Guys,
I have the similar problem too. I just got a new set of wireless BT mouse and keyboard, and everything was fine until I go online. After a few experiments by turning the BT on and off, and clicking on the same link on Safari, I am pretty sure the BT is the problematic area. I even have the another computer right next to my IMAC G5 to make sure the network signal is good and strong. The result is the same: once i turn on the BT, the internet goes nowhere.
I am not sure it is a hardware related problem or it is a frequency problem. I double check many times, and there is no connection problem. Seem like the RF is interferencing each other ( i have wireless G network, Netgear WGT 624 router). I play with few different settings of the BT; but the result is the same.
Any one of you expert out there know what's going on, please let me know. Thanks a ton in advance!
