We use wifi to access various streaming services via Unotelly. The wifi router is an NP805N supplied by Vodafone.

I find that to change location with Unotelly's dynamo service, I have to reboot the router (or else wait for hours). I guess that rebooting releases a buffer within the router.

Does anyone know what I could do to stop the router from behaving this way?

Unotelly provides help on disabling DNS buffering for several routers, but not this one. I've had a look at the various router settings, but I cannot see what I should change in the router settings. General googling of the problem has not been successful, so I'm stuck for now.
