RB433 AH Ethernet Lock up problem.

pcarrillom · May 1, 2009, 5:38am

I have a pair of RB433 AH that randomly lock up ether1 port. These are being used like PTP bridge so I can log in via wireless and reboot and the port comes on line again.
Both have RouterOS 3.23 and last firmware.
I wrote to support, with supout.rif, no answer yet.

When the lock up, I can see the 433’s from other’s router in the same network segment via ip neighborg but canot ping or macping or telnet or nothing via the ethernet side.

The only solution is to reboot, accessing the router via wireless.

I think this is a very important issue, so if somebody has the solution (including mikrotik support) please talk now!.

Thanks

I have similar problem with a new RB433 300MHz. I updated to routeros 3.23 and firmware 2.19, but the problem persist.

I’m using the board with two mikrotik R52 wireless minipci, and 2 ethernet links in ether2 y ether3 ports.

Issue appeared in two more RB433 AH in different locations.

Still no answer from support. Has somebody received answer from support?

Mikrotik, we really need an answer here.

Thanks

post your question only in one place, making many posts in different sections of the forum will only upset other readers.

ok i hear u but my problem is troubling me alot

momi · May 7, 2009, 11:44am

Anybody get the answer yet? my second router 433ah has the same problem…

normis · May 7, 2009, 1:12pm

contact supplier for help, it doesn’t seem to be a software related problem, so forum can’t help you

pcarrillom · May 7, 2009, 11:25pm

Normis:

I really don’t think it is hardware related. In my case the problem is showing in all RB433 AH in my network, different places, different suppliers, different working time. It is totally random and forcing ethernet to 100Mbps FDX no ANEG seems to help.

Maybe you could take a deeper look on it.

daitea · May 8, 2009, 7:41am

it means you got it to work at 100mpbs on the ethernet port ?

pcarrillom: Can you remove RB from tower and test on your table sending data between RB and PC. And make /system reset-configuration before. When ethernet lock up what is both LED status ( one LED is on , other goes off and on or both LEDs blinking or no LED lights at all ) Then check ethernet status over serial cable in /interface ethernet ( connected or not connected, speed is 10Mbit or 100Mbit ) Then try pinging PC from RB I believe that information can help find problem.

i have the RB right here with me and its connected to this pc. The orange light stays on but the green light is off. i can only log into the board by wireless and if i reset RB i cannot enter anymore since i cant use the console null modem cable as well.

what do u think i can do
