Summary: I had picked this USB adapter because D-Link provides Mac OS drivers via the support site. They don't work. Performance is good but the Macbook kept crashing every 10min. I've now got an ASUS 802.11ac stick for my Macbook Pro and it works fine.
Summary: I bought this a few weeks ago, and it's been nothing but problems since. I have a dlink router, and this thing constantly loses connection with it. The router is on the 1st floor, this adapter on the 2nd, but the straight line distance is only about 20 feet. My other adapters work better. When it's connected, it's very fast, but it CONSTANTLY drops.
Summary: I read a lot about this unit before I bought it but none of the negative reviews affected my reason for purchasing. I just wanted to boost my wireless reception for my PLEX media player and I own a D-Link Dual Ban Router...I thought this could only make things better. Contrary to other reviews, the software installation was trouble-free. The setup wasn't bad, but I'm fairly tech savvy..
Summary: I use with a Dlink AC 1750 and it performs great. No real install problems. Using the adapter on a home theater PC for streaming to internet base content as well and recorded TV. I use the 5GHz band for media streaming, and the 2.4GHz band for routine networking and internet access for everything else. No complaints.
Excerpt: I have read the other reviews and they were mixed. But I had no problem downloading and installing the drivers from DLink's website. I was up and running in less than 10 minutes, with Windows 8.1 OS. I bought it for use with my HP Pavilion 10 TS Notebook PC. The installed wireless adapter was slow opening webpages (I stopped all background processes and disabled extraneous apps) and very laggy running YouTube videos and Netflix.
Summary: I bought this unit to use with the Linksys AC wireless router. The problem is that the unit is over-sized and will not plug directly into a notebook's USB port, without obscuring the next USB port. You MUST use the included dongle cable and socket if you don't want to loose the use of the second USB port. (Most notebooks place USB ports close beside each other, and you usually only have 2.
