Experiencing issues with my broadband

[#1]

My internet will go on and off for a good two three minutes and will stop connecting to all iPhone even after I have renegrees the password? Does anyone know how to fix this?

First thing to check: Is your phoneline clear? Dial 17070 (preferably from a corded phone), select option 2. Once your phone number is confirmed, there should be silence on the line except for the regular 'Quiet Line Test' message - any other noise, report a PHONE problem via: https://www.plus.net/help/report-a-problem/phone/

If the phone test passes, report a broadband problem via: https://www.plus.net/help/report-a-problem/broadband/

Let us know the result - if the tests come back as clear but you still have a problem, we need to investigate further.
