I'm currently with Freenetname on their 2Mb package.

I recently received an e-mail asking if I wanted to upgrade, FOC, to their 8Mb service.

I agreed.

Today I received an e-mail stating the upgrade was complete.

I reset my router (Netgear DG834), as instructed. When I reconnected I was informed by the router status display that my new downstream connection speed was 7616kps.

Great more speed!

However, whenever I use any of the "test your line speed" sites such as http://www.speedtest.bbmax.co.uk/

I'm told my speed is around 2Mb.

Any ideas?

Thanks in advance.

Ok, I'm fine with the waiting, but why is it my router shows the new, faster speed, when I am not actually getting it?

I'd understadn if it showed the slower speed for a few days, but not too sure why its showing faster speed currently.
 
The speed you're seeing is the line rate sync speed. In other words, the speed your modem is talking to the ADSL port in the exchange. However, the problem is that your connection is being throttled within the BT network at the BRAS as it is still built with a 2mb profile. PM me and I'll sort it.

Read some of the other threads!

BT limit the data rate with the BRAS profile as without a limit it would cause ATM line buffer overflows, which would then cause your line to break. Not good. The profile isn't increased until BT's system is satisfied the line is stable enough.

wouldnt cause any such thing. 8128 is max sync and that includes ATM overheads so data rate is around 7000.

No limits would cause the ATM line to become full, and then start to drop packets. ATM cells are 48bytes, so one dropped would cause a whole 1500byte IP packet to be sent again. Worst case, the same packet would lose 48 bytes everytime causing no traffic to get through - line broken.
