I have a weird problem with one desktop pc and the wifi connection. I have a Netgear WNDR3800 router, and a TP Link access point working as a repeater. To use the AP as a repeater I have to disable the security from the router (because the router does not support WEP security). But, I have activated the MAC filtering option to only allow known devices.
The weird thing is since I disabled the security on my router, this desktop pc can't connect correctly to the wifi (limited access and no ip assigned). But if I put the security back again, this computer connects correctly.
I have multiple laptops, and cellphones working fine with this router and the AP.
The desktop pc is running W7 and the wifi adapter is an Encore ENLWI-G2 (Realtek 8185 chipset with latest drivers downloaded from Encore's official site).
Do you know what might be the problem?
Thanks in advance.
