I am on max and get similar problems, connecting at 12-14meg

download speeds from newsgroups and test sites vary from 60k to the correct 1.5meg kbps download speeds.

depending on, well no idea, it can be fine downloading at full speed, router goes off and i get poor speed, reboot again and its fine.....

router can stay on for days at a time but then i just lose all internet access, a reboot and the speed changes again... strange
