You should be syncing at about 17 Meg. The reason you are not is that EE has put you on a banded profile, the 4th lowest of these Banded Profiles, altho' you now have no significant errors. You need to call them to remove any banding.
For me that sounds like a good speed - the most I've ever got is 8.5mbps so I'll be over the moon with anything near that!
I've just got off an hour-long call to EE tech support (offshore). The first guy did about 3 'line tests' and then put me through to another team, the conversation with which went kind of like this (and apologies for the cynicism):
Me: explained the simple situation that my line had been faulty for a number of months, has now been fixed, and I'm still getting 2mbps so can they look at my settings.
Her: "ok hold the line" - 2 minutes pass - "You're having a problem with your line?"
Me: "No" - explained again
Her: "ok let me do a line test, please don't hang up" - 3 minute pause - "ok hold on" - another 3 minute pause - "ok don't hold up" - 3 minute pause - "ok we're just waiting for the results" - 5 minute pause - "ok the line test has come back clear, hold the line please" - 2 minute pause - "you reported you're having slow speeds, are you having drop-outs?"
Me: "I was having regular drop-outs before the line was fixed this afternoon, but now the line is clear and my b/b hasn't dropped out at all so far"
Her: "ok hold on" - 2 minute pause - "I'm just running a broadband check" - 1 minute pause - "don't make or receive any telephone calls" - 5 minute pause - "ok please don't hang up" - 3 minute pause...
...you get the idea...
I'm sure between the pair of them they did about 6 ""line tests"". Anyway at the end she told me to leave the router switched on for 24 hours and they'd call me back Sunday morning. Let's see...
