Summary: When it is working, it works at 300mbs like advertised but almost daily while I'm using it, it just willshut itself off as if I unplugged it, and it's nothing that the computer settings has to do with it, it's for sure a dud from the factory Didn't last long so only gets 2 stars
Extremely poor results when used with Belkin Play Max
30 April 2013
Summary: These comments apply to using the Belkin Play Max Router with the Belkin Play Wireless dual band USB Adapter (F7D4101). After wasting 7-8 hours messing around with this router it still had absolutely no range on either 2.4 or 5Ghz bands. Both bands start dropping off at 20' even in an open room. Going into the next room or up a short open staircase and I was quickly out of range or this router. Way less range then my old Linksys WRT54GX router.
Summary: I had trouble receiving an adequate signal on my laptop when at any distance over about 20 feet from my AT&T "2 wire" router/modem. The Belkin adapter now gives me a range of almost 100'. I bought the device with some reservation but thought I'd try it. I'm impressed. Also highly satisfied.
Summary: This piece of crap not only has problems working with the N600 HD a Belkin product, but it is continually hosing up. You have to disable, wait, and then enable this thing all of the time to get to work. Anytime you re-boot your laptop, close the lid to move to another room, you have to either unplug the adapter or go though the disable, enable thing. Save your money go with something else.
