Download has fewer frequencies available, though at your sort of speed it wouldn't normally cause the loss you have experienced. In fact it would often cause a downstream increase.
Do you know your attenuation figures? I suspect your line/wiring is under-performing and always has been. In which case we may be able to get you to better than on O2. (But not the upstream, unless you can get them to upgrade you to ADSL2 or ADSL2+).
