Speed/Profile mismatch

[#1]

Hello there. We've had good speeds (over 5Mbps) for most of a year now, and everything has been more stable again since additional cabling improved the electricity supply in this area. In fact I think we just had a record: 28 full days without losing our internet connection. Hurrah!

But a week ago we had a power cut, probably effecting hundreds of routers connected to our exchange, and we reconnected with a line speed of 288Kbps.

Since Tuesday (7th) the situation has been as these BT test "further diagnostics":

   Download speed achieved during the test was - 1.2 Mbps
   For your connection, the acceptable range of speeds is 0.6 Mbps-7.15 Mbps.
   Additional Information:
   Your DSL Connection Rate :6.66 Mbps(DOWN-STREAM), 0.45 Mbps(UP-STREAM)
   IP Profile for your line is - 5.5 Mbps

Is there a reason why download speed is not anywhere near the IP profile? And how long might this situation last?

Give me 5 minutes, then disconnect/reconnect your router once.

In fact, the profile is set right on our side.  All you need to do is a disconnect/reconnect.

Despite a hiccup in the last minutes ...

Downloading now at 5.25Mbps. That should be fine. Thanks.
