The 333 board sucked. That simple. I have dozens of customers with RB411 CPEs and our power is pretty good - never had to reboot the CPE for the last 6 months (we started deploying them 6 months ago). The 133 did have that power problem and I saw it many times, however, a $50 UPS can fix that. Not to mention if someone has a PC they should have one already...
