Nothing. I’ve never updated the firmware. It shipped with the latest.
I haven’t tried creating another wireguard peer config but considering this config works everywhere else, I doubt that is the issue. I don’t have easy access to change the Pi4 WG config right now.
My initial experience with the MT1300 was so good I was planning on upgrading my parent’s router to one of the better gl.inet models to replace their router and the Pi4. Configuration with goodcloud would be so much more convenient. I’m not going to do that if WG won’t work though.
The only other thing different going on on my network right now is my gigabit cable modem I use for my 500mbps service stopped connecting with my router’s (TP-Link Archer C7 v2, OpenWRT 19.07) switch at 1000mbps. The link speed is only 100mbps, even with a different cable. Everything works fine, I’m just not getting the max speeds I could get.
That issue probably pre-dates getting the MT1300 though. I just noticed it when I ran some speed tests to check the WAN/LAN throughput of the MT1300.
