Definitely worth opening a ticket with Vivaciti. I'm on the partial LLU service and only been on it a month or so and it maxes out just about anytime of the day. I have a Billion 7800 wired which has a throughput problem on current 1.06e firmware. I swapped my router over to the old speedtouch and the throughput problem is solved so dont discount the router.
Having said that my speed was affected by TCP re-transmissions in the router aka pauses in big downloads say 100-200mb in size. Speedtests are unaffected as the download filesize is so small it doesn't seem to stress the router.
I'm beginning to wonder if it isnt a compatibility problem between the Billion and Broadcom Line card/DSLAM. I got set-up details from Surfwise but when I run speedtests it says O-bit telecom so maybe they are changing name. Certainly worth contacting Viva.
