since December 23rd my Wi-Fi on the Xbox is not working but on my ipod and laptop Wi-Fi is working fine. I tried turning off and on my monitor and Xbox but it still didn't work. I bought the wireless adapter and still won't work.
That being said, suggest that a sequential power cycle is the first step in clearing connection problems, and
the order and timing of the steps is important to success:
1) turn off the Xbox and unplug the power supply cord from the back of the Xbox then 2) unplug power from the router (Some folks have a combination modem-router AKA 'gateway' or only use a modem with no router. If either, skip steps 3 & 6). 3) unplug power from the modem. 4) Wait at least 5 minutes then replug the modem/gateway power. 5) Wait 'til the light on the front of the modem/gateway which says BROADBAND, ONLINE, READY, CABLE or DSL is on solid (not flashing), then plug in the router. If you have a gateway instead of a modem and router or a modem with no router, then when that
light says it's ready, skip to step 7. 6) Wait until the WiFi light on the router is on; you may not use WiFi, but it's still a good indicator your router is finished booting up.
7) Plug in and turn on the Xbox. For more background on Ports, see
