Recommended AP for test purposes.

Further to a previous I believe I'm using an AP that does not act as a NAS. In particular there are no aspects of the security page that ask for Radius configuration. I'm using a Belkin Wireless G Universal Range Extender/Access Point (FCC: K7SF5D7132A). Can anyone confirm my suspicions? If so, can anyone recommend a reliable AP suitable for doing some testing on. Thanks in anticipation of replies, Garvin.
