My iMac G4 (in sig) has been fine on 10.4.11 on a wpa2 network with an airport extreme card. I stared to get "there was an error connecting to snow" so I changed the channel my router was on all worked fine turned the iMac off came back the next day same error again. Then I re-seated the airport extreme card in the iMac again it connected and everything worked. This time I turned it of then back on and I was back to the error again. I read about deleting the key chain but I couldn't be bothered in all that so I wiped the HD and re installed tiger to make sure there was nothing wrong software wise but still its the same error. Im now running out of ideas and I'm starting to think its the card but if I turn all the security of the router (its a Netgear draft N one) then it will get the hump and then finally connect. Any ideas anyone, thanks in advance Update: After some poking I have managed to get it to work but now when the iMac is turned on it requires the airport to be turned off then on again for it to connect to my network is there any way to fix this??
