Summary: My son's grandmother gave him her old computer when she upgraded, but it didn't have Wi-Fi. I did some research and found the Edimax EW-7811. It was super easy to install... you just plug is into the back of the computer, slip in the disc, and withon 2-3 minutes you are up and running on Wi-Fi. I'd recommend this all-day, every-day.
Summary: I bought this USB WiFi Adapter for my laptop whose internal WiFi adapter doesn't work any more. Price is the best what you can get with free ship to Walmart store. It comes with an installation CD, that has a very good software to configure the WiFi in seconds. However, looks like it is not giving the best speed at times compared to my other laptops with built-in wi-fi.
Summary: All I had to do was disable my built-in wireless card and plug this one into my USB port. It installed and found my router automatically. Entered the security key and was connected to the Internet in 60 seconds, with 4/5 bars. Up from 2/3 bars.
Summary: I bought this wireless adapter because the wireless card on my laptop stopped working. As soon as it arrived I plugged it into my laptop's USB port and installed the software from the included installation CD. In minutes I was surfing the web with faster speeds than the original wireless card! Now I use it on my netbook as well because the browsing speed is so much faster. This is a great little adapter and I would highly recommend it.
Summary: I had problems with the download speed initially - upload was fine. I figured it was a driver issue. I uninstalled the driver (Windows 8) and asked the Device Manager to find the latest driver for me. Worked phenomenally after that. That tiny thing packs a mighty signal!
Summary: I attempted to install and use this on my three computers using the wireless modem supplied by CenturyLink. The one using XP seeemed to work ok, but then began acting up. The laptop Windows 7 seemed to install ok, but it pulled in no signal when plugged directly into the machine. It worked better when I put it on a 10 foot usb extension wire. Still it was not as good as my old direct plugin LinkSys for that computer.
