I had to update the WAP11 firmware to get the AP client checkbox in the setup utility.

Gosh, you're right, according to the user guide. Someone should tell the author of that other page.

But, it will defintely only be a client to another WAP11.

I can's speak for the D-Link personally, but I am pretty sure it's the same thing with all inexpensive, AP client-capable access points.

That sucks. Has anyone here tried the Netgear ME-102? That, apparently, supports AP client if you update the firmware. (http://www.netgear.com/customer_support2.asp and look for "Firmware Upgrade")
