He was screwing around and hit the reset button. Both Computer 1 (this one - where the router is based), our X-box Live, and Computer 2 (in another room) couldn't connect to the internet. We somehow got Computer 1's internet working again (obviously), but the X-box live and Computer 2 still can't connect to the internet. The router evidently needs to be re-configured or something - a friend of mine of mine came over and had a look at it and said that the problem was the router and the modem aren't communicating with one another. We've called Dell tech support or whatever and they are all a bunch of FOREIGN people with knowledge less than or equal to my own. The router is a Dell 2350. Anyone out there with expertise in this area that can help? Would be greatly appreciated. Thanks!if i were to take a quick guess...sounds like you were POSSIBLE set up with ENCRYPTION with key inplace, then it reset to default w/o encryption, but your devices are still set for encryption.

first try these steps in order.

1. unplug power to all modem, ROUTERS, computers, and xbox
2. go take a walk, 5 mins is good
3. plug in cable modem...wait 3 minutes...see if you get "internet or WAN led light"
4. plug in router...wait 3 minutes
5. plug in/turn on computers/xbox
