Upgraded an RB2011L from rc13 to 14. DHCP Client and DHCP Server would not issue to or bind to addresses. Downgraded to 5.24, all is back to normal.

I have tx drops on vlans on 5.21 as well. Tried disabling RPS and fooling around with the queues.

I installed 5.7 on two routers which are connected with a wireless bridge. The core router is an RB1100 which has about a dozen vlans. After rebooting the RB1100 the device was unresponsive. I drove down to the NOC and found that the ethernet port connecting the wireless bridge to my house did not h...

Who did you buy your RB450 from?

I just finished replacing the caps on 5 RB450's. Still no offers of compensation from Mikrotik or the reseller.

The three brown capacitors in the picture I uploaded are the replacement caps I purchased locally. Tom at Roc Noc may be able to take a picture as he has several blown RB450s on his hands.

I purchased 20 RB450s in 2008 from Tom at Roc-Noc. During 2009, each of the 20 failed. Tom mentioned that Mikrotik was aware of the capacitor issue and would offer a replacement of the 20 RB450s. In that time I've received a partial replacement. Sadly, due to the substantial delay in receiving the r...

I'll have to try to find a board that I haven't repaired yet. However I can point out the capacitors I had to replace in order to make the board operational again.

Thanks

Welcome to the world of Mikrotik.

I've had 20 RB450s with blown capacitors. The reseller has been successful in replacing some, the others I've just gone out and bought the 6.3v capacitor (I upgraded to 680uf) and soldered them in myself. You'll need 3 per board.

I got the same thing on 4.5. I ended up disabling management protection.

I get this same thing on my 3.20 x86 router and it locks up every so often...any responses? ip traffic flow is disabled...

The SIP helper is still not worth a squirrel fart in 3.14.

The wiki script doesn't work either in 3.4, thanks though.

Dear Tikers, I had a email backup script working in 3.3 that doesn't in 3.4. The script is as follows: /system backup save name=([/system identity get name] . "-" . [:pick [/system clock get date] 7 11] . [:pick [/system clock get date] 0 3] . [:pick [/system clock get date] 4 6]); /tool e...
