Installing AC1200 Dual-Band USB 3.0 Wifi Adapter (not A6210)

[robertcull1]

For Ubuntu 16.04 LTS

Apparently this is not the model A6210 (it doesn't look like it):

Hi. Thanks for getting back to me.

Here's a newer version that I got from the page of that link:

https://github.com/cilynx/rtl88x2BU_...X20171012-5044

I am a noob to github and I have no idea where to start. Can you give me a hint how to take it from there?

I am a noob to github and I have no idea where to start. Can you give me a hint how to take it from there?

We were all noobs at one time, even Linus Torvalds and even old Chili!

With a working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:

sudo apt-get update
sudo apt-get install build-essential git
git clone https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.2.4.4_25643.20171212_COEX20171012-5044.git
cd rtl88x2BU_WiFi_linux_v5.2.4.4_25643.20171212_COEX20171012-5044
VER=$(cat ./version)
sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER}
sudo dkms add -m rtl88x2bu -v ${VER}
sudo dkms build -m rtl88x2bu -v ${VER}
sudo dkms install -m rtl88x2bu -v ${VER}
sudo modprobe 88x2bu

You may safely copy and paste each command, one at a time, from this reply right into the terminal.

You should be all set.

[robertcull1]

Thanks for the encouragement.

There may have been some trouble with the last two commands:

robert@T61n2:~/rtl88x2BU_WiFi_linux_v5.2.4.4_25643.20171212_COEX2 0171012-5044$ sudo dkms build -m rtl88x2bu -v ${VER}
Module rtl88x2bu/5.2.4.4 already built for kernel 4.4.0-128-generic/4
robert@T61n2:~/rtl88x2BU_WiFi_linux_v5.2.4.4_25643.20171212_COEX2 0171012-5044$ sudo modprobe 88x2bu
modprobe: FATAL: Module 88x2bu not found in directory /lib/modules/4.4.0-128-generic

The adapter is still not presenting me with any networks to connect to.

[robertcull1]

I tried the last two commands with the adapter plugged in:

robert@T61n2:~/rtl88x2BU_WiFi_linux_v5.2.4.4_25643.20171212_COEX20171012-5044$ sudo dkms install -m rtl88x2bu -v ${VER}

88x2bu:
Running module version sanity check.

   - No original module exists within this kernel
 - Installation
   - Installing to /lib/modules/4.4.0-128-generic/updates/dkms/

depmod..........

DKMS: install completed.
robert@T61n2:~/rtl88x2BU_WiFi_linux_v5.2.4.4_25643.20171212_COEX20171012-5044$ sudo modprobe 88x2bu
robert@T61n2:~/rtl88x2BU_WiFi_linux_v5.2.4.4_25643.20171212_COEX20171012-5044$

Still I am not presented with any networks to connect to.

[robertcull1]

For some reason after about 5 minutes I was presented with networks to connect to. Now it works.

Thanks guys!

Awesome! Glad it’s working. Have fun.
