Hello Guy, I'm from Mozambique - Maputo province (Africa)!!!
I believe that our telephone network is blocking the softether, so that's why the internet is very slow in our country (Mozambique). I'm still not sure but I believe they've found a way to block the softether. I said, I'm not sure because the internet sometimes connects with full speed but when the MODEM disconnects from the Pc, it goes very very Super Slow. And it takes like hours to connect with full speed. It happens because I always connect and disconnect my MoDem all the time in order to try to connect with full speed. I don't if you guys can help us.
Sorry about my poor English. We speak Portuguese in our country.
