If the Internet is not connecting to a laptop and then no wi fi connection

What lights show on the router?

If it is a neighbourhood issue, you could consult Check service in your area  to see if any faults are being attended to in your local area.

Have you reported your problem with your BB to EE? They can't do anything about it until you do. Text HELP to 66033 to get EE to test the line & see what needs doing.

What is the name of the EE BB plan are you on including its speed? Which EE router & WiFi extenders, if any, do you have (read label or post a pix)?

Thanks. I went to EE shop. And not helpful. Green standard light on box.
No extension or other box provided or used. It's not an old laptop and
worked fine when BT were the provider

@Vickyg1-1 Green is not good, and @XRaySpeX asked what model of EE Router you have!

If green is the standard colour of the router's lights then the router must also be old. So let's have it.

No point going to a shop to fix BB faults!
