Hello. We have still problems on P2MP links. It is 802.11N with NV2 clients who have ROS 5.9 are most stable then clients with 5.19. Any client when is downgraded to 5.9 - then have good uptime and little disconnect. With 5.18 and 5.19 a lot of problems with disconnect :( Have anybody the same prob...
Hi i have download the v5.20 RC1 and now test it with RB433 ,RB411 ,RB 532, RB511, RB112, RB133c and gues what NV2 works now my uptime on some test sites
the CPE units have benup for 10 Hrs ! that is amazing befor is was 2-10 minutes..
Yes , Thats true, we are now using only the System, Routerboard, wireless and the DHCP pakages. then it works , we even disable the BT test server and SNMP server.
after that we have 4.2 Mb ram left in system memmory.
Inox>> Yes i know to test on a few CPE units first i always do that, But her is the problem, the ones we tested on was working...not fast , but it was working , The scary part is the RB112 cards they go dead if you are unlucky, thats the problem , we will be bringing a few of this broken cards to th...
Hi all Ok, but Mikrotik was delivering the RB133 cards with 3.x on it .... and yes i know the cards are low on CPU and memmory but hey they have to get it to work, But i have now have the cards running with 3.19 for 8 -10 days know with no hassel at all, and we can delivery around 8 Mbits to the cus...
We will now use our tool for puting out scripts on our 200 CPE units that are failing now..
with the above changes. and i hope it will fix the problems.
Stay tuned
//Rickard
Some more findings ... and now we have 4.1 Mb ram for use :-) Now we are using only this packages: 2 system 3.19 5 wireless 3.19 6 routerboard 3.19 7 routeros-mipsle 3.19 10 dhcp 3.19 And we disable folowing services: SNMP www under IP services Logging services Btest server I hope this will fix our ...
Yes we used th Dude 3.1 to uppgrade.... i will be posting the Export if i sucess to export it... we have also updated the Bios on the RB 113c and the RB112 to lates version....

We have upgraded from 2.9.51 to 3.19 on our 200 CPE units and now we are in a living hell!. the CPE is stoping some ports like port 25 and so on the only that are working is port 80 ? and this is happing after 4 days the cpu is on 100% and the only solution is to Reboot , its becoming a Dlink :-( So...
Check the AC adapter if the voltage drops , im using only (now) 48 Volt 7 Amps or 24 volt 12 amps, and i newer have problems with drop outs. you can check if you lower the output from the radio cards ,then it probably not disconect.

Yes i was updating a RB112 that have 3.0 on it to the 3.1 and its now gone so the customer is on the way to pic up a new unit.
So i have to check what gone wrong...this time.

We use Fiber 100Mbits today for 450 customers ,We have a AS:nr with RIPE and we can alocate 8000 Ip nr:s to our BGP router, And we use MT 5 ghz for backbone and 2,4 Ghz for CPE.
Hi Normis, We found the solution with bad trhuput in the VPN conections. It was in the BGP router side. When we removed the MT router and put in a JP2320 then the problem was gone. So it must be related to the BGP . we have 30 Psc of MT routers that are working well now. and the Speed is up again in...
Hi,
We using 2.9.48 today on a P4 2.5 Ghz celeron with 512 Mb ram and we are pusching 50 mbits today with cpu usage 35 %. And we have alot with TOS Marks and Ques enabled.
And we have 450 Users running. Works great!
Hi
The graph looks kind of odd the signal goes from -58 to -45 db ? that a lot for a solid PtP link
Put on Nstream on it, for the ACK and Polling, and the dip you have down to -85 db is strange.
looks like a big inteferens at that time . is it samte time every night ?
In sweden we us this program http://www.tptest.se the TPtest program is the "Standard" for every ISP her. The only thing we do is to put up a own TPtest server, on our network , And its free and it works
If you use the MMCX connector the right setting for that is antenna-mode=ant-b
its like that on the SR5 anyway...the default is for the UFL conector...
Hi i will have a up/down converter ready soon from 5ghz to 10 ghz.
and i have a custom build combiner /diplexer for 4 diffrent transmitters to one antenna! this is for the 5-6 ghz band. the chanel separation is around 26-30 db. so i hope it will work.
Hi ccrum, Intresting about your test with circulators, in a few weeks i will try my new manufactured Combiner for the band 5.4 -5.8 Ghz with 4 input/output to one antenna :-) its a another company that will build this for me . it have 25 db isolation betwen the inputs. and i hope it will work. I don...
Ok Then you have Big problems with the cabels or antennas or the SR5 cards. it totaly impossible to get that low signal that you get . i was checking my link now that are 8 km LOS with r52 at 5ghz and with solid parbolic 25 dbi on both sides the signal now is -49-51 db. and i have 5 m coax on each e...

We have make one utility that can handel unlimeted of host in PHP webpage I can paste in CLI commands to all my CPE units .
to change 300 units takes 1 hour i think.
And it works for all kind of equipment
I need to put out scripts to all my devices like CLI commands .
today i have a Telnet apps that can handel 500 hosts . but have it in the dude will be awsome
Yes you can use a upconverter to a standard 5 ghz card.
I will try this to but for the 10 ghz range .
But i thing you have to built all the gear by your self or check this site they can help you out http://www.procom-dk.com/ they built feeders and parabolics osv..
Today i was testing Beta5 on my RB511 AP-Bridge 2.4 Ghz G only mode and with OSPF enable,with 8 customers on. And i did work great for 20 min then fail, and need reset to come up again, I use Nstream with CDMA Off. The AP was answering pings but no more. This is the same behavior like Beta 3 //Rickard
You can change the firmware in the Turbocell CPE to work wit standard WiFi, I have a lot of the old KN50 CPE , and im trying to put in the CB3 firmware on it so then i can use it anyway .
//Rickard
The speed you get is not Ok im running 10 mile (16KM) links with Nstream ON, and i have 20 -25 Mbits with R532 and that is on GN-WI01HT (R52 equal) radio, with 26 Dbi grids, and the signal is -58- -62 db, And yes ve are running VoIP calls to

We tryed this CSMA/CA backoff option tonight in production :-) it was on a RB532 with 15 users. And it gave us litel improvment but i dont know if u have to have it on both AP and CPE ? we had it only on AP side... The big problem was that it was only working for 20 min then it stops working... ping...
Go down to 12-18 volt on the RB532 and power direct from a car battery with an old battery charger without switching tech.
Then it will work. I was disturbing the VHF band in sweden. for a cabel tv company
Hi all :-) i have to put in som info her ... 3 Meter Grids!! that are 9 Ft ,that will be arund 60-65 Dbi Gain!. And sure running H-pol in 5-6 Ghz over water is OK. We are running 42 km over water with 26 dbi grid and the speed is 55 Mbits TCP real speed :-). //Rickard 12' dishes are only 45dB of ga...
Hi! Check your settings on Antenna gain !,you have put in this "antenna-gain=53" !!! that totaly wrong! put in 0 then stuff starts to working :-) Or to a reset of your client CPE and start all over with default settings. This is my setting on one Ap for 5 Ghz. check my settings on Antenna ...
Hi, We are running a 24 km PtP link with 26 dbi grid H-pol over a city and water. we get on R52 cards a signal -70/-72 db and we get today with R532 15-18 Mbits TCP. and we dont have clear fresnel zone.
I think i now the problem :-) try to get 2 pcs of new Radio cards. it sound that you have broken diversity chips on your cards. i have hade that problem like 100 times now :-( . and it depends on the verry ESD sensivity CMOS chips, that get blown. //Rickard PS Im using that antenna that u are using ...
Yes we have this problem to. and to resolve it is to get a own DNS server.
The MT dns cant handel CNAME corectly and other problems.
i hope they update that code soon .

Hi there, thanks for your reply. My vendor Miro also accepted the problem. I need to change all cards now. Can you suggest which card is best for 2.4 and 5.8 ? ( The question is relevent - as we are facing too much problems of senao cards.. and really do not know why the same chipset from different...
I all. we are having the same problem her in Sweden... but . we rebuilt the antennas with better grounding, that helps some times. and i reparing the radiocards by removing the Diversity switch in the cards. then the cards working perfect again :-) so pleas do not throw the cards in the trasch cans!...
i have the solution for you Switch to a new Radio card. You have a broken antenna switch in the R52 card.
I have now in 2 months have sent back 35 pcs of the r52 card with broken antenna switch on.

Hi we had a strange problem.. we have upgrade our Main GW to 2.9.20 and i worked ok for 24 H but today it stop responding on http sites like Google (werrry slow) and Mikrotik.com did not show up at all:-).but Mikrotik.lv worked... but when upgrading to 2.9.21 then everting start working again....:-)...
I think the 2.9.20 is the most stable relase this year . I have upgrade 30Ptp links and 30 Ap cells. and everything is running perfect
and tomorow i will uppgrade 150 CPE units to 2.9.20
HI All. We have made a custom Apps that are pretty cool :-) that uses both SNMP and Telnet. And we are showing the Signal with a grapich bar red,yellow,green for the signal strenght. and you can set the SSID for diffrent base stations... and soon we can let the Customers Scan and then connect. and t...
I havent tryed yet , Its not so fun to reroll all the uppgrades in my network. We had alot of angry customers running with VPN to thier work.
But i solved it with 2.9.17. so i stay ther for a while .
We had the same problem with windows VPN(PPTP) but the 2.9.17 works.
I have tryed all MT versions from 2.9.10 (that works to) the other ones have the same problem. All works with the MT PPTP client/server.
but not with Windows.
I Think you will get at least 3-4 km distance. But if you have -76 in noise something is wrong!. i get at the maximum -92 ! and then i have 3 diffrent GSM and 3 G tellcos 4-5 meters away :-) and a 2.4 Ghz WISP ... but they ar running on V-Pol and im running on H-pol sectors 13 dbi.... So check your ...
Try to change your manual Tx power setting to default or to 21.
and put Periodic calibration to Enabled.
And update to 2.9.13 then u use the new Wierless drivers.
- LM Sensor (Working temp volts on standart Intel MB)
- Dual CPU suport that will be nice (then i can make use of Dual core)
- API for the Winbox so we dont to have make C++ programs all the time. and use Telnet...
-More UPS support like APC, Thrust, Belkin,...
Yes it will be perfect solution. and when i get my own designed antenna that can handel Both 2.4 ghz 19 dbi and 5.4-5-5.8 ghz 24 dbi in the same antenna , its in development state right now. Then i only have to change the a or b setting on the R52 card.
The main diffrent that im found is that the R52 is sensitive compared to the CM9 . And its handeling the Noise verry good.
We are running on 5.4 Ghz with 26 Dbi Grid antenna and the distance is 10 Km with signal -54/-58. and real trafic is ~ 25 mbits.
I hope is not avaibly yet i have my chipment with 100 Pcs of the RB511 comming this week and its more expensive.
at the MUM they dind think it will be redy for large order until late mars or april or ?
I use the (R52) 802.11a+b+g 65 mW Wireless miniPCI Card and it work like a charm :-) i have it today on 150 customers CPE units.

I was there But i hope next time to se more hardware from other vendors. And a presentation of the Mikrotik team They missed that . But i was nice to be there.
I wonder how they did becourse its not supported by Atheros ??.
but it seems to work . im running 2.9.11 Wireless test in my production network and it still works fine.
And the Noise floor is -95 Dbm... and the cpu load is lower...
Hi Michael, I think you have problems with your cabels or antennas. Im running 10 Km link with 2 pcs of RB532 Level 4 licens. And with Atheros CM9 cards and the antennas are Grid antennas 26 Dbi. the signal is -58 and i can lock the MT on 56 Mbit. And the ping time is 1-2 ms. And if i try the same l...
I have update my all AP RB532 and that working fine.
and my other X86 verions working fine to
And finaly it dont disconect the users on AP anymore !! (beefore is was every 10 sek)
Nice it working verry good the 2.9 release :-)
i have uppdated in production 5 PtP links and 4 AP cells. working verry god. and the ping time is around 2-3 ms on a 10 Km PtP link with -73 dbm in signal and 24 Mbits.
Im sorry yes it will work on one MT box but i dont whant to have the main router and the proxy on the same box. We have 2 main routers with fail over and one proxy server.
This is my settings. we are running Hotspot on 192.168.254.1 on port 80 and the proxy is on IP 192.168.254.4 and port 8080. And this setting works for like Http downloads from Microsoft etc.. ******On the Main GW MT Router***** / ip firewall dst-nat add src-address=192.168.0.0/16 in-interface=Ether2...
Yes it works... we do that on our system but i dont think MT support 2 drives. i use one 120 Gb SATA disk , and that work.
from the Main router we use transparent proxy with parentproxy, to a second box with proxy enabled.
