== The Linkysys WRT54GS v2 won't turn on ==

'' The router won't boot up. ''

=== Power Supply ===

Verify that the power supply unit is fully plugged into the router and a working electrical outlet. Also, verify that the power supply unit is not defective. You can do this by testing the power supply on another router or similar device that uses the same power supply unit. If it is damaged, obtain a new power supply that outputs a minimum of 12V 0.5A.

=== Power Connector ===

If the power supply if working, then the power connector on the router is defective. If you are comfortable with soldering, follow [guide|7183|this guide] to replace the barrel power connector. If you do not want to perform any soldering, follow [guide|7127|this guide] instead to replace the entire motherboard.

== Wireless Signal Problems ==

'' Connected devices have a weak or no wireless signal. ''

=== Distance to Router ===

The specified maximum distance for Wireless-G routers is 100 meters or 328 feet. The wireless signal grows weaker as your devices moves further away from it. The signal will also be weaker if it has to travel through walls. Reduce the distance and number of walls between the router and the devices to improve the signal.

=== Damaged Antennas ===

If the antennas on the rear are damaged, you need to replace them. The model number for the antennas is HGA7T. Follow [guide|7124|these instructions] to replace them.

=== Damaged Antenna Ports ===

If the antenna ports on the router itself are defective, you need to either replace the antenna ports themselves or the entire motherboard unit. If you are comfortable with soldering, follow [guide|6795|this guide] to replace them. If you do not want to perform any soldering, follow [guide|7127|these instructions] to replace the entire motherboard.

== Internet Connectivity Problems ==

'' The devices are connected to the router, but there is no internet connectivity. ''

=== Bad Ethernet Cable ===

Verify that there is a functional CAT5 or better ethernet cable connected to the internet port on the rear. Obtain a new ethernet cable if it is damaged.

=== No Local Internet Connection ===

Verify that there is a valid internet connection in the building where the router is being used. Contact your internet service provider if there is a problem with the building's internet connection.
