I recently purchased a refurbished business level desktop to replace a damaged laptop. They do not come with a wifi card. I decided to get an inexpensive usb wifi adapter to hold me over until I could run ethernet. I wanted to get the maximum speed of a wired connection. The features/price ratio on this adapter sounded quite good. Shipping from California to Florida was prompt and installation was so easy even a politician could do it right. I just popped it in an open usb port, entered the wifi password and voila, I’m running! I did not even need the disk or instructions. I’m now getting three times the speed of my old laptop and rethinking the whole ethernet concept.
The only negative: It came in one of those Kevlar-reinforced sealed plastic protective wraps. I almost had to break out the Sawzall® to get to the adapter.
I tested this device on a small form-factor PC which had an internal wifi card capable of only hooking into 2.4Ghz networks. I expected this device to increase bandwidth to my 3-radio Wifi router, but it reduced significantly. Tested back to back I was able to pull down about 27Gbps on the old card and 5-7 Gbps on the new one connected to a 5GHz radio. I tried it on a different PC and the same result was attained. 2 stars as it works but its performance was disappointing. You get what you pay for I guess...
The built-in wireless adapter in my Dell laptop could not access the AC 5Ghz band of my wifi router. I ordered an AC600 Wireless Dual Band USB Adapter that arrived within a few days of my ordering date. The package contained the adapter, a driver diskette, and easy to follow written insallation instructions. It was up and running within a few minutes delivering very high download and upload speeds. I am extrenely happy with this purchase and would highly recommend this adapter.
