Data not getting through to stations


Hi.
I'm banging my head against the wall on this issue.
Data is not getting through to the stations. Stations are associating, passing 4-way handshake, sending DHCPDISCOVER to router, router responds with DHCPOFFER, I see the offer on wlp9s0 on router with wireshark, but stations doesn't receive it. Unfortunately I don't have wi-fi sniffer.
When it doesn't work, it doesn't work for hours, but sometimes out of sudden, without changing anything it starts working. It happens with all the stations, so the issue must be on router side. It can fail with one station, while working with another station at the same time. After some time the station that worked, may not work any more and the one that didn't work can become working. So it is really freaking mess.
Router config:
wlp9s0 - wireless interface.
Code:
lieta@lieta:~$ sudo brctl show

Wi-fi card is Asus PCE-AC51 with Realtek RTL8812AE Wi-fi chip. I've used original driver that came with Debian, compiled it from sources - same thing.
