It *is* odd, huh? The MAC address showing in the field is not even close to
any on my network (including the router or the cable modem). It could be
just a firmware glitch but, because i'm a geek, it bothers me that I have to
keep MAC cloning set ot "Enabled" just to keep my network up. Perhaps I
should set it to "Disabled," power the modem and router down, wait, then
bring everything back up one at a time. I hope to have some time this
weekend to play with the network, so I'll try again and keep my fingers
crossed.
