[H] Comcast blues

[Stan Zaske]

Have any of you ever run into a situation where your router's WAN port 
seems to stop working but your ethernet connections among 4 PC's are 
fine? Then after some more investigation it seems that your cable modem 
will only connect one PC to the web and none of the others? The only 
thing I can figure is that my router is fine but Comcast has locked 
(possibly) my service to the MAC address of this one box and will only 
connect to it but none of the others. Is my thinking straight on this or 
can any of you come up with an alternate scenario? It seems might 
strange to me that I can take the ethernet cable from my Mororola cable 
modem and switch it from one box to another and only the one will 
connect. What the heck is going on?
