I have noticed that the cable company does have to send a signal to a new box, they also once had to do something that sounded like 'clearing the cache' that is not done when you power it off and on. I was looking at this, Time Warner says it is compatible: Cisco-Linksys BEFW11S4 Wireless-B Cable/DSL Router
It may duplicate the services I have with the Wireless G except I'm not sure it has the N Network. It is the same form factor and will not add to the monster mash of equipment, will just stack. I was wondering maybe I could pick up one of these cheap and ethernet it to my wireless G to get the N network, which is what the extender I just got is using. My Wireless G says it is a broadband broadband router, but there is no place to attach a CATV, just an ethernet jack. I don't know how fast it is, tho...
