When I wake my MBP from sleep, it takes ages to connect to my home network (a wireless G router, with latest firmware) - at least 15 seconds and sometimes more like 25 seconds. I thought this was odd since it used to take less than 5 seconds on my Powerbook G4 under Tiger. I have narrowed the problem down to network encryption - with either WPA or WEP encryption enabled on my router, it takes significantly longer for my MBP to connect to the network. However, with no encryption it is < 5 seconds. Anyone have any ideas on whether this is Leopard or my router at fault?
