I have seen many people report wifi connection problems after upgrading to kernel 4.9.x, especially with Realtek wifi chipsets..
I have managed to find a solution, thanks to thamer from Github..
https://github.com/Mange/rtl8192eu-linu ... /issues/18
Actually this is a driver issue.. The 4.9.x kernel for some reason is unable to use the correct 8192eu driver.. instead it is using the rtl8xxxu driver..
If you run "lshw -c network" from a root terminal, you can clearly see it is using a different 81xx driver..
So to solve this:
A.
Open "etc/modules" from a file manager (Nautilus, PcManfm, etc..) as root..
The "modules" file just contains a single entry "loop".. Add an entry "8192eu" before the loop as shown below:
What this does is manually pre-loads the 8192eu module during boot..
B.
Recompile the driver using "make && make install" from a root terminal and reboot..
Viola!! You'll have the driver working again.. I have checked this multiple times and have been satisfied this works every time..
C.
Actually, I have put together a tutorial for new users or people looking for detailed information on how to compile the Github driver..

Hope this helps..
