Playing xbox (NOT 360, the old one)

This may mean that your console is suffering from a power problem here . If your console not receiving enough power it will turn off whatever is wireless to conserve the power to keep the console on. Make sure you are not plugged into any surge protectors or and any extension cords.
If the controller is only flashing twice and not connecting to your console If you are playing on your Xbox 360 you can turn the console off by holding the power button for about 10 seconds and once it is turned off you can unplug the Xbox 360 for about 30 seconds and then plug it back in and power it on.It could just be a bad controller then or the controller needs to have the battery pack in it be replaced.Or it is a broken controller.

Some XBox games have both a 360 and original XBox version, so you can't play them on the 360. Other games simply aren't compatible. Your game may fall into one of those two groups.

It sounds like there is a probem with the RF Board (google search it). Problems occur with this from time to time when a sytem is disassembled and reassembled.

Run the network tests from within the 360 menus - looking especially at the result for network address translation (NAT). If this is either limited or fail, you will need to change your router for one which is compatible with xbox live. Try xbox.com to work out which routers are recommended.

As far as your router kicking him when you connected your pc, then you must have altered the access permissions of the router maybe by accident.

If all else fails, turn off the pc, router, modem and 360. Find the reset button on your router and press/hold this for at least five seconds. Turn on the modem, then the router. Let that settle for a minute, then connect and setup 360 and laptop.

There is a little white buttom on your xbox , this is the sync buttom , on your remote there is a small round white buttom too ( sync buttom again ) press those 2 and it will find your new controller

My pelican wireless network adapter(PC) stopped working one day. Only 3 of the 4 lights light up and I can't connect to xbox live. I've reinstalled and reset and reinstalled. Nothing works!

Console-to-Console Connection: Wireless Some Xbox games offer console-to-console, or system-link, play, in which two or more players (depending on the game) can wirelessly network their consoles for multiplayer use. Console-to-console wireless networks are also known as ad-hoc networks. In ad-hoc networks, a wireless adapter on one device connects directly to a wireless adapter on another device. An Internet connection isn't shared with this type of network, and the console-to-console connection is typically temporary. For console-to-console play, you need: Two Xbox 360 consoles. Two Xbox 360 Wireless Networking Adapters. An Xbox 360 game that supports system link play. To wirelessly connect your console to another console: Attach an Xbox 360 Wireless Networking Adapter to the back of each console as described in Use Your Xbox 360 Wireless Networking Adapter. On each console, go to the System area to enter your network settings. (They will be the same for each console.) If all settings are correct, exit the System area. The consoles should now be wirelessly connected to each other.
