I tried many other ports including port 80 (which by the way is used by Google Earth Pro to connect) but no use?? Google Earth Pro works perfectly on port 80!!
Still to try the new version!!
U guessed it right Grandpa tht my internet connection is a PPPoE service! And I found some kind of machine on the top of my building which distributed cable wires to subscribed customers!! Couldn't see wht it was since it was closed in a locked box!!

Keep sending inputs!! Thank U!
