ER605 v2 WAN down after OC200 firmware upgrade
Last night I upgraded my controller to the latest version, 5.13.30.20. Just as it was finishing up I lost my connection to the interwebs and it's been down ever since. My alerts is saying "[WAN] of ER605 is down" but when looking at the details for it I can see it has dial-up set to connected, IP and gateway are both set to the same 88.88.x.x address. Online detection is reporting offline, tho.
Also, on the dashboard I have 357 association failures (!), all of them from "blocked by access control" for some reason. But when I go to Insights -> Known clients -> Blocked the list is empty. I'm also seeing all 22 of my clients connected successfully.
I've checked that a direct connection between modem and PC is connecting to the internet, so it's not my ISP. I've also tried switching from the WAN port to the WAN/LAN1 - same result. Tried force provision on the router and of course unplugged and rebootet everything.
I'm all out of ideas here. It's almost as if upgrading my OC200 has bricked the ER605, despite both of them being responsive and more or less up and running. Anyone have any clue on how I can fix this?
