The external cable from the telephone pole to my house is hanging off from the box that is fixed to my property.  I have tried to telephone but getting nowhere. It needs rectifying as it’s hanging in a dangerous place

My Router has started to intermittently lose power, pressing the power button at the back sometimes switches it back on, sometimes it loses power again after a few seconds   I need a new router if possible please   I cannot get any help over the phone or from the live chat as it's all automated and neither understands what the issue is   Any help appreciated Chris

I logged in to the WiFi Hub and changed the WiFi password in the WiFi settings. I then saved the change and exited the screen. I logged back in to ensure the change had taken effect. I was pleased to see it had. I then proceeded to browse but quickly realised I had no internet connection.  I tried troubleshooting but nothing worked. I remembered the Ethernet cable and that connected me. I  searched for the problem and discovered in Network & Internet, in View WiFi Security Key was still showing the old WiFi password. I have looked at the Advanced WiFi Network Properties and the Edit feature and wonder if I also have to edit the password here. I don't relish that as the screen size and text is tiny like many Windows 11 important pop-up screens. Can you remove a lost or mislaid device from the network that is not in use but may be in use in the future? What is the Guest connection and how does it work?   Please confirm the correct process for changing the WIFi password.        

My contract ends at the end of this month. I brought a router from talktalk about 5yrs ago as the original router was playing up. I paid about £25 for it. I'm not getting any clear answers from the live chat or the person I spoke to when I notified them about leaving about returning my equipment. I have told them I brought it from talktalk but all I'm getting if I don't return my equipment I will be charged around £50. I don't think I have the original router as it wasn't working properly, hence why I brought a new one. Can anyone help with this please?

Tried to open Chrome with Google as home page this morning, but got a "This site can't be reached"   Also cannot load Amazon, eBay, same with my local library page, MobileRead forum etc.    I cannot open anything with Chrome.   Tried Edge and everything works, can download Amazon, eBay etc. etc.   I also use Thunderbird as an email client, and that isn't loading any new emails either, and doesn't even let me know it can't download them.   I've run a full scan using my virus checker and it's found nothing under malware or system.
