Hello.
After installing latest released OpenWrt to AC85P I found it is not able to get network configuration from ISP - WAN interface has not IP etc. Allthough all interfaces including WAN is UP as showed by IP addr command. I tried also applying static to WAN but this not helped: config was applied but no connection to Internet. Any ideas?
P.S. Yes, it worked fine with OEM firmware.

If you use a cable modem, have you tried turning it off for a few minutes?
To confirm the WAN port is working, plug the Openwrt router into the LAN port of any router, and check the WAN interface acquires an IP address from the router.
Someone else may be able to help once we know the ISP and details of the external modem.
My ISP is Triolan. But now I am not able to enter router's web-interface at all. Router not gives my machine any config. Seems it is bricked. And this happened after I reset MAC-addresses on the appropriate tab of Interfaces configuration. 8( I tried reset button but not helped.
If holding down Reset for 10 sec after switching ON power makes power led flashing slowly but I am not able to open 192.168.1.1 in browser, no ping to it also.
Unfortunately Asus Restoration Utility is only for Windows while I am using Linux. Will think what to do and where to get windows.
P.S. I can't find firmware restoration tool on RT-AC85P homepage. o_O
Choose 'Windows 10' in previous Asus web page link and click 'Show All' to reveal restoration tool

ASUS Firmware Restoration version 2.1.0.2

Firmware Restoration is used on an ASUS Wireless Router that failed during its firmware upgrading process. It uploads the firmware that you specify.
Recently debricked with Asus firmware tool successfully (found an old HDD with windows on it). But I don't understand what to do now and why there was an issue getting network configuration from my ISP. With OEM firmware it works fine.
My ISP provides network configuration by DHCP. No authentication but MAC binding on ISP's web-page. It means I should open it's web-portal and manually enter MAC of my router's WAN-interface (or my machine's Ethernet-port).
I did not make it in time to check if WAN port receiving something from LAN-port of my old TP-Link. But I can try flashing an OpenWrt again. Just not sure how to do that best: by SSH (as first time) or by SFTP.
Recently checked. It receives the IP address from another router. I made a call to my ISP and they told me that my router doesn't send its MAC to them.
So...
My old TL-WR1043ND with OpenWrt 19.07 works good with ISP.
My desktop and other laptops works good with my ISP.
RT-AC85P with stock firmware works good with my ISP.
RT-AC85P with OpenWrt is not able to get network config from ISP.
...maybe the issue in OpenWrt ?
