Trouble Shooting

Some systems just will not support 802.1x. There is an existing work around that allows these devices, such as routers or Xboxes, to correctly DHCP.

  • Make sure the machine is registered. This will not work unless it is.
  • Set your machine to DHCP. Also will not work without.
  • Plug your non-802.1x device into a port (802.1x or not)
  • Wait 45 seconds to a minute. This allows the automatic detection of 802.1x authentication to fail, falling back on the older method of MAC registration
  • Have your system re-DHCP. This differs from machine to machine, but the following works for windows:
ipconfig /release
ipconfig /renew
