Dear Forum,

Please help. Since I've stuck with this problem.

Biggest Latvian ISP provided new router MikroTik 5G in exchange of old TP-Link router, provided by them also.

So the main problem is, when I've had all my devices from TP-Link, I've could just click on button WPS on all my devices and it worked perfectly, but right now it cannot be done, since this feature are available if all devices are from one manufacturer.

Right now, MikroTik are pre-configured by ISP (ethernet ports, WLans, IP addresses, DHCP pool and DHCP server on it), but I've changed couple of things:

*Disabled MAC filtering

*Disabled Firewall (temporary)

*Disabled Access Control and Access Lists.

*TP-Link extenders were resetted before new topology. 

* Mode were selected as extender not AP and done quick setup.

* After that, extender appeared with my SSID in WiFi list 2.4Ghz and 5Ghz, but when I trying to connect to them, it tells "Connected, but no internet" - MikroTik recognizing the extender in pool and providing IP address. 

** Extenders are working fine, with other AP.

 Tried the hints from this articles, unfortunately didn't helped :

The Mikrotik working fine, all websites are working, when you are connecting directly without extender.

I will really appeciate any help, if you have encountered this kind of problem or similar.

Thank you in advance.
