I recently bought a similar, cheap USB Wifi device, no brand bit of a mystery but lsusb showing 0bda:f179 Realtek Semiconductor Corp. Apparently a Realtek RTL8188FTV Wireless 802.11n USB 2.0 - in case anyone's Googling.
I almost gave up installing after finding various Github driver patches, then finding MrEngman's mega-thread about installing various drivers. I've actually already ordered another cheap USB device through the post in case
I tried several ways to try and get MrEngman's drivers downloaded - from Dropbox, http://downloads.fars-robotics.net/
- but seemed to mostly get 'file or page not found'. However, your reply and commands on this post seem to have worked thanks! Still got to actually setup the wifi, but at least its recognised. Also thanks for the previous tip on upgrading the Pi to latest Linux. I only recently installed Raspbian Lite from an image.
sudo wget http://downloads.fars-robotics.net/wifi ... stall-wifi
sudo chmod +x /usr/bin/install-wifi
MrEngman - might I suggest you streamline your web page to not mention DropBox etc if that's out of date, and just link to your helpful install script? You also might like to embed HTML links to your driver images rather than the instructions to add each driver image to the end.
