pc interwebby problems. I need help!

[FORMULA51]

After i got the xbox live going i never plugged back in my pc to see if it still worked until last night. What i did this morning was unplug my ethernet cable from the xbox and plugged it back in to my pc. I then restarted my pc and the modem, turned them back on, and now my internet can't find a connection.

I did that "ipconfig/all" at the cmd prompt, and now it won't show the subnet gateway, it won't show the ip address, the dns settings, nothing. Before i got the xbox working, i could pull all these up in the cmd prompt.

What can i do to fix this? I'm going to buy a router this weekend, but need to get on the net before then. Thanks for all your help!

You with Comcast? Call tech support and ask them to troubleshoot your modem.

ya i sure am. So you think they can just reconfigure my modem again. like their cable boxes? If they do that will i lose all my xbox settings or no?

This seems like a DHCP problem to begin with. You might consider getting a wired+WiFi router. That way the router will own the single IP address from Comcast and will assign different, router-generated IP addresses to any machine that connects to the router (via wire or via WiFi) - and manage the traffic in/out. So the router acts as the DHCP server, assigning client IP addys automatically, and the individual machines ("clients") connecting to it don't need any special settings - the router takes care of all that.

I may not have a correct understanding of your setup, but having a router seems like it would help your situation.

Here is you comcast tech support. Check to see if your LAN(local area connection) is enabled. Start-control panel-network and internet connections-network connections, it will show all your connections. What modem do you have? What does it look like?

its a motorola sbv5220 fairly small and black with a whole lotta blinky lights :D

Are all the lights on or blinking? If so your modem is fine.

Not necessarily, I had a modem go bad, when it did all the lights where on but it didn't work. Comcast tech came out and replaced it.

With that modem if all the lights are on and blinking then it is fine. The motorolas are a great modem and have very little problems.

Mine was an older Motorola, tech guy said the version I had was known to have problems. It went bad within 6 months of buying it. The one that replaced it, same model but different version, has been working great for about 5 years.

Comcast modems do something that is a little evil. They pretty much "latch on" to one MAC address and that is all they will work with.

Did you have to call Comcast support to get your XBOX to work? Chances are, they reset the modem and it grabbed the XBOX MAC address and now it isn't going to work with your PC anymore. If you hook your XBOX back up, I bet it works perfectly.

The real solution is to do what your other thread suggests and get a router. Get the Comcast modem working with your router, and then let the router do all the rest.

I'd just try resetting the modem.
As others have said, stick a router between the comcast modem and your internal lan.

I see those quite frequently - easiest solution is to get a pen and press the reboot button on the back of the modem - the modem is trying to look for the MAC Address of the Xbox so it is not letting go. If you do a reboot, it will look for the next available mac address (your PC)
