All, as the title suggests. Literally had a power cut a few hours ago and when the power was restored, the Flint 2 was not connecting to the internet on Ethernet 1. Tested this on Ethernet 2 as WAN and connected first go. Tested this on my old Time Machine which also connected first go.
Any other troubleshooting that can be done or is it a case of sending this back to Amazon? I've already ordered a replacement to minimise downtime.
