job find script=$ScriptName]]
if ( $ScriptRuningInstances = 0) do={/system script run $ScriptName};
if ( $ScriptRuningInstances = 1) do={};
if ( $ScriptRuningInstances >= 2) do={system script job remove [find script=$ScriptName]};

.
Create a script with name=lteLogger2 and content:

:local watchItems pin-status,functionality,registration-status,current-cellid,enb-id,sector-id,phy-cellid,access-technology,primary-band,ca-band
:local watchFreq 2s
:local lteInfo
:local prevLteInfo ({})
:while (true) do={
	:do {:set lteInfo [/interface lte info lte1 once as-value]} on-error={}
	:foreach m in=$watchItems do={
		:if (($lteInfo->$m)!=($prevLteInfo->$m)) do={
			:put ($m.": ".($prevLteInfo->$m)." -> ".($lteInfo->$m))
			:log info ($m.": ".($prevLteInfo->$m)." -> ".($lteInfo->$m))
			:set ($prevLteInfo->$m) ($lteInfo->$m)
			}
		}
	:delay $watchFreq
	}

This will help you to monitor change's of parameters from "info lte1" command.
You can do simple modification in first line and just have only ca-band to monitor.

EDIT:
Corrected script line:

:do {:set lteInfo [/interface lte info lte1 once as-value]} on-error {}
:do {:set lteInfo [/interface lte info lte1 once as-value]} on-error={}

I lose CA (LTE CA2) the second band sleeps for a while
i read somewhere on forums, that CA works on demand only(?)

There are two things about CA: serving cell capability and actual performance. If serving cell is CA-capable, it'll broadcast certain SIBs (System Information Blocks) containing identification of secondary cells (eARFCN and PCI) ... and detecting these SIBs makes phone display corresponding pictogram (could be LTE+ or LTE-A or something). At this point phone only listens/communicates to serving cell.

When phone (modem) goes into connected mode (as in: radio resources are dedicated ... as opposed to no radio resources allocated to idle device which is registered to the network), then serving cell will allocate resources on secondary cell(s) and instruct terminal to use them (terminal will also perform measurements on secondary carrier(s) to provide feedback on radio channel quality).
Allocation of resources on secondary cell(s) very much depends on availability of those resources and on feedback provided by terminal (e.g. if serving cell is on B20 and secondary is B7 or B3, then quite likely terminal receives secondary cells shitty- because of higher pathloss on higher bands - and eNodeB may decide against using CA for that particular terminal for that particular petiod of time)

I loose much bandwidh like 20 or 30 Mb/s (with CA i have near 70mb/s). There is 30 to 40 clients who is connected (with QOS at 3mb/s down and 2 up => i have near 30mb/s on upload but CA is don't use with upload...) then loose 20 or 30Mb/s is much and clients feel it.

With LHG LTE cat4 ping is 40ms with LHG LTE cat6 i have 70ms (test make several days) test with mikrotik tools to 8.8.8.8 or 1.1.1.1

LOL. Please give me information what is spedicic modem in this Cat4. like R11e-[LTE | LTE-US | 4G ] and if you can do example from my r11e-lte6:

interface lte at-chat 0 input="at*readver"
  output: *READVER: 
release_version: R11e-LTE6_V022CELLLOCK
release_time: 20191125_13_49
ap_version: rls2476

interface lte at-chat 0 input="at^hver"
  output: ^HVER:"Rev 0000"
OK

.

after reboot or at+reset or at*cell=2.3..... or at*cell=0 i always retrieve CA but not long, some time i loose CA after 30mn or 7h, don't understand why. I loose much bandwidh like 20 or 30 Mb/s (with CA i have near 70mb/s).

I do many many many testing and on my fw:22 I see that

Reboot/ usb power-reset / at+reset -> those tree fix the ca-band - means always after one of them, the ca-band can works.

But if I do:

from 1-3 times disable&enable lte1 interface then ca-band do spoil/crash means not be assigned to current connection anymore.

from second time or more the CellLock then ca-band do spoil/crash means not be assigned to current connection anymore.

from second time or more the Disable CellLock (at*cell=0) then ca-band do spoil/crash means not be assigned to current connection anymore.

This give summary:
The Fast reconnect via celllock enable/disable is possible but it disable ca-band pernament from sencond use. Only first at*cell set a setting with ca-band - all next are without ca-band.
To setup CellLock or disable celllock or do re-enable lte1 I must always do additional reboot / usb power-reset / at+reset to reach ca-band again.

Ca-Band can be flapping etc. but when signal are better then it's have got longer connectivity. One ISP disconnect me ca-band but it's because not generate traffic and after I add some dummy bandwith-test every 10m with limited qos then ca-band is provided constancy. This depend from your ISP policy.

You can monitor this by doing every 1s this command, with enable lte logging and specific print like:

interface lte at-chat 0 input="at+eemginfo\?"
log print follow-only where message~"EEMLTEINTER:|EEMLTEINTRA:"

Play with them, description in google.
.

There is 30 to 40 clients who is connected (with QOS at 3mb/s down and 2 up => i have near 30mb/s on upload but CA is don't use with upload...) then loose 20 or 30Mb/s is much and clients feel it.
unfortanly even at+reset is a bit too long 1mn30s it's too much if i have to do action script every 5mn to execute at+reset

In your place when you work like ISP... then the 2xLTE will be better with MultiWAN policy. Of course $... you can write a script who will be check ca-band and do changes on QoS policy base on PCQ.
I haven't any faster way to do re-connection then at*cell who disable ca-band but do a fast re-connection.
I try many AT Commnand's about LTE topic from many at command papers... .
If I have some new fresh info then I write it here.

Of course, you must have computer or mobile phone and some time.

First is read post on what you answer.
Second is to read a https://wiki.mikrotik.com/wiki/Manual:Interface/LTE
When information in documentation are not work for you then you should search assistant like forum/irc/etc.

CA-BAND works but it depend from your ISP.
At R11e-LTE6 with CellLock remember to do at+reset who bring you ca-band again if your ISP give you it.
Read this topic.
Write more specific question because "i see no improvements" it's opinion, not question.
P.S. I is always from BIG letter.
You search stg like this:

[admin@MikroTik LHG] /interface lte> at-chat 0 input="at^hver"
output: ^HVER: MRVLTD01

after reboot or at+reset or at*cell=2.3..... or at*cell=0 i always retrieve CA but not long, some time i loose CA after 30mn or 7h, don't understand why. I loose much bandwidh like 20 or 30 Mb/s (with CA i have near 70mb/s).
I do many many many testing and on my fw:22 I see that
Reboot/ usb power-reset / at+reset -> those tree fix the ca-band - means always after one of them, the ca-band can works.

i see the same thing

But if I do:
from 1-3 times disable&enable lte1 interface then ca-band do spoil/crash means not be assigned to current connection anymore.

from second time or more the CellLock then ca-band do spoil/crash means not be assigned to current connection anymore.

from second time or more the Disable CellLock (at*cell=0) then ca-band do spoil/crash means not be assigned to current connection anymore.
This give summary:
The Fast reconnect via celllock enable/disable is possible but it disable ca-band pernament from sencond use. Only first at*cell set a setting with ca-band - all next are without ca-band.
To setup CellLock or disable celllock or do re-enable lte1 I must always do additional reboot / usb power-reset / at+reset to reach ca-band again
not for me, i always reach CA-BAND whatever action.

Ca-Band can be flapping etc. but when signal are better then it's have got longer connectivity. One ISP disconnect me ca-band but it's because not generate traffic and after I add some dummy bandwith-test every 10m with limited qos then ca-band is provided constancy. This depend from your ISP policy.
i'm totaly agree

You can monitor this by doing every 1s this command, with enable lte logging and specific print like:
Code: Select all
interface lte at-chat 0 input="at+eemginfo\?"
log print follow-only where message~"EEMLTEINTER:|EEMLTEINTRA:"
Play with them, description in google.

thanks for that
.
There is 30 to 40 clients who is connected (with QOS at 3mb/s down and 2 up => i have near 30mb/s on upload but CA is don't use with upload...) then loose 20 or 30Mb/s is much and clients feel it.
unfortanly even at+reset is a bit too long 1mn30s it's too much if i have to do action script every 5mn to execute at+reset

In your place when you work like ISP... then the 2xLTE will be better with MultiWAN policy. Of course $... you can write a script who will be check ca-band and do changes on QoS policy base on PCQ.
I haven't any faster way to do re-connection then at*cell who disable ca-band but do a fast re-connection.
ok

If I have some new fresh info then I write it here.
thank you SiB

Hello guys, is there any way to disable the Carrier Aggregation on the LTE6 modem?

I think my problem may be that...

Hello guys, is there any way to disable the Carrier Aggregation on the LTE6 modem?

Just connect to only one BAND=x

@SiB

Hello SiB

have you noticed with your LHG LTE6 a loss of Ping speed compared to LTE 4?

SiB · Sat Jan 18, 2020 3:42 pm

dad2312

have you noticed with your LHG LTE6 a loss of Ping speed compared to LTE 4?

Only you say about this at this forum. At other channel like IRC/FB no one say about difference.

Yes, I remember that you write that the same settings / band etc. and differ results of ping response.
Please be sure that eNB and CellID are the same on both device when you doing test ping or do CellLock to be sure.
Next please be sure that FW of MODEM are latest.

r11-lte6 -> v20
r11-lte -> MikroTik_CP_2.160.000_v013
r11-lte-4g -> v9
r11-lte-us -> v16.02.183961
sxt lte 3-7 -> v???

and finally do supout.rif and send both to support@mikrotik.com - I am not a MTK programmer or designer and please ask a vendor itself.

At LTE6 the primary band is for signal and ping response that way I use CellLock on B3 and worse B8 speedtest/ping and that way I always have got good speed. Remember that 2CA is two-directional but primary-band give you all main parameters..

dad2312 · Sun Jan 19, 2020 11:32 am

Thanks SiB

i ask again because it seems you d'ont have receive yet your LHG LTE6 when i ask first time..

i have already test LHT LTE4 and LHG LTE6 with
- same lte band, same cell, same firmware, same emplacement, same config etc.... and i loose speed ping with LHT LTE6.

SiB · Sun Jan 19, 2020 1:33 pm

dad2312

i ask again because it seems you d'ont have receive yet your LHG LTE6 when i ask first time..

I just buy it in Friday and wait for delivery LHGR+R11e-LTE6 and RBM11G and pigtails m50 antenna etc..
I have got currently SXTR+R11e-LTE6 and SXT LTE 3-7.
As you can see - both modem-s are the same: R11e-LTE6 on sxtr and lhgr and I have NOT any r11e-LTE itself to compare ping response.
You can do it and ask vendor. Please send e-mail to support@mikrotik.com and ask them about this. Maybe they give you a sure to do warranty rma or give you a newest modem firmware like me (v22).

When I go to with my sxtr+lte6 to my BTS and from car, after 23:00, 600m from eNB who have antenna at ~75m) I receive that parameters:

explorer_lFGvNelJ4D.png

and I do similar test very neat to other one bts. All ping response at B8/B3 are 30-40ms.
I plan today go with the same test but with other SIM ISP who have additional Band like B3/1/7 and I can test the bonding on sxtr to check if is possible to cross the FE.

dad2312 · Mon Jan 20, 2020 11:48 am

Great Values SiB

Your test answers my question. You don't loose speed ping with your lte6. I don't think there is a difference between SXT lte6 and LHT lte6, so it's probably the relationship between my LHG LTE6 and my antenna relay that makes me lose a bit ping speed

thanks SiB

Bonding question

I have SXTR LTE on roof, and Rb750gr3 in house, want to go over 100mbps between them with 2 interfaces.
I make bonding eth1 and eth2 on no default configuration,on both routers, assign ip adress on bonding interface SXTR 192.168.88.1 and Rb750gr3 192.168.88.2
All ok, ping work, Rb750gr3 see SXTR LTE,
but on winbox cant see SXTR LTE and reach that router for further configuration?? Must again go to roof and reset SXTR LTE configuration, please provide workig script example bonding, dhcp,nat for SXTR. Thanks

SiB · Tue Feb 25, 2020 12:41 am

Andrejm

please provide workig script example bonding, dhcp,nat for SXTR. Thanks

.
I thinks this just work. I always enable RoMon and be sure that mac-telnet works on all interface.
If your RB works with "interface list" then you should add the ether1,ether2,bonding1 into "LAN".
WinBox > Tools > Mac Server > Mac WinBox Server > all > OK.

I cannot currently reset my sxtr into no-default to share configuration but I do that testing with bonding in past.
My near bts is to slow and my ISP give me 80/30Mb on distance 600m - then the FE is not limitation...

Please share your results because I not do next test in short time range with other ISP and other eNB to proof limitation of 100Mb... currently I must think that SXTR has one of both Block Diagram (base on other QCA9531 block diagram)

Option one
mspaint_BxKwea5OxZ.png
Option two
mspaint_2rqXBjJhCw.png

.

I hope you can reach more then 120Mbps-190Mbps in DL by 2CA of 2x@20Mhz band's. Good Luck and give feedback.

PS. I will have some free time in 1.03.2020 and you can write me to my Telegram.

Andrejm · Tue Feb 25, 2020 9:57 pm

I read again carefully this thread and post from user SiB have all i need! Thanks SiB!
I have managed bonding and setup SXTR LTE over RoMon, MAC connection from Rb750gr3, all work perfect now 197Mbps is max ethernet speed but my isp provider do 150 Mbps, still better than 97Mbps, thanks again!!

SiB · Tue Feb 25, 2020 11:50 pm

Andrejm

all work perfect now 197Mbps is max ethernet speed

I understand that you do a Bandwitch test between MT<>MT to receive/transit/both the 197Mbps.
.

but my isp provider do 150 Mbps, still better than 97Mbps, thanks again!!

First person who hit >100Mbps. THANK YOU. I must do again my tests with other BTS and ISP who can have @20+@15Mhz at B3/B1/B7.
Please provide the screenshot of speedtest.net/run and WinBox > LTE > interface lte1 > Cellular tab with parameters you receive. If you want to be incognito you can send it ty my Telegram (signature).

Hello @SiB
Your R11e-LTE6 has some CellLock firmware? (and V022 version)

interface lte at-chat 0 input="at*readver"
output: *READVER:
release_version: R11e-LTE6_V022CELLLOCK
release_time: 20191125_13_49
ap_version: rls2476

.
Output from my modem looks different:

interface lte at-chat lte1 input="AT*READVER"
output: *READVER:
release_version: R11e-LTE6_V020
release_time: 20190830_10_49

.
Can you share information:

what's a difference?

where can we get it?

Is "R11e-LTE6_V022CELLLOCK" stock firmware or do you need to contact support to get it?

SiB · Thu Feb 27, 2020 10:55 am

Larsa

Support only. And then when you have some problem with LTE.

Zone

what's a difference?

Only support.
Diffrence is with better resume signal means better stability too.
Speed's are better added. This is my point of observation.

i'm interest by this config, i have sxt lte + hap ac lite, i make bonding on eth 1 eth 2 on both side. Internet is very instable (i reach it and i loose it) don't know why.

can you show your config ?
@SiB may be ?

HI All,
I have an R11e-LTE6, using Vodafone which I have tested broadcasts on band 1, 7 and 20 however I can not get it to connect to 1 and 7 concurrently. It either connects to 7 and 20 or 1 and 20.

I recently purchased a TP-Link Archer MR600 which is a 4G+ device, slipped the Vodafone sim inside and straight away connected to band 1 and 7, which are the fastest bands and got a whopping 90+mbps.

On the R11e-LTE6 on band 1 and 20 I can get a max of 45 to 50.

If I hard set the bands in Webfig, to 1 and 7 all it connects to is band 1 with the CA band blank.

What am I missing here as at the moment I may as well ditch the Mikrotik due to the TP link providing a superior downstream connection.

really frustrating, I hope someone can assist me.

Kind regards
Michael.

R11e-LTE6 use fast bands like B1/3/7 and beetween them only B3+B7 can do 2CA.
Archer MR600 use LTE SoC Qualcomm MDM9240 (the same is in Telit LM940) who have got B1+B3 and wining by this with MikroTik module.

Thank you. I fix problem with -time after reboot as first DOWN report.

Simple Internet detection by netwatch and log - SiB

Download to your RouterOS:

SimpleInternetDetection.rsc

Install it by:

/import SimpleInternetDetection.rsc

Netwatch script is installed here:
WinBox > Tools > Netwatch > host=1.1.1.1 , Interval=00:10:00 , comment="Simple Internet detection by netwatch and log - SiB"

NetWatch script ping every 10s host like 1.1.1.1 and run down-script or up-script dependence of result.
You can add your own line to run command or other script who fix your Internet connection.
Logs show us a final result.

winbox_v3.30_64_WbebCKB23A.png

You can create manually own netwatch by: WinBox > Tools > Netwatch > add
host=IPv4 of host to ping it, like 1.1.1.1 or 8.8.8.8 or 9.9.9.9
Interval=00:10:00 - every 10 seconds

Up Tab

::local uptime [/system resource get uptime]
