How to run BT Test 3 on FTTC with Airport Extreme Router?

[#1]

Managed to do it by changing the router settings, connecting and then going to http://217.35.209.142

If you have a similar situation in the future (i.e. you have a problem then solve it yourself), can you still leave the original problem's text intact please, so that the thread makes more sense to those with a similar problem who might search the forums in the future. Thanks.

Sorry 'bout that - OK for their benefit:
The problem was that if i tried to follow the BT speedtest procedure, after completing test 1 & 2 and being asked to change the login credentials before running test 3,  I was able to get a PPOE connection, but the test 3 just stuck at checking user details. Using the procedure above helped me solve it.
