Harshal Patil's blog Attempt

Recently got tp-link T3u mini wifi adapter   but as usual ubuntu did not have its drivers. So executed following commands and it worked perfectly.  cd /opt   git clone https://github.com/cilynx/rtl88x2bu.git   cd rtl88x2bu VER=$(sed -n 's/\PACKAGE_VERSION="\(.*\)"/\1/p' dkms.conf) 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

 Typically, if you dont have sudo and "gain" sudo access, you cant just add yourself to sudo group. In that scenario, we need to reboot in "advanced mode" and gain access to root shell. Once in, you can have following :  $ sudo cat /etc/sudoers.d/hpatil  hpatil ALL=(ALL) ALL and then we will have sudo access.
