Same problem with .162 and .167

Using a Netgear DG834G with a 128bit WEP key. All works, and the Netgear spots the MAC address of the connected BB. Then I set MAC address filtering on on the Netgear and the BB can no longer communicate, even though its MAC address is listed with all the others on my network in the Netgear.

Anyone else seen any compatibility issues with the BB's WiFi implementation and some routers?

Are you using the latest firmware for your router?

Yes.

This could of course be a bug in the router or the BB...

I've used mac filtering on my router with my Curve and it's always worked just fine.
