why is my internet so slow i'm constantly having to restart the internet!!
If you can provide your details i can do some analysis and advise you if the issue is wifi related or actual line related.
if its wifi related i can give you some tips and advise.
nowadays master filter is not required depending on the situation though. the normal filter is only to filter out the voice frequencies/tones leaving all other tones to be used.
But cant come to a conclusion without looking at your connection at this stage.
