I too have had issues with the U-Verse NVG-510 ever since the beginning. Modem reboots several times a day for no apparent reason. And sometimes it locks up and I have to unplug the power to reset it. I have updated the firmware to 9.0.6h2d21, and that was not an easy firmware to find! ... But it only helped the DNS issues. It did nothing for the rebooting issues. Any help is appreciated
