I made the mistake of buying a Netgear DGN2000 ADSL2+ modem when I first got ADSL. Not only does it not support IPv6, its WiFi range is pathetic, bridging between WiFi and ethernet seems to die after several days of operation, and under heavy load the device hard-crashes, requiring a reboot. I suspect the crashing might be due to poor thermal design and perhaps my specific device but clearly the software is not also without some blame. Given my experiences, I would NEVER recommend this device. But, now that I have one that I can't return, I'm going to document the process of installing OpenWRT to see if I can give this thing a second lease on life.
