FS#4090 - No configuration from ISP on Asus RT-AC85P

Supply the following if possible:
- Device problem occurs on Asus RT-AC85P
- Software versions of OpenWrt/LEDE release, packages, etc.: 21.02
- Steps to reproduce

 After installing latest released OpenWrt 21.02 to AC85P I found it is not able to get network configuration from ISP - WAN interface has no IP etc. 

Some additional info:

  • My old TL-WR1043ND with OpenWrt 19.07 works good with my ISP.
  • My desktop machine and all my several laptops works good with my ISP (connecting to is directly by cable).
  • RT-AC85P with stock firmware works good with my ISP; it is getting network config from ISP.

I made a call to my ISP support informing them my router not able to get network config on what they answered “my router doesn’t sends its MAC address”.

An appropriate forum thread: https://forum.openwrt.org/t/no-configuration-from-isp-on-asus-rt-ac85p/108056/12

And recently from suggestion from some guy on 4pda forum I found a workaround which works. After setting WAN to 100 mbit:

ethtool -s wan speed 100 duplex full autoneg on

it is immediately received config from ISP. It is definitely a bug!

I can confirm. Also if connect ISP cable to the lan - same situation. For some reason driver incorrectly detect connection speed for the ISP cable. With PC it correctly detected 100 and 1000 mbit. If connect ISP cable directly to PC(which have 1gbit eth) - all correct, have 100mbit link.
