My WD Duo seems to work just fine.
The output from the Pace 5268 feeds into a Net Gear 12 port switch, and one of the outputs from the switch feeds the WD Duo. Try feeding through a gigabit switch (5 port switches are as little as $20) on your home network and let us know if that works for you.
Tom on Brentwood Fiber and one happy camper!
Glad to hear that's working for you!
For everyone else, we do finally have a fix in production, and we are beginning to update customers to this new version.
