Device: Belkin F9K1115 v2
Software version: OpenWrt 18.06.0-rc1, LEDE after r3466-f6907dc

Unable to use wan port on any new software version (last known working LEDE version is r3466-f6907dc).
DHCP is not getting ip address. After setting up static ip address there is no network communication.

There were 3675 commits between r3466-f6907dc and OpenWrt 18.06.0-rc1. So far I wasn't able to spot anything suspicious and it's quite unlikely that anyone will be able to find the single offending commit in the 3675 commits.

Your best bet is to do a git bisect between f6907dc (r3466 good) and 367513f64a1e597e00e7bc9cf73866533f668482c4fa (OpenWrt 18.06.0-rc1 bad).

Wan port is not working after this commit: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=967b6be118e3217e8d6a28df9c615d3255e7b1ae

OpenWrt 18.06.0-rc2 compiled without this changes in ar8327 is working correctly.

I can confirm reverting that commit fixes the wan port for me.

Thanks for doing the bisect! Looking at the mentioned patch, the commit message says:

Finally, AR8327 reserved register fixups are disabled for the AR8337.

But the ar8327_phy_fixup is removed from the ar8327_chip struct instead of the ar8337_chip one. Either the commit message is wrong or the wrong line is removed.

Would any of you please test if the attached patch fixes the issues.

hi I have updated the firmware to 18.6, I do not have DHCP working. Resetting does not solve the problem. As with 17.01.5. How was it possible to release the final one with a critical bug?

Quite simple, no developer has access to the hardware and it was not reported in the rc phase or in the prior months.
