Hi everyone... i have a 1st Generation iMac G5... i recently decided to go wireless... my parents have a PC downstairs and my imac is upstairs... I bought a netgear DG834G wireless ADSL router and an airport extreme card for my imac, both of which i installed successfully i opted to use WPA-PSK security settings and selected an appropriate password... the internet still works fine downstairs... when i click the Airport icon on my imac it does identify the network which i have named... i click 'join this network' and it prompts me for a password... i enter the password but it wont let me connect? it either says wrong password or there has been a problem connecting??? any help much appreciated, thanks!!
