So after spending far longer than I'd like on tech support calls, I finally got the internet working at my new apartment. Problem is, I can only connect one device at a time. If I've got the Xbox on, my laptop can't get internet access, and if the laptop is on the xbox can't get assigned an IP address from the router/modem. The Comcast techs seem to be clueless as to what I'm dealing with. I'm using nearly the same setup as I was using at my parents' house but now it's not working. For some reason. How can I get internet on my laptop and two xboxes at the same time?
SB5101 Motorola SurfBoard modem
linksys 5-port ethernet hub
NO wireless capabilities, everything is through ethernet cables.
Do they pay Comcast for additional IP addresses ? Because that would be the only way it could work... Perhaps the hub was connected to a router or a combo modem / router gateway device and being used as an ethernet port expander ?
No, nothing special. Any ordinary home networking router will do what you need it to do. It's beyond the scope of these forums to give a tutorial on home networking, sorry. Perhaps you could Google for that info.
