[SOLVED!] edimax EW-7822ULC usb wifi adapter linux driver

Post by FanOfLinux » Mon Jun 11, 2018 2:32 pm

Hi :

I have an edimax EW-7822ULC usb wifi adapter,
but when I plug it in on LM 18.3,
its linux driver was not automatically loaded.
Meaning I do not see it on the Network Settings
or Network Connections apps.

I can download and compile it from here: http://www.edimax.us/html/english/frames/b-download.htm

I rather not since I do not want to break LM 18.3 and the kernel I now have is:
$ uname -r
4.13.0-43-generic

and the manufacturer's downloaded driver only supports this kernel range:
Wireless AC1200 MU-MIMO USB 2.0 adapter for Linux kernel 2.6.24 - 4.7

Where else (or how) can I download a compile and tested driver that I can install for this
edimax EW-7822ULC usb wifi adapter on LM 18.3?

Thank you.

Just wondering...
What are the devices for Linux Foundation 3.0 (or 2.0) root hub?
