Can anyone please help with: 1 - whether it is possible to get my i-mac with airport extreme card talking wireless to my BT Broadband 1800HG wireless hub? 2 - how I do this (in REAL simple terms) 3 - if I can do this what do I buy (and so assuming I need a new hub) then what do I buy. Apple say I need to change my hub from pppoe to pppoa (???) and BT are bloody useless. Many thanks to anyone who responds.
