I downgraded from the current to the previous and my DNLA was slow and choppy on many movies that use to play perfectly. So i reflashed after a week and now my file transfers Fail or are tranfering in the dial up range… things were all good until this new FW… im really fustrated. I hope the powers that be are working on a fix for this.
After you did the firmware changes, did you tried resetting the unit? If yes, try performing a system only restore.
See page 84 of the user manual to learn how to perform a System only restore.
