Wifi stopped working after yum update - CentOS 7


I had my wireless internet connection working OK after installing kmod-ath5k.

Anyway, few days ago I ran yum update and NetworkManager was installed/updated. I guess that this caused some kind of incompatibility with previous method and now I cannot access Internet.

I just tried to remove some stuff and mess on some config files, but I could not fix it.

Are you able to help me here ?

Thanks.

Hi

that website talks about finding correct drivers, installing them, configure, etc etc..

This is not the problem as the connection was working in the beginning.. just stopped after running yum update. So, this should be as simple as try to disable NetworkManager or force connection to use first method, just dont know how.

Hi...

Ugh...this is why I don't like doing software/OS updates on Linux. There's always a risk of stuff getting broken.

Not sure I can help but what distribution and version of Linux is this? Was Network Manager installed fresh or just upgraded? What was the "previous method" you referred to? Is your network (or any network) seen at all by the adapter?

Also, can you open a terminal and post the results of...

Code:
lspci -nnk | grep -i net -A2
Thanks!

kmod-ath5k

the kernel mods MUST !! match the kernel used

if there is a kernel update then the KMOD also MUST!!! be updated

normally this should happen on the SAME day as the kernel update -- but not always

you might have to wait a few days ( or months sometimes on rare occasions ) for a updated kmod to be released


rerun
Code:
su -
yum update
then see if your" kmod-ath5k " matches your kernel
Code:
su -
yum info kmod-ath5k
--------- and -----------
yum info kernel*
