Hi and thanks in advance to anyone who can help. Here is the situation: I moved in with family who have a PC and router (Netgear) through charter (cable provider). However I've had an imac g3 450MHz for the past 8 years and it still works fine..except.. The OS is 10.4, and I seem to have a problem connecting to internet with wireless. Apparently somehow the original airport software was deleted. I did purchase an airport card and adapter and successfully installed that. However my problem is getting airport software back on my Imac. I tried installing Airport 3.1 however my computer insists its already installed so it won't install the airport software. But a search confirms that there is no airport any longer on my Imac. In any case, I'm not able to get on the internet. Please help.
