I have Comcast and randomly during the day my connection would just die, originally I believed it to be IPv6 causing the trouble ( see here http://pastebin.com/psbJTYrT ), the only way to fix was to either unplug the Modem <-> Router Ethernet cable, or restart the modem (Like when I disabled IPv6 in the router and the web ui just froze with the "Completed" box still up and the icon still spinning so I had no choice). But if you look at the log (which is from today btw) it's as if the router is just randomly rebooting on its own intermittently so I'm not sure what to think, if anyone else has any ideas please feel free to help me, I am completely at a loss, thank you!
