I have now tried both routers and am still having device connection issues. I was sent a new router as I was told the old one may have a fault, which has now been diagnosed as an outside cable issue, but if I connect the old one everything works a lot better than with the new ones.
The old one is Hauwei HG633
There is still an issue which openreach are supposed to be sorting out but I don't know when, as I have not heard anything from either talktalk or openreach regarding when they are coming back to fix it. Internet now been playing up for nearly a month, not happy seriously thinking about ditching talktalk if they don't do something soon.
