Why did my broadband start being erratic ?

[MA1023]

My braodband has worked fine for over a yearm, but now it is very flaky.

I work from home, and I have several computers.

Some work with Sky braodband, and some stop working 

I have tried resetting things.

i have tried a broadband check, and it is says "all is good" whilst the computer in front of me says no access to the internet

Even my Sky Q box can no longer access my sky braodband box, and they are about 10 feet away
