Hi, Starlink UK business user here. Sorry for the long post but a resolution might help others and thanks in advance for any ideas.
The issue
Draytek router requiring restart to regain internet access, seemingly when Starlink goes offline momentarily.
Short term resolution
Restart draytek router which works 100% of the time.
Info
V2 Rectangular Dishy Business account with public IP activated.
100% clear view with no obstructions.
DL: Up to 300, UL: Up to 20 and very stable 9-5 during business working hours.
Firmware of all devices / hardware up to date.
Cables all tested and good.
Restarting of devices and factory resetting performed several times.
Draytek router WAN settings setup to obtain IP automatically.
Draytek WAN Connection Detection set to 'Ping Detect' Primary: 8.8.8.8, secondary: 8.8.4.4, TTL: 255, Ping interval: 1, Ping retry: 10
Draytek LAN DHCP disabled as Windows server running DHCP / DNS. Issue evident with Draytek running DHCP so server and other devices on LAN are not the cause.
I have two Starlink ethernet adapters and the original router in stock if needed.
The setup
Dishy connected to Starlink POE brick and POE brick connect WAN2 of Draytek Vigor 2865 router using Cat6.
Draytek router LAN port connected to TP Link smart switch.
Test laptop connected to Smart switch with remote access available.
The rest of the network is insignificant as issue still evident when cable link from switch and router disconnected and test laptop connected directly to router LAN port.
Attempts to fix
Configured PING detect on Draytek to attempt to get it to renew WAN IP and reconnect - FAILED
Plugged Starlink POE brick, Draytek router, switch and laptop into UPS in event that it's a power blip - FAILED
Ideas yet to try
Connect small network switch between Starlink POE brick and Draytek router. Read this on the web so Kudos if it works - PENDING

Setting Draytek on reboot schedule is possible but not practical.
