Just upgraded from ADSL to fibre, very strange speed problem.

[#1]

Hello, my fibre was activated this morning, after factory resetting and setting up my Asus DSL-N66U modem/router with the new settings I have noticed a massive speed difference between the what the modem, BT Wholesale speed test, speedtest.net and real world download speeds report, steam downloads around 600KB/s, everything tested using a gigabit ethernet connection.
The following imgur album has screenshots from all of the tests and my router DSL log: http://imgur.com/a/Qamvb

There will be experts around to advise but there is (for reasons unknown) a plusnet profile which is prob set to your ADSL speed (check here https://portal.plus.net/my.html?action=data_transfer_speed). Live chat can reset or it may follow your sync rate overnight. That looks like a 40/2 service.

Hi there,
I've just updated your profile so you should see a difference straight away.
