I bought it on sale, worth every penny!

Easy to install without any issues, it took maybe 15 minutes to install; I have Internet 150 at home, with 2.4G connection I would be lucky if I would get 30-35M on speed test; With this adapter on 5G connection I am consistently getting 150-155M

None so far

Stop looking. This is the one you want. Price is great. Works perfectly, discrete design. You won't find one better for what you pay.

I purchased this product as I was anxious to utilize the 5 GHZ band on my router. The 2.4 GHZ was way too crowded with over 28 routers in use in my immediate area. One of our laptop computers does NOT receive the 5 GHZ frequency on its wireless card. So this seemed the easy way to go.

It worked OK for about 2 months but didn't actually out perform a 2.4 GHz adapter we were told would be significantly slower. It lasted all of 4 months in use and just died. So wow, just wow.

When used as my WIFI device, it allowed the FULL 100 mbps speed; while my built in WIFI receiver that came with my laptop purchased in 2009; would only capture a speed of 20 mbps. I am pleased with the "D-Link DWA-171 Wireless AC Dual Band USB Adapter"; that exhibits no loss in speed.

I got this to replace a faulty wifi card in my laptop. Works like a charm. Best part is, I can use it with my desktop at home without using the ethernet cable. Although it is a little on the expensive side, it works like a charm and its great.

Working great so far even through a concrete block wall. Using with a dual-frequency router. Install routine needs some work, but got it working with the help of their tech support.

I had to move my computer desk to other room, due to a new baby. I wasn't sure if that thing is going to handle the job, as I download a lot, and playing on-line. I get download speed on my torrents exactly the same as I use to on cable, and streaming videos is no problem.

After some remote access help from a friend on my laptop, he suggested after upgrading to Windows 10 my internet adaptor was not recognised or working. He advised me to get a d-link. All working now.
