Failure in transmision

So are you saying you have two different wireless Access points for a small network? Could they be interfering with each other? I looked up the products and they seem a little more complex than a small network might need.

Maybe try only one at a time, and since you can connect via wire, you should be able to access the router/abp via the web page, and see what channel it is on and the ssid, and verify that the wireless features are on. After that, try rebooting the apb, waiting a few minutes, and do a search for wireless networks.

I would not expect a random failure on both transmission and reception, so breaking it down to each component may help. Can any wireless network search see either ap when only one is active?

I wold recommend a single, simple consumer wireless router, dlink or netgear maybe, as they have seemed a bit more straight forward to me than the trendnet faqs I pulled up. If the investment is sunk, trying the above may help narrow the problem.
