D-Link DSL-2750B: Can't connect to new router
Hi, power the Xbox off by pressing and holding the power button for 10 seconds, then pull the power cord out of the Xbox, then pull the power cord out of your modem/router and leave both power cords out for at least five minutes. Reconnect the modem/router
to the power first and let it obtain an internet connection, then reconnect the power cord to the Xbox and power on using the power button on the Xbox and try your wireless connection again.

If all else fails factory reset your modem/router and start over.
