Forget the brand name, this is a Realtek RTL8811AU Wireless... LAN USB Network Adapter (or at least mine is). Out of the box and connected to my Windows 10 laptop or PC to my 150 Mbps Broadband, I got the same results: as expected upload speed but incredibly slow (2.5 to 3.7 Mbps) download speed on both bands. Attempting to install the drivers from the disk resulted in a message that I had the latest drivers already installed. Before giving up, I went to the Realtek website, then selected “Downloads” (top line) and then navigated through “Communications Network ICs, Wireless LAN ICs, WLAN NIC, USB” and finally, “Software”. I clicked on “Global” to download the file, unzipped it when the download was complete and then updated the driver on the adapter. SUCCESS. Now I get the same upload speeds as before, but my downloads speeds are now 57Mbps on the 2.4G band and 192 Mbps on the 5G band. Hope this information helps anyone dealing with the same issue.

Works well on Linux Mint. To inst...all the driver use this GitHub repo: morrownr/8821cu The speed (on the 5GHz band) is almost 10 times what it was with an old USB adapter.

I've bought and reviewed at least four other AC network adapter in... the last several months. Unfortunately, I’ve been disappointed in all of those products to date and returned them all (thanks to great return policy). I’ve been trying to upgrade a Rosewill N adapter that offered decent speeds, but wasn’t taking full advantage of may AC router network speeds. The purchase of the EDUP AC 600 adapter has finally allowed me to almost do that. I have a Linksys EA7500 router that’s capable of 1300 AC speeds as well as a RA6500 extender capable of 867 AC speeds, so the speeds promised from the EDUP AC 600 adapter are certainly possible on my network. While I have yet to achieve the promised 600 Mbps of the adapter, I’ve more doubled the speeds from the Rosewill N adapter at 144 Mbps up to about 325 Mbps for the EDUP AC adapter. Since I purchased it a couple of weeks ago, the EDUP adapter has been in constant use, with zero lost connections or downtime. I think that’s fairly remarkable since the adapter is one floor down and about 20 feet away from the router, and on the same floor, but about 30 feet away from the extender in a nearly 3,000 SQFT house. Recommend if you’re running windows 10 or 7 that you let windows search & install the drivers and that you use the windows WLAN management utility instead of the klunky Realtek utility on the disk. I’ve tried the EDUP on both a windows 10 desktop and a windows 7 HTPC with no issues. I’m pleased enough to buy a second one for use with a laptop in my son’s room.

If your computer doesn't have an inter...nal WLAN or Bluetooth card, then this is a good external substitute. It has everything that is needed and works as good as an internal WLAN or Bluetooth card.

I use Linux and the driver that ...comes with it doesn’t work. Found the correct driver and it was fantastic and welcomed surprise. It works great.
