WL Router against ORiNOCO AP500

Hi,

I want to purchase a wireless router (with WEP encryption) to connect a
small home LAN to a ORiNOCO AP500 Access point at my office.

Frome the home LAN side the wireless link should act/be like a wired LAN
connection. Which router should I buy? Once ORiNOCO had the Residential
Gateway units, but I understand that those are discontinued. I need
something with the same radio power and receiver sensibility as the ORiNOCO
equipment.

Thanks for tips on this issue.

best regards

Tor
