Wi-fi problem [solved]

[nw1456]

Hi,
Has anyone been having a problem with wifi? Or just me? Had this laptop since last year, installed Mageia5 and been running it ever since both wired and wifi. Was working perfectly this morning. Took it to a friends house this evening, couldn't connect, couldn't even see any networks, odd methinks! Gets home and will not see my network! Fired up Win 8.1 (yeah I know...shoot me) could just about remember the login password.. connected fine. Another laptop running Ubuntu Mate, connects fine. I'm even running UM on a try out disc on the main laptop and that works fine. Does seem to be a Mageia problem.

I'm at a loss, any ideas people?

Thanks

That's a pretty generic question, as wifi problems can be pretty diverse, and some more detailed information would be needed.

Which desktop environment are you using? Do you use net_applet or NetworkManager?
And please provide the output of the following commands:

Code: Select all

lspcidrake -v | grep -iE "wlan|wifi|wireless|net"
ps -ef | grep -v grep | grep -iE "net|wpa"


and, as root:

Code: Select all

ifconfig -a
rfkill list all
systemctl status network.service -a
journalctl -ab | grep -iE "fw|firmware|iwl|wifi|wire|80211"

Hi,
When setting the network interface, MCC ask "Allow interface to be controlled by Network Manager", answer Yes or No, but never Automatic, it seems this choice isn't safe. It isn't easy to find out why, but it is worth a try.

Hi, thanks.
Running KDE. I use the small globe/network icon on the taskbar, so I assume net-applet? Here is the output you asked for.

That's your problem, wireless is disabled. Is there a keyboard shortcut or function key on your laptop to enable wireless? Can you please try to toggle that once, then run the above command again to see if anything changes?
If it doesn't, try running the following command as root to unblock it:

Code: Select all

rfkill unblock all

You're a genius! I never even knew there was a key to toggle wifi (got a tiny little wifi symbol on it). To be fair I hardly ever use the laptop keyboard as I mainly use a seperate monitor and keyboard, must have pressed it inadvertently transporting it yesterday. What a fool! Thanks for your help.
