Getting intermittent bursts of performance on my ADSL2+ connection since Monday. Basically I get 5-30 seconds of good data volume, then 1 minute+ of zero and then it picks up again. This is very apparent when streaming from youtube and direct downloads. Torrents provide a very steady stream of data but they seem capped at around 100kB/s



I've tried resetting the router, checking the line filters, upgrading firefox. Just want to know if theres anything else I need to check before I call my ISP?
