Install IP Time USB Wifi Adapter driver for Ubuntu Linux
It’s not that hard… provided you know where to look.
First, find out the model ID by going
lsusb
You’ll get something like this, where “Realtek” is the chip manufacturer, which is usually the case for IPTime
Next, google the ID, it will take you to stack overflow, in my case, this answer
Which leads me to this repository
A few commands later…
cd rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959
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
And voila, it works even without a reboot
