I have a USB wifi dongle that has the RTL8188eu chipset. It used to work without having to do anything (i.e. I could just plug it in, and away it would go).

While trying to install various other USB wifi dongles, I have somehow managed to delete the driver for this dongle (on my system, in /lib/modules/4.13.0-31-generic/kernel/drivers/staging/rtl8188eu).

I have tried to rebuild this (r8188eu.ko) by mimicking the steps I used to rebuild my btusb.ko (which also went missing):

• Downloading my kernel source from https://www.kernel.org/pub/linux/kernel/v4.x/
  


• Un-tarring it: tar -zxvf linux-4.13.tar.gz
  


• Changing in to the directory: cd ./linux-4.13/drivers/staging/rtl8188eu
  


• Building it: make -C /lib/modules/$(uname -r)/build M=$PWD modules
  

But I get this error:

[van@van-t470p:rtl8188eu]$ make -C /lib/modules/$(uname -r)/build M=$PWD modules
make: Entering directory '/usr/src/linux-headers-4.13.0-31-generic'

I also tried running make one directory level up:

• cd ..


• make -C /lib/modules/$(uname -r)/build M=$PWD modules

But this failed too:

Perhaps the Makefile parameters are different for wifi modules? Is there a way I can rebuild my missing r8188eu.ko, or do need to re-install the operating system?
