The most important is that RB4011 became inaccessible and only the power reset can bring it back.

I don't know why and I can't reproduce the issue on demand, maybe the loop, maybe not.

I've an issue with newly purchased RB4011iGS+. It occasionally become inaccessible. It happened twice, today and two or three months ago. When it happens, - Inaccessible via ssh, winbox, www. - Only responds to ICMP ping. - RSTP is not working. - Logging to file is stopped. - Other services seems wo...

When disabling a connected PPPoE client, the status stays at 'Terminating... administrator requests', but not 'disabled'. Disabling a not actived dial-on-demand PPPoE client, the status goes 'disabled'. I use a script to detect pppoe real status, (it has a delay between disabled and disconnected), i...

Thanks, it works after restart the router.

To clarify, it's not "bricked", if you can fix it so easily.

... half-bricked, what every.

ROS 6.5 bricked my RB951G-2HnD too, with updating from 5.26 . I've upgraded from 5.26 to 6.4, downgraded back to 5.26. But upgrading from 5.26 to 6.5 makes RB951G-2HnD bricked. Since 6.5 has some issues to me so I want to downgrade back to 5.26, but I'm afraid it bricked again when I upgrade it to ...

Ok, If ATU do something wrong, I do it the same wrong because i have the same problem and can't find a solution. Simply... simple queue does not work You can add/enable queue tree rules one by one, and watch the counters. Once the counters frozen, the rule just added has the most suspicious to caus...

You are doing something wrong. Bug reported by Bi11 is fixed long time ago.
my queue tree is working fine and i can't see anyone else complaining lately, so jump to conclusions yourself

My queue tree is working too since ROS 6.5

Is RB915G affected by MetaRouter random freezing issues too? Two days early I set up a metarouter on RB915G. At afternoon today, when I hit redo in winbox, the router is not responded, so I clicked redo a few more times. Soon I noticed the CPU reached 100% and the router is frozen, Winbox was discon...

I connected a PPPoE through ADSL modem, over a Ethernet port. ADSL modem is connected to the ISP telephone line. The PPPoE bandwith is limit to 4Mbps by ISP. Connection between the Ethernet port and the ADSL modem is 100Mbps, which is showed on the interface status page. Here is a weird graph, on pp...

My ISP may block PPPoE temporarily if I re-dialed too fast. I need a few second interval before the next retry. Currently so it re-dials immediately after disconnected, so I can't get connected because ISP blocks me, may it think this is a brute-force attack? When this happens, I have to disable the...

I want to drop some incoming UDP packet by matching binary content e.g. <UDP header><fix length binary data>\x00\x00<any binary data> How can I do that? I only found two ways to filter the packet 1. filter content rule. this only match simple fixed data (\x00 is not working) 2. L7 protocol cannot ma...

Ditto happened to me. After I upgraded routeros to 6.4 from 5.2, the queue tree shows all zeros and is not working at all. I guess the bug is happened when calculating the max-limit for each queue. parent max-limit=5m +- child max-limit not set is not working. may be it was treated the max-limit to ...
