reporting slow streaming speeds

[#1]

been having jerky streaming speeds recently. Connected to router via ethernet Bt speed of 6.7Mbps, Only used 10% of monthly limit so hope I am not throttled. only talking about BBC iplayer viewing with no other connected items using broadband.
Looked at the Plusnet troubleshooter and got half way through and was asked to change over the router. I dont have another one. is there a way to raise a query over the speed/ an issue without being threatened with a charge from BT (or someone else) just because I do not have another router?

Have you tried the iPlayer speed tester? http://www.bbc.co.uk/iplayer/diagnostics

If you don't have a spare router to try, the best you can do is answer the question to say 'you haven't tried one', and press on. The final question provides an "additional information" text box and in there comment to the effect that "you haven't been able to test another router as you don't have a spare. Would it be possible to borrow one?".
That will get the question submitted to the faults team and initial line tests carried out. Depending on these results the faults team may feel that testing another router is essential and contact you to work out a way of doing this. They won't send an engineer (risking a charge) before this is done as long as you cooperate with them.

I've just been running some account and diagnostic checks and can't see any obvious issues that might be causing what you've mentioned. Re progressing the fault I'd do what spraxyt suggests if you can.
