Re: ath9k problems on openSUSE 12.3

[Gerry Gavigan <gerry@gavigan.f9.co.uk>]

Thank you for replying

Unfortunately while I understood every word I don't understand what to do

For example by "once-only" do you mean that once written that's it forever or 
do you mean once during install

For example I'm fairly sure everything was reasonably fine with 3.7.10 but when 
I ugraded to 3.8.7 for better gma500 graphics chip compatibility things went 
wrong for wifi but a revert has achieved nothing

Should I remove the battery from the netbook then do an fresh install of 
openSUSE 12.3 with 3.7.10? 

or something else?

Sorry to take up your time 

Gerry
