unknown mac addr appears after modem reset
my modem did a spontaneous reset today and when it came back I had a new device:
mac addr = 02:99:99:xx:xx:xx
02:99:99 is not a known vendor code
the lower part was only one digit away from the lower part of the mac address of the router
the ip address was 192.168.0.252
i logged into the modem and saw 252 was a reserved client ip
i called cox. they claimed not to know anything about it
i'm writing to this forum to see if anyone has had a similar experience
thanks in advance
