Part of the Furniture
You are most welcome also have you tried changing the cable bettween the modem and the router?I am not running QoS or any protection as far as I am aware. Modem replacement would theoretically be possible, as it is a standalone unit, but I doubt it would happen. ISP would most likely just tell me to put modem out of bridge and connect to it directly.
Anyway I disabled all DNS protection/privacy settings, I will have to wait and see if the router drops connection again.
Thanks for all your help.
