i am wonder why nobody ask about a LHG XL60 antenna
So, a 2,5km link would be easily possible

there is a CRS328 4C 20S 4S+ comming later.

Gesendet von meinem HTC Flyer P510e mit Tapatalk 2

Which ROS version do you use?
Have you upgraded Routerboard firmware?

I suggest a reset everytime after you have upgraded the Board until the AC driver is stable.

sonny

I suggest to reset-configuration on both wireless interfaces and start with default config.
Then you can play arround.

sonny

try HT MCS 12 or HT MCS 13 with auto tdma on ROS 6.19 (6.25) with wireless fp package.
signalstrength should not be worse than -70 (all in range 60-70)

sonny

Mikrotik, now it´s time to get the GPS sync working!
When?
How?

sonny

Which version are you running on your CCR1009?

Gesendet von meinem HTC Flyer P510e mit Tapatalk 2

sonny

At this stage mostly a client has a defectiv wireless card.
Check each client separatly with hughe traffic to identify the bad client.
For a intermediate solution until you can change the client board, increase tdma period size.

Also check if the chains H/V matches on all devices

sonny

Uldis,

when will we see AP sync support for NV2?
Now it is realy time to have this feature.

sonny

RB133 is not supported on ROS 6.xx.
Also this board is EOL since years.

try to reset both devices and start over again.
or
reset both wireless interfiaces and configure new.

are you going to bridge two networks or route from one to another network?

sonny

As I saw TCP throughput becomes better with MCS5
go to MCS4 or even MCS3.
If it becomes bettter, you have big interference at your used frequency.

sonny

Hi Lupin,
have you done a spectral scan at AP side?
What throughput have you masured to the nearest station?

sonny

nobody knows what you mean.
Please explain more what you trying to do.

sonny

set tdma to 2 or 3
reduce TX power until the client get´s rx -68-70 per chain
may be your channel is not interference free.
You should get 38-42 mbit/s

sonny

this might be a MTU issue.
check from the client computers what maxium MTU size you can send over the link.
then adjust yout PPOE MTU size accordingly

sonny

@rodolfo

take a CCR 10XX and connect all EOIP tunnels theere.
Put them in a bridge then add more ethernet ports to that bridge.
On that ethernet ports you can connect BRAS systems, they will loadbalance for you automatically.
The faster one takes the pppoe session.

sonny

We are sorry!
Live streaming because of right problem in Germany not possible

sonny

make shure to use fixed same TDMA settings on all hops. Have a configuration like this Station <-> (AP + AP) <-> (Station + Station) <-> (AP+AP) etc. use minimal power settings. Use only modulatoin rates wehre you archieve 95-100% CCQ Try different frequency like 10--20mhz above or below. Good luck!

sonny

You can use 5-10 CCR´s and use them to load balance the sessions. It will work

sonny

From which version ROS? you have upgraded to 6.22?

in my opinion, dont touch a running system.
It sounds you are statisfied with your setup.
If your CPU will be constantly at 50-60% then think about some new hardware.

you have to use "all rates fixed" on these boards

This issue has been solved with ROS 6.2/6.3 on AP and client.

You will choose A/N mode and set all three chains in HT.
if look at registration table you can see under signal at each client chain0 / chain1 / chain2 - rx and tx values

i would really appriciate sync betwenn AP´s.
It will bring more throughput and higher density of APs on towers with less interference.

by the way for three sectored tower, like wirelsrudys implementation

, you can use ubnt SR-71A with 3x3 Mimo.

Check rojterboard firmware and upgrade if possible.

hi,

does anbody know if there is an ethernet bypass card, which is working with Mikrotik ROS 5.X on X86 PC?

thanks fo any answer.

Set AP in bridge mode -put WLAN and Ethernet in a bridge. Set Cpe1 + Cpe 2 to stationbridge -put WLAN and Ethernet in a bride. Set Cpe 3 in AP mode and bridge WLAN and Ethernet. Try on all links nstreme or nv2. Set different frequencies on both links. If you us N-Standard set advanced datarates. Enj...

We have installtions with WDS and some using Stationbridge mode. We switched to NV2 on 5 sectors 6-8 weeks ago. Now all on ROS 5.6 - it is really stable 20 days up with no disconnction. But the Network is slower than in Nstreme mode. In NV2 mode all connections feel to be viscous and not as fast as ...

now is Summer

we will see how does it performs in Winter.
Gerneraly ther is enough space arround the antenna for ice and snow.
I tihnk it will be better as the antenna without cover.
Because snow and ice will directly cover the antenna.

sonny

you can use this reflector http://cn24.net/SXT-Shield-50.jpg then your SXT is safe . No rain will come into the holes.
Contact me by Email . We ship anywhere worldwide.

sonny

Turn your SXT 90 degree and you will get adequate signal strength.

Hi mahnet,
please contact me out of board for further question and availability about Restless Powerbox.

Hello mahnet,

you can use the Restless Powerbox as power supply with full control off your devices.
it is even a UPS with it integrated batteries.

sonny

Impressed with shielding waveguide around the SXT however i would reduce the size further if the interference is co-location source(s) like other AP's or Ptp on a mast this to have reduced windloading in exposed windy locations, also cannot tell from picture if aluminium is flexible in the center i...

Hi, is qour tx ccq higher then rx ccq? -> then try to shield your antenna against neighbours, or separae it al least 1m from each other. try to change channel and watch CCQs at the neighbour AP´s. if you ar using a SXT try SXT RF shield form DCpower - it removes surrounded RF noise from your SXT by ...

Hi,

what mangle rules do you have added?
can you share?

sonny

Configure RSTP at your switches.
You can avoid Loops in your network

sonny

Hi, I suggest to rotate the units by 90°. So you will not produce RF at the horizontal layer. by the way - I dont like the SXT design, because of it´s reversed antenna polarization and the most worst thing ist the rear cover cap. You cannot use a prefabricated patchcable - the plug with plastic is t...

Hi why dont try a Restlesspowerbox? You will love it, by its multiple features. And its from only 189 Euro. You do not need second powesupply, because if the powersupply will fail the integrated batteries will power the router. you will be informed about a failure by email and/or SMS (optional). Giv...

sonny

this is the best card you can get.
But all Compex WLM200NX and WLM200N5-XXXX should work with mikrotik software and superchannel.
try it by your own, with any card you can get.

Mostly in this situation the radio at AP is damaged. Cannot hear or send properly.
Check if rx and tx signal is rather unequal.

Hi, we have such config working. 2 RB411 in separate Metal enclosure and compex wlm5423a cards. It is vorging Not the Best but o.k. Tx-power should Be Set to minimum. They are Running in nstreme mode. On each pol 8 -10 clients connected, aggregated throughput on each pol is arround 16-20MBit/s. Sonny

Why do Not use Restlesspowerbox ? Www.restlesspowerbox.COM
You can do Monitoring and many other cool things!

this card has a txpower offset like UBNTs XR5. For your card I dont kown how much it is, but eg. for the WLM200N5-24 Compex told me this: "Mikrotik firmware does not compensate for the 4 dBm difference therefore the displayed power in Mikrotik OS is 4 dBm less than the actual power of the WLM20...

cpu load is very high yes, it is a core router two nstreme interfaces and ip load from ethernet. cconnection tracking off, now queues. Only simple routing - customers internet traffic a RB1000 is standby, but when to switch....... around 1000 customers complaining a single minute outtime..............

take bigger antenna, is always better.
Because receive gain is better.

@chadd I will try the settings 8 to 10 the next days on two APs 12 clients and 35 clients. then reporting here the results here. with 2 or 4 as tdma-period-size I got stable latency from AP to clients about 20-30ms. with 8 it increases latency to 40ms but stable @mikrotik Any profund knowledge to NV...

sonny

Thanks, ste for your reply.
I tried varius configurations but had no luck on PtMP.

in my opinion TDMA size is to small to achieve high throughput in PtMp.

Nobody uses NV2 in PTMP?
This is a real world traffic AP 12900 connections 12 APS connedted to sector

after switching form NV2 to nstreme (sunday 21.00h)

any comments?

try to lock datarates at up to 36MBit both sides

then signal fluctuating ist not as much - hoppfully it will be better.
