Are there any techies out there who could offer any advice?

I recently moved to a new address (not far - same postcode as before). My router was absolutely fine in my old place, but now in my new one it's developed an ear-piercing whine. No new additions to my set-up - all same as my old address. I asked the engineer who came to set up my Broadband connection to check I'd set everything up ok before I even dared switch it on - he said it was all fine & good to go. Everything worked fine for a few days, but now it's whining at me. I've been onto my Broadband provider - they said I needed a new router. it arrived today - I've plugged it in & guess what? Still got the whine.....

All offers of advice will be very much appreciated - I just want rid of the whine!😢

goggle shows a few mentions, so seems not as rare as people may think

I'm with TalkTalk - they said I needed a new router - sent me one but still got the whine......

Update - Still got the whine - I've been taking to a techie mate & he reckons it sounds like a problem with the line rather than the router, so I need to get onto TalkTalk again....

And yet another update - I've just been on to TalkTalk & they're sending me new cables that should hopefully solve the problem & I'll be whine free!🤞

And yet another update on my whine problem......new cables didn't help either - I've been advised to buy some ferrite beads. No idea what they are! I've read up so much about them today but it may as well all be in Russian lol. Says if I buy the wrong sort it could make the problem worse.....I've just found some on ebay- bought some but no idea if they will work or not. Me & techno stuff are definitely not a good mix but I've got to get rid of this whine......!🤣
