I tried the "Further Diagnostics" and though it seemed to stall I eventually got a page very much like the BT speedtester I opening with the question about
Got these figures
1. Best Effort Test: -provides background information.
Download Speed
3.11 Mbps
0 Mbps 4 Mbps
Max Achievable Speed
Download speedachieved during the test was - 3.11 Mbps
For your connection, the acceptable range of speeds is 1.2 Mbps-4 Mbps.
IP Profile for your line is - 3.38 Mbps
2. Upstream Test: -provides background information.
Upload Speed
0.73 Mbps
0 Mbps 0.83 Mbps
Max Achievable Speed
Upload speed achieved during the test was - 0.73Mbps
Additional Information:
Upstream Rate IP profile on your line is - 0.83 Mbps
So just need to check that PlusNet have the IP profile AOK

Edit ~ says 3.3 so PlusNet round down...............though I think I always knew that :lol:
