I have a Mofi 3500-3GN ver. 2 rev. 2 (which the company ships with OpenWrt-based but customized firmware, their version "9.2 std" somewhat based on Barrier Breaker r36346, kernel 3.3.8).
When upgrading from the company-provided firmware to OpenWrt 18.06.1, I thought the WAN stopped working, but in fact I needed to move my WAN cable to the first physical LAN port and then it behaves fairly normally.
(I upgraded the firmware with the following two .bin files)
- How can I fix this manually so WAN functionality is on the physical WAN port?
- Where is this controlled in the build process, hardware profiles, etc so that it will be corrected for other users in future releases?
(I have git installed and have fetched and (for other reasons) built my own copy of 18.06.1)
