The -5dB/1dB is a splitter which means you probably have cable tv too. Depending on the service you may only have one allowable MAC address. I am allowed 4 MACs, but, my modem gets "confused" whenever it has seen more than one MAC address without being reset ( It's a Motorola too). I have up to three machines going through one Linux firewall/router/PC and don't see any degradation of service. -- jludwig <wralphie@xxxxxxxxxxx>
