A good price and good connectivity. Works well with Ubuntu.
Can't think of any. I think I needed to install the driver for Windows 7.
A cheap wifi usb adapter that allows my computer to connect to my router (through the floor) upstairs. Works well with a 1m extension and an aluminum pie plate to boost the signal.

Cheap, Windows auto recognizes, fair range, plug and play is great can transfer from machine to machine easily.
Not easy to set up in Linux
Good value for $15, easy to set up in Windows, wish it was easier to get Linux to work with it, not impossible though. Fair range, nothing special but nothing to complain about either.

Experience: 1 Weeks


- price
- reliable connnection
- none
For the price this is a very reliable and stable product. Build quality is average but the performance of this little usb adapter is good. Didn't have any issue with this adapter in Windows 7.

Experience: 2 Months


very easy to setup and install
signals a bit weak through walls and not always stable
overall its a good product for the price

Experience: 2 Days


Inexpensive, good value
None that I can think of
Downloaded the drivers from their site. Set up a computer in 2 minutes. Great signal through walls and seems stable enough.

Experience: 1 Days


works fine, install automatically with win 7
none apart the one 1 week shippinh
works fine, install automatically with win 7.

Experience: 1 Days


It works and doesn't need drivers on win7-64bit
You will lose the cap
It automatically installs with Windows built-in driver even on Win7 - 64bit.

NCIX apparently want me to write more than 30words to review the fact that it seems to fit into a USB port and has a reasonably complete implementation of the 801.11g specification. All that really matters is that it's the cheapest device and the drivers work!

Experience: 8 Days


Works right off the box. No connector software required!
This is my first time purchasing a TP-Link product and I am absolutely pleased with this product. I used to own D-Link hardware and deal with my share of connector software issues and incompatibility. Now this TP-Link product is plug-and-play friendly, has no connector software or gimmicks, works with all versions of windows from XP to Win7 and any brand of routers! Did I mention it might also be the cheapest wifi card on the market?! I will absolutely buy from TP-Link again!!
**5 Stars product!!**

Works well
free phone support
none that I have found
Phone support
Inexpensive and works!
What more do you want? ;)

I did have one problem that took me a few days to figure out and the person I talked to on the phone was difficult for me to understand... but it was a free callTurned out zone alarm was somehow blocking the adapter from working. I tried to find a work around but no success. I had to un-install ZA for the adapter to work.

Experience: 10 Days


it works fine. windows 7 compatible
It works. and that's all you should care about. really not much to say. it has a windows 7 compatible driver so don't worry about that. the price is good, too, compared to some pci cards. besides, with the prevalence of Dual dual-slot graphic cards, PCI slots can be precious.
