I'm using a 3G wireless dongle to connect to the internet. On Windows there's a software for this dongle but on Ubuntu I can use it without any software's. But the thing is that this connection can automatically toggle between GSM and HSDPA modes. When this happens my connection speed goes very low. On Windows I can manually set this to just work with HSDPA.
Now I need to know how to set this up on Ubuntu and make the connection just work with HSDPA.
