EX6120 connected, but no internet

My two EX6120 wif extenders stopped working after I changed router to ASUS RT-AC88U

AFter a factory reset and latest firware update . I can connect to the Extender, but No Internet

I checked PC ipconfig, it got default gateway 192.168.1.250. When I assign static IP and static gateway 192.168.1.1 everything works on PC. So, it looks like the extender assigns wrong default gateway to connected PC

And strange thing 2 of my extenders do not work...  is there is a way to fix it?

In hope if it can help somebody one day, posting my answer

The ASUS router RT-AC88U have weird feature "Airtime Fairness", set it to DISABLED

It is on the Wireless>Professional settings section. Worked after that for me.  Router reboot no required.

The feature purpose to increase router range, but caused problem to my extenders and wireless printer
