The attenuation says you should getting between 8Mbps and 11Mbps now, so at 5770kbps something is very wrong.
You are also on ADSL2, where normally we would expect ADSL2+. Again, something strange.
On ADSL2+ on Sky you should get a bit more, but your maximum possible is 12Mbps.
There is a slight chance the problem is with the Orange equipment at the exchange, but it is more likely it is at your end. If it is at your end then you will probably not see any improvement until we find the reason you aren't getting at least 8Mbps now.
What have you got connected to your phone line as well as the broadband, and does everything go through a filter or does something connect direct to a phone socket? Particularly Sky boxes and phone-connected burglar alarms.
If there are extensions, were they installed by the builders or don't you know?
Has it ever been better than 6Mbps?
