new imac has random network connection problems with router
Mac user for over 10 years.
The new Imac randomly drops the connection to the network, most times does not connect at all.
I have troubleshot everything by searching online forums. I think the Airport card is defective at this point. I have set channel to 11, tried every form of security, network diagnostics, restarting, clearing the key chain entries, updating Router firmware, etc....
The problem is so random...I could be connected to the router/net and then all the sudden the airport bars goes down 1 then 10 seconds later , it goes down 3 more, then finally to nothing. and the connection drops.?????
