I should have added that when this happens, I can't even connect to my R2 to access the DumaOS backend. It just disappears from the list of available Wi-Fi networks on all my devices, despite the first two red lights being on on the R2 itself. When I connect over Ethernet, I cannot access the internet or the backend.
Weirdly, I can't even seem to perform a factory reset. I hold in the reset button for 30 seconds, and it just does... nothing. The lights don't turn off or change, nothing seems to happen.
