This is a post, that I've just not got time to explain in full yet...
But if you are stuck on 1-2mbps ADSL and have a bit of time on your hands then its possible to get +20mbps broadband.
I achieved this by load balancing a fixed wireless connection of 8mbps with a HSPDA 12+mbps connection. The HSPDA connection took most of the work and involved installing a fixed external yagi antenna for starters..
So far so good! PM me for more details.
