Reconfigure DNS settings for a Trooli Technicolor DGA4135

How do I reconfigure the DNS settings for a Trooli Technicolor DGA4135?

I would refer you to this thread: https://forums.thinkbroadband.com/multiuser/4771309-... which has no useful help.

Looking at A&A's wiki, it seems that for A&A, this router downloads its WAN side config from the ISP and you ahve to go to the ISP's web config pages to alter any of these setttings. DNS is WAN side, so you might be out of luck. One of the perils of ISP provided routers. Other than that, you need to scrape around on Google.

Trooli allow you to use your own router and will tell you the logon credentials apparently. That is the route I would go down, keeping the Trooli router to hand if your line goes down, so that they don't get confused.

On my giganet unit its "internet access/show advanced/Manual DNS Configuration"
