. While holding down the Reset button at the back of the
wireless router, plug the wireless router into a power source.
Release the Reset button when the Power LED at the front
panel begins to flash slowly, which indicates that the wireless
router is in rescue mode.
3. Use the following to set up your TCP/IP settings:
IP address: 1.18.1.x
