tunafish: Thanks for the info, yes my speed is 1.4Mb/s, which as you say it is slow for BB, but I am a few k's from the exchange, my router indicates a sync a 2Mb but Speedtest only goes to 1.4Mb/s.
What I am finding is session time outs if I go away from my PC, long delays before pages load, and when my son is gaming his session gets dropped, this is what I expect a cache proxy to do when they get overloaded.
2Mb sync is slow... How many K away from the exchange are you? Have you asked your ISP if your speed is consistent with the distance from exchange? Have you confirmed that you don't have an inhome wiring issues (like missing or broken filters, or a Sky box without a filter?)
What is your negotiated upstream speed?
