HIGH SPEED IS LOW SPEED INTERNET IN KOH PHANGAN THAILAND

I am having tons of small problems with using the Internet in Koh Pha Ngan, Had Rin Beach Thailand. My Laptop or Notebook cannot be connected or at least I have not found a place. The high speed connection is slow. The pages flip and do not send or initiate correctly.

I NEED TO COPY OF COPY AND PASTE TO NOT LOSE MESSAGE!
I always highlight and copy before I will click on send.
