New router installed still dropping out
Help I am not at all technical so floundering!! I have super fibre broadband via open reach cabinet. I recently had issues with internet dropping out and was recommended to install new router. I received and installed Plusnet hub one, connected to telephone line via open reach modem. I gave this 2 weeks to settle. It is not as bad but frequently drops when using FaceTime/Skype and now Sky will not work properly, saying no internet connection but when I check on settings shows all connected.
Help any advice on the best way forward would be greatly appreciated
