I am attempting to install drivers for my wifi adapter (Netgear Ac6120 Wifi Adapter)
The adapter shows up when I type 

$ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 003 Device 002: ID 154b:00ee PNY 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 0b05:17cb ASUSTek Computer, Inc. Broadcom BCM20702A0 Bluetooth
Bus 001 Device 005: ID 0846:9053 NetGear, Inc. 
Bus 001 Device 003: ID 258a:0001

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

After following these steps 
$ git clone https://github.com/jurobystricky/Netgear-A6210
$ cd netgear-a6210
$ make

I get this error 

export DBGFLAGS

What do I need to install or do to resolve this.
Thanks

After installing gcc and libelf-dev i get

After following the steps you mentioned i got an internal error but i wasn't able to catch what it was and it didn't show after restarting twice
The wifi adapter is showing up connecting to the wifi now so thank you for that

it does take a little long to connect (about a 1 to 1 1/2 minutes ), is that just how the adapter runs on linux/ something i'll have to accept?

  • You need to install, at least, gcc and libelf-dev and try again. –  Nov 15 '18 at 03:31
  • Have you tried doing what it tells you - ie. "please install libelf-dev, libelf-devel or elfutils-libelf-devel". – guiverc Nov 15 '18 at 03:31
  • I will get back to you regarding that in about 15 hours, i do not have access to the internet on my Ubuntu system at the moment – Alexander C Nov 15 '18 at 05:03
  • "it does take a little long to connect (about a 1 to 1 1/2 minutes ), is that just how the adapter runs on linux/ something i'll have to accept?" The original question, that your interface didn't show up, has been answered correctly, no? If it is now connecting but is slow, I think that is the subject for a new question. – chili555 Nov 16 '18 at 14:21
  • haha yes the original question has been answered. Thank you for everything – Alexander C Nov 17 '18 at 04:44

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 libelf-dev build-essential

Then try the 'make' step again.

EDIT: The git repository you are using hasn’t been updated in two years. It is incompatible with kernel version 4.15 and newer.

Now let’s install a better driver. Please download this file: https://github.com/kaduke/Netgear-A6210/archive/port-to-4.15.zip

Right-click it and select ‘Extract here.’ Now back to the terminal:

cd ~/Downloads/Netgear-A6210-port-to-4.15
make
sudo make install
sudo modprobe mt7662u_sta

Your wireless should now be working.

Please tell me how it proceeds; I will probably have one final step.
