If the LEDs indicate that the network is working properly (Transmit/Receive LED blinks), check the TCP/IP settings of the network. 1. 2 LEDs Work But Client PC Cannot Connect to Network If the LEDs indicate that the network is working properly (Wireless LED is on, Transmit/Receive LED blinks), check the TCP/IP settings of the network. From the list of installed components, verify the TCP/IP -> Buffalo Wireless LAN adapter protocol (or appropriate wireless LAN adapter) is installed. [. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: · Re-orient or relocate the receiving antenna. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. · Consult the dealer or an experienced radio/TV technician for help.
