wifi times out after every five minutes only in ubuntu 20.04 works fine in windows.

[saaim]

I tried setting power management off
setting the wifi.powersave = 2
disabling ipv6 settings
changing router channel from auto to 9
I also tried reinstalling ubuntu and updating kernals this seems to be a common problem with QCA9377.

lspci -knn | grep Net -A3

I don't have this network adapter but I will give what pops to mind:

- I would not use channel 9. Recommend you use only channels 1, 6, or 11. Also recommend you use a Wifi Analyzer app on a smart phone to determine which of those channels is least congested.

- The wifi APs and routers I am familiar with have a Power Save setting. You could toggle that to see if it makes a difference.

- Recommend setting a fixed 20 MHz bandwidth for 2.4G.

- If your Power Level is set to 100% and you are close to the router, you could try turning the power level down.

- Recommend Security be set to WPA-2 Personal with AES.

- Recommend you try different Mode settings such as: 802.11n only, 802.11 g only, or mixed to see what happens.

- Look at and research the other wifi settings that your router has and test the settings.

- Recommend you use "Forget Connection" for all current interfaces so you can start fresh each time you changes settings in the router.

Good luck.

Lets see

iwconfig
ifconfig -a
iwlict chan
sudo iwlist scan
dmesg | egrep 'ath|firm|country'

Which country do you live?

hi Saaim, I am having exact same issue for already more than a year and a half... Ubuntu 20.04 with QCA9377. Have you found a solution? thanks!
