I’ve got a Flint 3 and a Slate 7. When at home, I put the Slate 7 in AP mode and connect it to the Flit 3 via a MoCA adapter. I am pretty sure that all of this time I had been using the WAN port to make that connection. As in from a LAN port on the Flint 3 to the WAN port on the Slate 7 (I spell this out because I could use a sanity check on this for reasons that should become more clear as the post goes on. That is the intended way to connect when in AP mode, yes?) I’ve also been using the Slate 7’s LAN port to connect an old Hue bridge.
However, 2 days ago, the Slate 7 stopped having an internet connection and seemingly stopped giving any kind of connection to the Hue bridge. After messing with it, I was only able to get the internet connection back by plugging the connection cable into the LAN port. After doing this, the WiFi work fine, but the WAN port does not seem to be sharing the connection with the Hue bridge or a laptop I connected to it. I also connected the Slate 7 directly to the Flint 3 (as in no MoCA) and directly to the modem. In all cases, it only responded to having the connection in the LAN port. I also reverted back to router mode, then tried to go back to AP Mode without a cable connected and got the message that I need a connection in the WAN port. I connected to the WAN port and got the message again. I then connected to the LAN port and it then went into AP mode.
Does this sound like a broken WAN port to anyone else? Does the LAN port somehow know to take on WAN duties if the real WAN port dies? Also, I have not changed the fiction of the ports (although I don’t think that applies in AP mode anyway) and I have done a reset while trying to fix this. I will also point out that this happened the same day that I updated the Flint 3 to v4.9. I don’t think that’s actually related, but thought I’d mention it just in case. The Slate 7 is on v4.8.3
