Cg3000dv2 is dropping wifi
Anytime I want to use wifi I have to go reset my router. And say I use my iPad for 5 minutes and put it down my network is undetectable . I've seen so many threads about this issue. I contacted my in...
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.
I just tried that... 2 minutes after factory re-setting the modem and restarting, I was logging in and... the WiFi went down again, and needed to be unplugged.

I just want to thank RSS3 for being a Great Samaritan; I've also had this router problem, and your fix... fixed it. There are a few other threads about this same situation on the Netgear forum, and they don't seem to be aware of the fix.
Anyway, thanks for posting your fix in this forum. I truly didn't want to have to pay the outrageous fee just to talk to a Netgear representative about what they screwed up in the first place. Netgear should have posted this fix from the start.
I tried the reset, keeping my fingers crossed. If this is the solution, Spectrum/TWC should be letting customers know as they push the firmware update. It's a shame their technical support is so clueless.
So far so good.. Reset last night. Obviously The firmware update requires a hard reset. Well at $50.00 a pop or more if you want extended service that should help netgear out.
Thanks to all
Can a hard reset be made, and then restore the settings from the bcakup file? I'd hate to have to re-set my IP rules and MAC addresses by hand for the 3rd time... (I've tried a hard-reset twice already)
MD585 - Sorry your having so much trouble. Sorry, but I am not the one that can answer your questions. The fact that you have had to do the factory reset more than once is a concern. I did loose wifi this past Saturday, turned off then on the wifi from the button on the front of the modem. Other than that I have not had any issues since doing the reset. As far as restoring or reentering your IP and MAC addresses is not something I had to do, nor ever entered my mind. The tech support never mentioned anything about that. Like I said prior, I am a former main frame design and test engineer. Been out of that for gosh 23 years now. Modems and routers I really never got into and don't know a lot about them. If you are past the 90 days for free support you could (1) call netgear support and tell them the issues your having same as posted and hope they will kind and not charge you since they started this mess or (2) contact your ISP, explain the issue and seek help from them. They should be aware of this problem by now or maybe need to be updated. I was 4 days within the 90 day period when I contacted them via online support.
