Thanks Tuttle, I have done as you suggested, the security LED on the router is lit, I am surfing, and all seems to be ok. Is there any way to test security other than a trusted friend with a wireless laptop? And, this is not too important, but it bugs me that I cannot now surf into my modem through the router. What might be the problem? Showing my ignorance here, but how is MAC filtering so easily bypassed? I am new to networking. I may yet flash my router with DD-WRT, but haven't yet done my homework on that, so that will be sometime in the future if I do.
