We just bought this half height pci-e card for one of our guest computers in our clubhouse after suddenly having wifi issues after upgrading Lubuntu to 17.04. We decided it was time to break free from Ubuntu’s constant breaking of of our equipment after updating so we decided it was time to make the jump to Antergos (Mate desktop).
While installing Antergos we realized the little stupid “thumbnail” wifi adapter we were using (EDiMAX 802.11N Nano USB2.0) was cutting in & out - either because it was defective or it’s simply because our router is in the next building over though a brick wall - preventing the Antergos installer from downloading the new packages during the install.
At first we though the Antergos installer had broken, but we realized it was because it wasn’t able to connect to the Internet even though it said it was connected, which was very frustrating to say the least. Also, we’re not sure if it was a driver issue because the Antregos live session was reporting a strong signal strength.
Anyways, we went to our local computer store and the guy suggested one of these: http://www.shopsws.com/networking/adapters/tl-wn881nd.html (TP-LINK TL-WN881ND Wireless N300 PCI Express Adapter), he said was based on some “broadcom” chip which a lot of his customers were reporting works great with Linux.
After installing this new card the wifi was finally working beautifully and we were able to complete the Antregos install process and get our clubhouse computer working great once again (no thanks to Ubuntu).
