Summary: I've been running one of these 24/7 for the last couple of years with zero trouble, excellent wireless range and performance. Being limited to one band or another but not both at one time is a minor drawback as is not being able to attach external antennas. Runs DD-WRT flawlessly. Runs cool and possibly the best Broadcom based Linksys ever. Has handy built in wall mounting feature which is something that should be on every router.
Summary: We've had a few of the Linksys routers and all of them have stopped working right after the warranty has expired. We bought this one in November of 2009 and it stopped working yesterday (Jan 4, 2011). We're probably going to get another one just like it so we don't have to reset all of the home computers or maybe upgrade to the E3000 (appears to be a slight improvement). When it works, it's great!
