I've been unable to get WiFi reliably working firstly on Ubuntu and now on Arch. It potentially seems like a hardware issue, but it was flawless on Windows - then I switched to Ubuntu and it would occasionally connect after many times of trying, but it wouldn't last for long. I thought it was just a problem with Ubuntu so I switched to Arch but it's remained. And when it does work then it's painfully slow.

When I run wifi-menu I get the following:

Scanning for networks... Could not set interface wlp3s0 flags (UP): Input/output error
n180211: Could not set interface 'wlp3s0' UP
Could not set interface wlp3s0 flags (UP): Input/output error
WEXT: Could not set interface 'wlp3s0' UP
wlp3s0: Failed to initialize driver interface
failed

But again, this is only when it stops working. Generally what happens is I turn on my computer, and the WiFi "works" although I need to keep reconnecting and it's very slow. Then after a while it cuts out seemingly permanently, and this is when the above errors occur.

I don't think it could be a hardware issue because it would be a massive coincidence for it to happen on the same day that I switch from Windows to Ubuntu. But the IO errors make me question this.

All other devices are fine so it's definitely my computer, unfortunately I don't have any other network to test with.

  • If you suspect a hardware issue, it would be very useful to tell us which hardware; specifically A) the make of the computer B) the model obtained from the serial number plate (specific reason for that) C) the make and model of the WiFi adapter.

  • Welcome, could you add the output of lspci -knn | grep Net -A3 – GAD3R Apr 24 '19 at 20:25
