Comcast Modem problems, pleas HELP!!!!

Question

Ever since i've had my xbox i've used a 25 foot ethernet cable to connect my xbox to my modem and it's worked fine. But then i went on vacation for 3 weeks and came back and tried to play. Thats when the problem started. When i try to connect to xbox live it doesnt work and i go to test the connection. it tells me that the network adapter is disconnected no matter what i do. i went and bought another ethernet cable in hopes that my old one was damaged somehow, i came back home tried it, and it still won't work. Then i went to Best Buy and traded my Xbox in for a new one and it STILL WONT WORK!

Answer 1

If you left your modem plugged in while you were away then there's a good possibility a power surge took your modem out. I have Comcast and their modems are notoriously garbage.

Unfortunately you already went through all the trouble of trading your other stuff in and it was probably the modem the whole time. If you are like me you are leasing your modem so Comcast will replace it for free. Go up to your local Comcast place and tell them your modem is fried from lightning and they should replace it for free.

Answer 2

If it's connected straight to the modem it's probably the modem, if it's through a router then it's possibly the router that needs to be replaced.
