Summary: I bought this about 4 weeks ago and haven't had a problem yet. I don't know what the other reviewers are talking about, except sound like they don't understand the difference between an Access Point and a Router. I am using this with a 8-Port Desktop Switch & a Wireless Router. I bought this on my previous experience with Linksys, the strength of reviews from PC World & others, and a couple of friends that work with Wireless Networks on a daily basis.
Summary: I'm not sure why other people are having problems with this access point. With the the latest firmware (as of 06/2008) the access points are stable and run for many months without crashing. I've configured 7 of these to cover a 100,000 square foot warehouse with the AP's suspended from the ceiling.
Summary: I read the prior reviews but went ahead and bought this on the advise of a friend who intalls wireless networks for a living and he uses this access point a lot. I am completly pleased with this Linksys product. When you plan to use it for what it is designed for, an Access point, and don't have any notions that it is anything more, it chugs right along. I ran CAT 6 cable, (keeping under 300 meters total length) and used the AC adaptor supplied to power the unit.
