I have an Edimax Wireless adapter that uses the rtl8192cu driver. I followed the instructions provided in the post: NETIS WF2120 Wifi Adapter Drops Signal Within Seconds
I even went as far as changing the command provided by HackerBaloo
"This worked fine in 15.10 today, I just had to change to : sudo dkms install 8192cu/1.10"
I had no way of connecting with an ethernet cable, so I downloaded all of the packages while my other adapter was plugged in. I then unplugged all of my wireless adapters before performing any of the dkms commands.
Upon rebooting; however, My adapter no longer functions at all. I had to un-blacklist the driver to get it to function, albeit the same unstable way,as before.
I had followed these instructions on a previous install of Ubuntu MATE 15.04, and it all went off without a hitch. It nearly tripled my up/download speeds and maintained a connection.
I further tried to do the same install as the post on a separate installation of 15.04, and I was unable to use the command
sudo dkms install 8192cu/1.9
I recieve this output on both machines:
Error! Could not find module source directory.
Directory: /usr/src/8192cu-1.9 does not exist.
I understand this process should work I'm just not sure where it is going wrong. Any assistance would be greatly appreciated.

sudo dkms install 8192cu/1.10
. Apparently, the package version has changed in dkms.conf.sudo modprobe 8192cu
help? Can you add the output oflsmod
to the question. It looks like the module may not be loaded.sudo dkms add ./rtl8192cu-fixes
. The last command is also redundant.
