I have a 8mb connection at home but can only get 2Mb at work with a 256k upload speed. I called BT to get it upgraded but they said they can upgrade it to 4.5Mb but the upload will stay the same (256Kb), unless I upgrade further to 'network services' which is £100/month, yet my home connection, which I believe has an upload speed of 832Kb doesn't cost anywhere near that, but not on BT.
