Stuck IP profile?

[#1]

Just checked my router stats to find my router is synched at 12,052 (on 21CN), however the PN speed profile has been sitting at 5.2Mb for a few weeks now.
Does this mean it's stuck, or will it eventually increase my line speed?
Should I raise a support ticket?
I only noticed the problem with my speed when I was using BBC iPlayer HD which started to buffer which it has never done previously.

DSL Type: G.992.5 annex A
Maximum Bandwidth (Up/Down) [kbps/kbps]: 1,140 / 12,052
Bandwidth (Up/Down) [kbps/kbps]: 443 / 12,184
Data Transferred (Sent/Received) [MB/MB]: 4.58 / 46.30
Output Power (Up/Down) [dBm]: 12.0 / 20.0
Line Attenuation (Up/Down) [dB]: 8.0 / 21.0
SN Margin (Up/Down) [dB]: 28.0 / 12.0

Hi gavin11,
I have raised your profile to 10700 to allow for your new BT IP profile. This should take effect shortly.

Perfect, now getting speedtests in excess of 10Mb and iPlayer HD is working perfectly.. thanks Jojo !
