Good reception, especially with USB extension cable,
Verified Purchase(What is this?)
This review is from: TP-LINK TL-WN722N 150Mbps High Gain Wireless USB Adapter (Personal Computers)
I've used one of these for about a year and six months. It has served me well, and I've used it on Windows 7 64-bit, and Linux Mint 13 Maya 64-bit, both on the same desktop computer. I just ordered another one for my laptop.
I advise getting a USB extension lead when using one of these. Wifi transmission rates get iffy, especially when reception is bad, since the signal is digital, and if a certain threshold in signal quality is reached, almost no data can get through at all. An extra dBm or two on signal strength makes all the difference.
I also advise using a program like Inssider (iwScanner on Linux) to measure exact wifi signal strength and how other wifi networks in the area might be affecting your network. The more densely populated area you live in, the more important this is. On that note, looking out for equipment that can use Channel 13 (legal in the UK) is a good idea, since most of your neighbours will be using Channels 1 to 11. This dongle can do Channel 13.
edit: Better than using Inssider on a desktop PC (if you don't have a laptop to move around) would be to use a smartphone and walk around your house to see which networks of your neighbours are using which channels more. There are many free/open source 'wardriving' apps designed for precise mapping but which can be used to get only the channels of networks.
