Please don't tell me you go thru insight! Insight are reknown for either filtering or blocking p2p use particularly LW. But they always deny it! Either search insight on the forum or do a google search for 'does insight block p2p use'. If I'm wrong about your isp then my apologies. But at least ask them whether they do block p2p. Tell them you pay for a service & you believe they are either blocking or filtering (limiting your speeds) your service. Ask to speak to someone in authority & not just a puppetry character.
