I had a few issues with the GT-BE19000AI version with this beta. Around 36 to 48 hours after flashing this beta, I lost the wired connections to my Synology NAS and Raspberry Pi. They both showed connected on the GUI dashboard, but they both had to be rebooted to restore their internet connections. Roughly 24 hours later, the Adguard Home instance running on the AI Board quit working. AdGuard Home container showed running normally in Portainer, but I could not connect to the internet through Adguard Home. I rebooted the AI Board and it started working again. There have been several stock firmware revisions released over the last few months for this router, so it could just be an issue with this particular GPL. I have loaded stock firmware version 3.0.0.6.102_40425 to see if I have similar issues before my return window closes.
