I ruled out windows updates but probably wasnt investigated as much as possible, when i was doing some of the testing to check if it was a dodg modem etc i had a direct link from my phone line -> modem -> laptop with laptop picking up 0kbs dl/ul on DU meter(if unknown, program for recording dl/ul speed), so with no computers on teh net and laptop going at 0, doing a speed test my lag was still there, could have been investigated more as ive only done that 1 test, however i thought that was pretty hard proof it couldnt be them. ill give it another go turning them completely off and seeing how i go.
secondly,
not sure were this forum is located, so ill give some context, telstra is the australian company who run majority of the lines in aus, and then they rent them out to the other isps etc, ive had telstra come out and check my lines without any report of faults so i was assuming they checked out of the area, however my lines are fairly old as they can only support speeds of 1500, hence no adsl2 or even top end adsl.
i will give the barebone profile a try and see what happens. thanks a lot for the fast reply
