Cg3000dv2 is dropping wifi

Sorry to hear MD585 did not seem to help you. Your event log dump looks a lot like mine. I am not to savy with modems and routers and all the lingo so I cannot analyze it, I had the same critical 3, warnings 5 and error 4's. My background is large main frame design and test and thats been a while. May make me knowledgable enough to be dangerousas as they say.

Anyway, I am now post 72 hrs without any additional wifi drops. So I believe I am good. My sister reports that she is still good after 2 days.

Not saying you did not, not saying your problem is the same as mine, just ensure you follow the procedure, and I do not know if it all matters one way or the other, I just did exactly what netgear support instructed me to do:

Remove the ISP cable, then the power cord, reinstall the cable, then the power cord and I pressed and held the reset button for 40+ seconds. (He said 30 seconds)

During trouble shooting, we had changed several values (frag length, changed the channel number to 9 vs being auto). After the reset all were returned to the original values thus I assumed it had worked. Like I said, no more drops in 3 days. I did call time warner cable to alert them.
