I swapped out the intel wireless card for a Dell DW 1702,
and modified the AirPortAtheros40 kext.
I can connect to WIFI, and it works, the signal seems to be weak.
but after a long time, maybe not long but with a lot of network traffic,
the connection drops.
Is there something wrong with my card because I purchased a used one ?
Or is this a common situation for Dell DW 1702 ?
