Having been working fine this afternoon, my wifi no longer works. I have run all the checks suggested in other posts and find that:
YaST reports the Qualcomm chip fully in Hardware Information
hwinfo does not
the firmware is installed and modprobe reports no problems
YaST Network Settings does not report a wlan connection
NetworkManager is running
wicked is not
Possibilities? firmware problem? a chip failure notwithstanding that YaST Hardware Information lists it? Any suggestions, please?
