I have had a netgear wireless DG834G v2 router set up for two years with no problems. I logged onto this network via my desk top and laptop using 128 encryption and a 13 character passphrase (windows xp). My laptop died recently so I’ve just replaced it with a sony vaio which has windows vista on it. Now it sees my network but despite putting in the same passphrase it tells me that can’t connect. Any ideas please?
