I recently upgraded the firmware on my D-Link access point, DWL-7100AP, from version 1.0 to version 2.00au, this fixed an issue with the number of MAC's that could be recorded against the AP from 16 to unlimited, however, it now seems to have caused a problem in that any machine using the Atheros AR5001X+ WIFI 802.11a/b/g card cannot get connectivity with the network. The network is seen but just cannot be connected to. I have tried updating the Atheros driver 1st with the microsoft approved driver, this did not work , then I downloaded the Atheros driver 22.214.171.124, yet again this did not work.
I have 16 WIFI notebooks 14 of which use this card, the other 2 use the Intel Pro/Wireless 2915 cards. Has anyone else experienced this and if so how have they overcome it.
I have spoken to D-Link but they were not aware of the problem and therefore do not have a fix.
