As the name suggests, when I try to go to the expert_user page to check my address reservations I get a 404 from the router. Everything else works, basic and advanced settings all good.
It used to be available - I originally set some reservations which are still active. That was after I changed the router address to 192.168.0.1 - it's been that since day 1 - first thing I always do. I've tried http and https - always 404.
The only thing which has changed (today) is that I added the static IP option for a fiver, which has taken correctly after the reboot.
