Buggy Realtek8111E Sierra driver Ga-p67a-ud3-b3

[Chainer]

Hi guys! I've got a really weird problem here.
My rig: gigabyte Ga-p67a-ud3-b3
i2600
Samsung Evo 840ssd
I've made a clean install of Sierra 10.12.6
Applied multibeast, everything works. Network, sound, etc, expect for sleep.
But the problem is: my hackintoch is connected through Asus rt-n16 router. Whenever I turn the hackintoch on, all wireless clients, connected to my network, lose connection, and are unable to connect again, until I shut down the computer. The cable is not faulty, tested the same machine with win10, no problems. Kext for network was from multibeast, 2.0, I think. Unable to test with 2.2 version, as it's unsigned.
Any advice?

Seems i've figured out it by myself) using lnx2mac driver, no wi-fi drop so far))
Update: same story.. after half an hour, wifi connection drops for all devices. It's definitely not cable/router. I'm stuck(
