Airlink 101, can't setup wirelessly

[vpelton]

AirLink camera Model # AIC-250W/ANA
Linksys Dual Band Router, WRT400N
running on WinXP

Newbie here, so not sure if I'm using the correct terminology, but here goes.

I’m able to use the camera when it’s plugged into my router via Ethernet. I then tried to follow the steps to go wireless. Used the Setup Wizard, Web Config, System Admin, Management, Wireless. It says to click on Refresh until Link says Yes. But I’ve done that 50 times & Link still says Disable. How can I get Link to say Yes?

I'm using WEP security on my router. I entered the key as requested & it seemed to take it ok.

Thanks.
