REDbar when playing matchmaking

Hello, i am redbar when playing matchmaking halo 3. What to do? I use my ethernet cable to the PC that has full green bar and is only a couple of meters away from the router.

  • My Xbox Slims inbuilt adapter is destroyed.
  • My Wireless Adapter is destroyed.
  • Cant use a PC-Adapter.
  • I dont have an ethernet cable long enough to the router.
  • My download speed is 11Mbit per second.

You could get a wireless ethernet bridge. Alternatively you could use a router with WDS or client bridge mode with third party firmware like DD-WRT.
