why only Ethernet port 10/100? which routerOS supports PWR-Line ? is there any manual ?

ringlet

I have problem with two rb750GL both of them after upgrade to 6.40.5 are working fine for some time and then just freeze. I see them from other MT in the same bridge but cant log in , then go reboot and work fine for another 12 to 24 hours. Routerboard bios flashed to 3.41 , now I added WD to neares...

ringlet

http://prntscr.com/3lrqfx

ports just go down only reboot helps but only for couple of hours ...

ringlet

i think that there should be a little bit of log ...
i would like to know if port is going down or up or flapping in let say 10 minutes ...
or that somebody was logging to switch during a day ...
simple but very useful

ringlet

please correct me if i am wrong: 1. i don't see any SNTP implementation in this device? 2. i don't see any logging at all ? 3. there is no information about igmp snooping so there is no igmp snooping? 4. there is no possibility to name ports ... 1. No SNTP or time only uptime 2. No log or syslog 3....

http://prntscr.com/177ezn i have 22 channels in my scan list, previously it was in one line , now it is in some kind of matrix and a cant use nothing what is below matrix. This is normal.

what was your previous firmware version?

ringlet

there is also new firmware version:

current-firmware: 3.0
upgrade-firmware: 3.02

ringlet

is there only nv2 stability improove or maybe some more like tcp better throughput ?

ringlet

does anyone try to increase MTU value on every device in the row? I'm not sure but i have suspicion that there can be a problem http://wiki.mikrotik.com/wiki/Maximum_Transmission_Unit_on_RouterBoards#MPLS.2FLayer-2.5.2FL2.5_MTU http://forum.ubnt.com/showthread.php?t=51867 https://forum.ubnt.com/show...

nstreme is the only answer

try to change 2x2 on 1x1 HT it should prevent from disconnects every 5-15 minuts

ringlet

how to resolve this problem: if U have p2p bidge in 2x2 and then MT with AP - U should change 2x2 on 1x1 and change nv2 to nstreme on the bridge So, back to 3 years ago. :? or... put some fiber in to ground like we did ! there is more , You can always buy professional radioline ... no good news ...

ringlet

how to resolve this problem: if U have p2p bidge in 2x2 and then MT with AP - U should change 2x2 on 1x1 and change nv2 to nstreme on the bridge then U can leave nv2 on AP nv2 should be used only at the ends in AP , no nv2 with p2p bridge ... we tried everything nv2 is dooing "something" w...

ringlet

so Mikrotik team, will You try to help us? Will You investigate this issue ? I see more and more posts like that in local forum in Poland ( trzepak.pl ) also on ubnt forum and here on Mikrotik forum , so I gues it is not only my problem...

ringlet

I'm really happy that not only I have this problem, and that in the end the team Mikrotik deal with this problem. Maybe something will finally be explained.

ringlet

but thats the problem ! that nv2 cuts tcp to approximately 9-12 Mbit
same problem here ... after changing to nstreme tcp increases to 30-40 Mbit on machine

no 20 sessions - 1 session more bandwidth we need ! speedtest is only 1 session .....

Hi, i am still looking for answer for this situation: A <------> B <-------> C A - rb750 B - rb711HnD (AP) C - sextant (CPE) between A and B is ubiquiti transparent bridge btest A to B 1 tcp session 42 Mbit , 4 sessions 50Mbit btest B to C 1 session 30-35 Mbit , 4 sessions 40-45 Mbit and the riddle ...

ringlet

hi, i think i have similar problem ... first there is rb750up then there is wireless bridge on ubnt equipment then there is rb711UA-5HnD and again CPE on rb sextant -tcp performance ( always 1 TCP session ) from rb750 to rb711 around 40-45 Mbit -tcp performance from rb750 to sextant only 20-24 Mbit ...

ringlet

Hi, can anyone explain to me why when udp btest working on 100 Mbit in the same moment TCP btest on 2 sesions gives only 20 Mbit speed, when i take 20 sesions then i get 45 Mbit (test made on rb750G behind that p2p bridge ) but on some links the same tests give other results like 100Mbit udp and 50 ...

ringlet

is this on wireless or wireline.??

wireless bridge connected to d-link switch on both sides

ringlet

you can disable "ip firewall connection tracking" and "bridge filter use firewall no" to improve TCP performance. i have done it before but dont see any better tcp connection it is funny becouse tcp test only via 1 p2p bridge from A to B or from B to C i going fine, but from A t...

HI, recently i have problem with getting good speed in my network where i have p2p bridge behind another p2p bridge. when a am doing BTEST from point A do B with 1 tcp connection i get about 45 Mbit then taking test from A to C which is last mikrotik in the row and a get only 10-15 Mbit with 1 TCP b...

When can I expect in a sextant with gigabit port version? Now I buy a normal sextant and assembled them with RB711G-5HnD.

ringlet

*) wireless - improved nv2 link stability to reduce control frame timeouts,
only AP requires update;

good work , it works! much better performance, till now 9 hours uptime , previously it was maximum 1h :]

Hi, I would like "to thank" the whole team mikrotik for having destroyed a really nice platform rb711, in looking for savings. I protest against such an approach. At least 30% of purchased equipment "rb711 MMCX" in the last four months have: - Problems with memory and gives the e...

first upgrade to RouterOS v5.0rc11 and report back. What is the distance for this link? I upgraded - still disconnects. I think that it disconnects now more often, every 3 minutes or so even when the traffic is low. The log messages are a little bit different - sometimes it's "disconnected, co...
