I installed Ubuntu Server 16.04.2 LTS on my laptop, an Asus TP500LA. I have it connected to wifi with the installed MediaTek MT7630E wifi card. It runs fine for about a day, then it becomes unresponsive.
kern.log
becomes filled with the same error:May 8 00:26:47 Claire kernel: [88167.420227] ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 0 failed to flush May 8 00:26:47 Claire kernel: [88167.456229] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 0 May 8 00:26:48 Claire kernel: [88168.640196] ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 0 failed to flush
This error repeats every couple of seconds, until I reboot it. It becomes so overloaded with this that the monitor starts being flooded with the error as well. Then I can’t
ssh
in, I just have to reboot manually.I have scoured the internet, and found people with the same problem, but it seems all the threads get cut short, or the solutions are way too tech-heavy for me, creating custom drivers and doing things that I don’t know how to do, with no explanation.
