hi, I recently purchased highspeed wireless internet from Kos. I live pretty much in the middle of nowhere but it recentl became available out here. We are paying for 4mb/s, but according to the tech guy that came to our house we are getting 1.5 mb/s... the problem is that im only getting download speeds of about 20 kb/s, 100kb/s on a good day. Also, the tech guy installed a tower on our house to make the signal stronger, but why would he tell us we were geting 1.5 mb/s if its not getting even close to that? is there something i can do to get to that speed?
