Gets Disconnected

Friday September 21, So so
I wrote a diary in the note pad yesterday.
Because the internet was very problem.
Today also I got disconnected from the internet
that I felt so so mad.
I use broadband which often gets disconnected.
The internet sever used to be good.
Just now it was suddenly slowing slowing down
and had other problems.
Such a problem with broadband ?
Should I check it out to the internet company?
