Hi!
After some months of work I decided to update system and after that my wifi adapter (RTL8188EUS) no more works. dmesg every second shows message "R8188EU: ERROR indicate disassoc", but firmware packet installed and kernel module r8188eu compiled.
Here is dmesg output:

Here is kernel config:

I'm not sure it's a bug, but before system update everything was work fine.

Please don't use pastebin.com for bugs, we need to preserve history.

Also, R8188EU is deprecated and replaced with rtl8xxxu driver in kernel 4.3+.

See if the new driver works for you.
Comment 2 Brian Evans (RETIRED) gentoo-dev 2016-10-20 17:58:02 UTC
Actually, 8188EU is under heavy development[1], maybe it's not ready quite yet.

I just tryed rtl8xxxu, unfortunately it doesn't work and even doesn't load during boot. It also doesn't work when I load it manually with modprobe.
Adapter is not broken, because in other distributives (Ubuntu 16.04 for example) in live boot it works with 8188EU
Comment 6 Jonas Stein gentoo-dev 2016-10-23 22:20:17 UTC
The reported problem does not look like an gentoo problem to me, but rather like a general problem with the kernel source and the hardware.

I suggest to try the following:
Check the kernel version in Ubuntu, where it worked, and save the kernel config
(http://superuser.com/questions/287371/obtain-kernel-config-from-currently-running-linux-system) 
Compile a Kernel with the same config and kernel version as it worked on Ubuntu before.

I do not expect that we can help you appropriate in this bug tracker and suggest to contact others on IRC, mailinglists or a forum about linux.

I will close the bug here, because I think it is not related to gentoo. 

Please reopen it and provide more details if I am wrong and good luck with the kernel.
