Random Disconnects Every 15 mins or So

[#1]

Hey all,
I'm at my wits end, and in desperate need of some help. I recently purchased a new router (last Friday), and as far as I can tell my connection has been stable until today (worked from home so I was relying on 100% uptime). What is happening is that every 15 minutes or so my router is reporting that my ADSL status is FAILED (rather than the expected SHOWTIME). My new router is a Draytek 2860AC which is a big step up from my old Asus, and therefore I am wondering if maybe I have configured it incorrectly. In order to rule out that problem would someone with a greater knowledge than I confirm that my settings are correct for my 20CN ASDL connection:

Any further information you need please let me know. I've checked the service status page and I can't see any current problems on my exchange

Thanks for looking into it Chris, looks like the problem was external as I didn't change any settings since posting this thread. Crossing my fingers that BT stop snoozing and hurry up and upgrade my cabinet
