[SOLVED] Wireless Card Instability (generic problem)

Post by unavailableartist »

Hi it's me again, and I'm still having internet troubles. I recently replaced my network card to Intel Wireless 7265 it works in linux mint however it only works for a short time before it stops loading web-pages and crashes. Also, if I toggle off the wireless, it will disappear all together.

Code: Select all

inxi -n
Also states that the network card doesn't have a driver.

this is what I got for

Code: Select all

inxi -frxxxz 
returns

Code: Select all

Is power management on (it should be off)?

Code: Select all

 iwconfig

That looks to be it so far. I turned it off, it was on for some reason (maybe by default).

thanks! I'll update to solved depending on how it keeps going.

Yes this was 100 percent the problem, the wireless card works flawlessly with power management off.

However, every time I reboot, it defaults to "on", so I have to retype in the terminal. I don't mind, but is there a way to disable it automatically so it could be a bit more user friendly to other people who use this computer?

With power management on, do:

Code: Select all

 sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf 
Reboot
