I have a Netgear WGR614 wireless router connected to my WOW DSL modem and utilize WPA as security. wireless signal is good on first floor but drops significantly in my basement. I have a Netgear WG102 AP I would like to configure as a repeater and place in my basement to boost the WGR614 signal strength. What configurations must I apply to both or either devices to achieve this setup?
In all likelihood, you won't be able to repeat the primary router's wireless signal. The WG102 uses WDS (Wireless Distribution System) for repeating purposes. But as far as I can tell, the WGR614 doesn't support WDS. You could only repeat another WG102 repeater. Assuming this all the equipment you have, that leaves running an ethernet cable between them as your only other option.
Other options ($$):
1. Get a second WG102 repeater to form a WDS bridge.
2. Get a universal repeater to replace the WG102.
3. Get a pair of powerline adapters to replace the ethernet cable.
