good reception, always gives me max signal strength
won't last more than an hour before it stops working
I guess you get what you paid for. I personally think I am a guy with a lot of patience, but when I keep having to re-download the same thing off the internet repeatedly because my adapter continuously stop working, I start to get annoyed. I'm already looking for a new adapter cuz this one ain't working for me... it did give me a good signal when it worked however. WHEN IT WORKED.

P.S. I believe people were saying not to download the useless utility disk? I however found I couldn't use it with out the disk. It could just be me, try it with out if you gonna buy it, then if it doesn't work don't be afraid to download the utility...

my advice: save your money, unless your downloading things under 2GB and can DL at least 1mb/s. This isn't worth the head ache. (the thing even decided to stop working while I was writing this review, not once, not twice, but THREE TIMES) internet troubleshooter or a computer restart usually fixes the adapter.

also this was meant to be a 2 star review...

- Strong, consistent speeds
- Low price
None at the moment
Bought 2 of these for my computers, and I have to say, they haven't let me down. They're great for regular downloading, and the price when price matched is fairly low. Transferring files through a network is slow however, but this adapter wasn't made for that anyways.

-good price for $21, was the cheapest wireless card at the time
-adjustable antennas which help a tiny bit sometimes
-seems pretty slow but i guess wireless is slow anyway
I never tried wireless on my computer before so I didn't really know what to expect. A little dissapointed in the slow speeds and occasional D/Cs but I guess you get what you pay for.

Fast, stable, good price
Driver Problems
I never dropped once using this card. I only dropped when my router blew out. Amazing speed, I am using it right now. Only problem is the driver, I never updated but been using link in the forum for 1 year now, no problems or conflicts.

Works Well with ralink drivers, cheap, reasonable signal strengh
Terrible drivers provided by asus. Single antenna
Needed a cheap wireless card and this fit the bill. Get the Ralink drivers before even bothering with the asus supplied ones if you are intending to use this under xp.

Asus quality
Decent reception
Works fine, installation/drivers went smooth. No problems, good affordable card. The signal strength is excellent and I get reasonable transfer speeds. Recommended.

Decent signal, good quality, nice price!
Haven't found any until now.
I installed the board on my system, I installed the drivers and let Windows (Windows 7) do the rest. It recognized my Wi-fi access point and connected smoothly. Works just like it should. I refrained installing the utility which came with the board because everyone kept saying how terrible it is and how it can screw up your network settings. Windows 7 handles everything that this useless app does so why bother using it?

Hardware and driver are working fine on my Vista system (32 bit).
By the way, I installed the driver off the CD which came with the card, and when I look at it through the Windows Device Manager, the Driver Provider is "ASUSTeK COMPUTER INC." but when you click the button to view Driver Details, the Provider is cited as "Ralink Technology, Corp". The File Version: is, which basically matches the Driver Version
Some other commenters have said things to the effect, "ignore the useless ASUS drivers and get Ralink". Hope this adds more confusion! :)
Here is the part I'm upset about. This comes with stupid utility; don't use it! Oh my god, when you run this program, it automatically connects to a router called "linksys" on channel 6, even though you already have a wireless network connection. I became very confused because I tried to go to to do something on my own Linksys, and, unbeknownst to me, I was actually talking to someone else's unsecured linksys which the ASUS program found through its default settings and behavior!!! I was not able to log in to this of course, and so I thought it was my own router that had been hijacked. Moreover, my net connection stopped working (since the ASUS utility messed up my default route through my router). I panicked and powered off my router, then reset and reconfigured the thing from scratch. Only some time later did I discover what had really been going on, when I reproduced the scenario by running that program. I wasted a good two hours on this, all together.
Fine product; just do not run, or even think about installing the idiotic, dangerous Windows utility it comes with.
Just install the driver, and operate the card through normal Windows networking.

Drivers found via Windows update  in Windows 7 x64.
Causes blue-screen of death occasionally
I bought one of these for my low profile HTPC.
As mentioned, the drivers from the included disk do not work, but after plugging in an Ethernet cable into the machine, it found drivers almost immediately.

Sometimes, this card causes Windows to have a blue screen of death. I wasn't aware that this problem still existed... A reboot should solve the problem. The blue screen of death only occurs when there is a lot of downloading/uploading activity (excessive torrenting), or your computer wakes from sleep and tries to re-establish a connection via the card.

Other than that nuisance, I haven't noticed a problem with this card.

x64 drivers
good reception
none so far
Does what it needs to do, no problem so far, receive signal in WPA2 encryption, has drivers for x64 drivers, and is pretty cheap what else would you want
