4 out of 5 eggsWorks

Pros: Well it works. Able to connect to my network without a hitch, and the speeds are good.

Cons: Can't install the Utility program on a 64-Bit OS, but I doubt I would have needed it anyway. Has a big green led on the front, that constantly flashes telling you it's on/connected (maybe a pro for you).

Other Thoughts: I was a little reluctant to buy this because it was relatively new and had no reviews. I got it to replace my D-Link DWL-G122, which failed after about 3 months on my Windows 7 machine (finding drivers were a pain in my bottom, so I bought this). Happy wit the purchase

5 out of 5 eggsBest value for a wireless adapter

Pros: It's been working perfectly since I bought it, no problems installing, and no hiccups in my connection.

Cons: Windows tells me it's operating at only 65 mbps but it's not like you'll ever get a speed that high in the first place.

Other Thoughts: $14 for a great adapter, you can't go wrong.

2 out of 5 eggsEasy Install, Unacceptable Performance

Pros: So far, I've only used this adapter on three Windows 7 computers. The installation is incredibly simple (point to driver folder, watch it install). No driver or system crashes to date.

Cons: Performance issues on each computer it's been put to use on. It's main life is on a media center computer, connected with a USB extension cable to allow it clearance of the obvious obstacles; distance is ~20-30 feet from the router and one wall (sheetrock) in the path. It's dual use for temporary use on test rigs built in my garage; distance is ~30-40 feet from the router with a door and some wall segments in the path. The device always shows a good connection (54Mb), but the actual throughput will frequent drop below 1Mb/s or stall completely, then jump back to normal. The best speed I've tested is ~15Mb/s on my local network. Other wireless devices don't seem to suffer this same fate.

Other Thoughts: This device is connecting to an AT&T 3800HGB-B Uverse router, so my testing has been limited to 54Mb.

Manufacturer Response:

Dear customer,

This is Shania from TP-LINK Support Team.

We sincerely apologize for any inconvenience caused by our product.

As you know, the slow speed could be caused by many factors, like the interference, barrier, high-power electricity, etc. we suggest you install the latest driver for this adapter from ours or the chipset manufacturer’s website and go to your wireless router settings, change the channel and set a better encryption.

If you need any help, please feel free to contact our technical support at 866-225-8139. Thank you.

Have a nice day!

Best Regards!
TP-LINK Support Team

3 out of 5 eggsHad some issues

Pros: Installed easy enough

Packaging was nice and the install CD had the appropriate drivers.

Cons: Had HUGE issues with this adapter and my Microsoft wireless 5000 mouse and keyboard. Every 10-15 seconds my mouse pointer would lag or stutter across the screen. I check hardware monitors and it should almost 0 CPU usage so I know my processor (FX 8120) was being bogged down.

I tried for 2 days searching online for a fix or known issue and came up with nothing. I tried multiple drivers and configurations and even used an extension cable to see if maybe they were getting RF interference from one another.

The only thing that ended up working was unplugging this adapter. Once I did that everything worked fine but then I of course had no connection.

I'm still giving this 3 eggs because it might have been some WEIRD thing going on with my new build but for the life of me I could not figure out what it was. Someone else might have better luck but if you end up like me the only thing to do is take it back.

Other Thoughts: I ended up buying an ASUS PCI-E 1x wireless card and once installed it worked great with almost 0 issues. If you have a similar issue like mine I would recommend going that route. It cost 2 as much but it cured my wireless headache and I don't mind paying the difference.

1 out of 5 eggsDisappointment

Pros: Cheap price, High hopes

Cons: Constant crashing, crashed hopes

Other Thoughts: I have a 32 bit Vista OS and this stuff will just not budge. Every single time I try to install the driver the blue screen pays me a visit. This stuff freaks me out and I'll be darned If I'll let this small piece of thing destroy my computer. Definitely returning it right away

5 out of 5 eggsGreat little adapter

Pros: We have been carrying TP Link products in our shop for quite some time now. We sell and internally utilize their routers, and adapters. These adapters are fast and reliable. I have probably used 30 of them by this point and I have never had one go bad or be returned. They are AWESOME. I also like the feature where you can install the driver only and not their interface software so users can not get confused.

Cons: None at all
