Cannot connect to ISP (Plusnet) with latest firmware on Archer VR900
Hi, I tried upgrading my VR900 firmware to the latest version to try and improve reliability and it is not able to connect to Plusnet (my ISP). If I downgrade to the previous version it works fine. I've tried a factory reset on the new firmware and setup again but it always has the same issue. If I then apply the older firmware again it works without any changes. This is an export of the system log when it tries to connect:
