Today I have updated Ubuntu version from 16.04 LTS to 18.04 LTS. After that Ubuntu doesn't recognized my Wi-Fi driver. Kindly support to solve this problem. Thank you.

vahe@vahe-Ubuntu:~/rtl8188eu$ lsusb

The driver have to be installed from sources
Open a terminal windows and go for it

sudo apt-get update
sudo apt-get install -y linux-headers-$(uname -r) build-essential git
git clone https://github.com/lwfinger/rtl8188eu
cd rtl8188eu
make all
sudo make install
sudo insmod 8188eu.ko

  • vahe@vahe-Ubuntu:~/rtl8188eu$ sudo insmod 8188eu.ko

    insmod: ERROR: could not insert module 8188eu.ko: Invalid module format.

    I have got such error!

    I don't believe 8188eu covers his 148f:7601 device, @Pareri Check: modinfo 8188eu | grep 7601 – chili555 Jun 19 '18 at 12:59
  • It looks like a Mediatek. – Pilot6 Jun 19 '18 at 16:21

    This driver works, but it caused my speed to drop even lower than it was before. It's a linux driver issue, when using my phone as wifi dongle, my speed is 5x though it's connected to the same router. – CoderGuy123 Jun 26 '20 at 13:48
