MAC filtering denies internet access to machine2? please h..

Archived from groups: microsoft.public.broadbandnet.hardware (More info?)

I have a cable modem going into a linksys router. I added a WAP and
wanted to enable MAC filtering. (I've since removed WAP to
concentrate on one problem at a time). When I enable MAC filtering,
my other PC could not browse the internet, but I could still see it on
the network and access it, etc. When I removed the MAC filter,
everything was cool. So it is the MAC filter. I double and triple
checked the MAC address on my other PC and it is fine. Any ideas?
Thanks,

Rob
