 disconnections from the wifi which is set to g-only. Other wifi router

Hi Joe,
Thanks so much for getting back to me. Testing a new kernel might be a
little problematic since this is sort of a production machine. However, I
had already installed the OS numerous times this past week anyway and it
wouldn't be a disaster if I had to do so again.
I will try to see if there's a way I can back up the OS to an image so I
can re-install it if things blow up. Maybe you have another suggestion? As
another approach, is there a way to go back to the old i.e. production
kernel if the new one merely suffers from non-killer but significant
defects?
Thanks again,
Phil
