Wireless randomly stops working...

English Network/Internet
#1

Hey guys, so here’s the problem. Sometimes, when i turn on my laptop, the wireless card is not available for usage. It simply doesn’t detect it. Now, the mechanical turn on/off buttons never worked for me under linux, so they don’t work for me turning them on or off. And the only pattern i could notice, was that when i leave the laptop turned off for the night, with the cable unplugged (but the battery is still present). Then, to make wifi work again, i have to shut down the computer, take the battery out, put it back in, and it seems this action sort of ‘resets’ the wifi card back to on.
Any idea how i could fix this issue?

Much obliged.

It sounds like a hardware issue.

If you have not already done so, then install “rfkill” and see if that tells you anything useful.

I found something that solves a similar sounding issue, but it’s for debian-based systems. Anyone could tell me what’s the openSUSE equivalent to this?

echo "options ath5k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath5k.conf
sudo modprobe -rfv ath5k
sudo modprobe -v ath5k

Thanks!

The Debian and openSUSE kernels are the same. Use exactly the same commands.

The first line is a complicated way of creating the file “/etc/modprobe.d/ath5k.conf” containing the single line:


options ath5k nohwcrypt=1

That tells the system to use that option when loading the “ath5k” module.

The other two lines remove (unload) the module if already loaded, and then reload the module so that it gets that option.

It’s certainly worth a try. On future reboots, it should automatically use that option.
