Any streaming media (youtube, flash etc) or otger downloads would randomly (so I thought) stop and not resume. Turns out that this will happen when my router renews while in DMZ plus mode, which is every 10 minutes.
Hitting renew manually can replicate this. This did not happen a few months ago. I cannot say when it happened but it definitely started after getting the replacement power supply for the 2wire.
My router is a WRT54G running Tomato 1.27. Been flawless like this since day one of getting the 2wire some 2 years ago.
If this started after you got the new power supply I would suggest you get that modem replaced.
