I use GSM connection to surf Internet. Before I moved to Ubuntu I used windows 7 OS. It gave me good speed with GSM connection (100 KB/s). But now Ubuntu gives me a very slow speed (2-3 KB/s). So it is difficult to use GSM connection. In my country (Sri Lanka) mobile broadband services are very expensive so I cant move to another one. If I use GSM connection they give me free data (AirTel connection). For me that is the main reason to use GSM connection. Please, can anybody help me speed up my Internet?
