I rebooted the other day, which got me a new kernel (3.2.9 ((I think I was running 3.2.1 before, which got uninstalled. Fedora helpfully left 3.2.6 and 3.2.7, neither of which I think I ever booted into.))), and now it seems my wireless (rtl8192ce) has become really flaky and unstable. At first I thought it was the router playing up, but everything else in the house works fine (everything else in the house is made by Apple it seems).
Typically it fails to associate until you reboot the router (which is why I thought it might be the router) or occasionally the laptop. When it is connected performance is occasionally crappy. I’m totally out of my depth debugging this. I poked around a bit but found nothing meaningful.
