After today's firmware upgrade, wired devices no longer connect to router
I ran a firmware upgrade today and now none of my wired devices connect to the Main Deco. I upgraded firmware today based on notification from app and it automatically selected the firmware version. I did not download from website. We also had a 10 minute power outtage earlier in the day.
I have 3 Version 1 M5s that I have had for over 6 months and added 2 more this week that are version 3. All but the Garage were ethernet backhauled thru my wired home network. My Main Deco has one ethernet cable to my AT&T modem and a second to a switch that in turn distributes thru my entire wired network. Now, all of the others connect to Main Deco thru Wifi even though they are all still hardwired into my home network.
I found a thread on Home Assistant forum that seems to describe my situation in that the Main Deco doesn't know which ethernet port is WAN and which is LAN. He talked to tech support and they told him some code to enter but the OP didn't bother sharing that code. Unfortunately, this system won't allow me to share external links.
Any suggestions?
