Četl jsem mnoho dalších postupů na toto téma a vyzkoušel jsem řadu věcí, ale stále stejný problém.
Upgradoval jsem ze 14.04 na 16.04 – a tehdy začaly problémy. Moje bezdrátové připojení je perfektní – speedtest.net ukazuje rychlost stahování až 65 Mbps. O něco později (asi 10 – 20 minut – v závislosti na využití), když si uvědomím, že se mé internetové připojení zhoršilo – stejná kontrola rychlosti vrací rychlosti až 0,5 Mbps. Pokud budu pokračovat, v určitém okamžiku to úplně selže, když se wifi odpojí, a pak se neustále pokouší znovu připojit bez úspěchu.
Pokud spustím tyto příkazy
sudo modprobe -r rt2800pci
sudo modprobe -v rt2800pci
Spojení je opět perfektní. Dalších 10 nebo 20 minut a pak se to samé opakuje, dokud to znovu neresetuji.
Jakékoli myšlenky na to, co by to mohlo způsobovat, nebo jak mohu udělat „opravu“ trvalou, budou velmi oceněny.
Moje „wireless-info“ vrací následující

Přijatá odpověď:
Konečně po více než týdnu frustrace – myslím, že jsem našel řešení tohoto problému – z toho, že je tu někdo jiný, kdo si chce vytrhat vlasy, to nedělejte.
Zdá se, že řešení tohoto specifického problému – který jde ruku v ruce s otravným
rt2x00queue_flush_queue: Warning - Queue 2 failed to flush

Doufám, že to pomůže někomu dalšímu!!

O hodinu později jsem si všiml, že rychlost internetu opět klesla na 1 – 3 Mbps… a v /var/log/syslog jsem si všiml, že se to stalo ve stejnou dobu jako problém IRQ16.
Postupoval jsem tedy podle doporučení přidat „irqpoll“ do možností spouštění.
Chcete-li to přidat v Ubuntu 16.04 – je třeba
Upravit soubor /etc/default/grub Upravit / Přidat řádek tak, aby zahrnoval následující
GRUB_CMDLINE_LINUX_DEFAULT="irqpoll"
Pokud tam již hodnoty máte – přidejte je na konec jako
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash irqpoll"
Chcete-li aktualizovat grub cfg, spusťte následující
sudo update-grub
Zda byl irqpoll přidán do vašeho souboru cfg, můžete zkontrolovat provedením
cat /boot/grub/grub.cfg | grep irqpoll
Měli byste být schopni najít několik záznamů.
Po REBOOTU – můj stroj byl perfektní – 24 hodin zapnutý – stále platí!
