Query: Very flakey device, works...sometimes.

Let me start by saying that I have the version 2.2 of this device, so hopefully the later versions fixed some serious problems.This device works, some of the time. I used it about 30 feet from a Linksys WAP11 device, and it gave me 100% signal strength. Throughout the day, that signal strength would jump radically from 100% to 10% to 0% to 50%. It is extremely flakey, and very very frustrating.I replaced it with a Linksys WET11 device which has a bigger antenna, and so far has worked like a charm 100% of the time. I am in love with the WET11. It's one-time configuration can be daunting to the layman, but once configured, you can connect it to any ethernet equipped device, and not need any other drivers.Do not get the WUSB11 if you can afford the WET11.
