New router for digital phone

[HB73]

Hi.  I was sent a new router in February  as the landline was now digital.  To date I have had 3 routers, two adaptors and three engineer visits. I have spent over 15 hours on landline - when it works - trying to fix problems. It is an intermittent fault but most of the time doesn’t work properly. The television either buffers or asks to check network connection. Sometimes takes 20 attempts to phone out on landline - messages saying line out of order or unrecognised number or not available. People ring me on landline or mobile but phones don’t ring but sometimes says missed call when I’m standing by phone! The PC and air printer won’t work, the iPad buffers and very slow and takes multiple attempts to pay bills and access online banking.  I have been advised to change phone batteries, passwords reset numerous times, unplug and plug in, reset to factory settings. My security cameras are offline and  communication via mobile and landline not possible most of the time.  Has anyone got any advice? Everything fine on the old router but apparently have to have this one for landline.  Many thanks.

@x91 That would be the correct way to go about it, think the OP has established FTTC connection and 1600M of copper cable from the Cab to the home, good few splice connection points between that distance, more than likely just jobs stacked up together and copper on it's way out shortly, one just never knows what is going on with it all currently... Had a few contractor's to OR promise the earth to me, never transpired and had EE on the speed dial every two weeks or so when the sync tanked...

Had the wife bending my ear with the W T F is going on with this Broadband get back to Sky and lose this EE connection! Bad cable joint box sorted it all out!
