Er, with wifi. Alf Watt, ex-Apple engineer, has been speaking specifically about wifi issues, he’s not left the company to become an agony aunt. Mind you, if you’ve ever hung out of a hotel window trying to get a signal, you’d take anything.
He spoke with The Mac Observer and really spoke: they’ve done a podcast interview that goes into a lot of detail. But the MO site also includes a breakout description of the most useful points, including screenshots for those of us who don’t spend a lot of time deep in Wifi dialog boxes.
