Internet Connection Dropped - Netgear Router Settings

One possibility that comes to mind is maybe there is an issue with the Ethernet connection between the modem and the router.  It might be worth trying a different Ethernet cord if you haven't yet. 

I recently replaced a Linksys wired router with a Netgear N900 wireless router (WNDR4500V2) and I am now having the same problem.  The internet connection is dropped once per day, nearly every day, generally during the middle of the day, and usually when none of the connected systems are active.  I have tried every suggestion I could find on this topic from the Netgear online forum -- except back-leveling the firmware -- without success. 

The Linksys wired router did not have this problem.  Other than the almost daily internet connection drop, the Netgear wireless router seems to be working fine.  The drop problem has become pretty maddening, though.  

Any suggestions would be much appreciated.  Thanks!

I have the same exact problem, same router. Net gear even sent me a new router, same dropped daily connection. Cox tech came out a week ago, replaced some connections and a cable. Worked for a while, but dropped last night. Starting to think reliability is more important to me than extra speed. Is Cox listening? Very Frustrating

I have tried a different cable from the modem to the router, Cox has swapped the modem out, I have adjusted the MTO size, unchecked a box in the WAN setup, all suggestion found on the internet, still dropping the connection. 

I may have to purchase a new router of a different brand.

It is becoming very frustrating. 

The next time you see it occur before you reset anything if you log into the router and verify if the public/Wan Ip address is valid or if it resets to 0's or is blank that will verify if its only dropping there or if it is on the modems end locking up on routing or issuing DHCP information there.

First have you checked to see if all of your routers have the latest firmware?

                                     And

Have you checked the log files in your router?

What do I look for in the router log?

I haven't lost connection in sometime and now I have had to reboot the router 3 times in the last 24 hours.

I think it is a Cox issue to be honest.

I think the problem might be how the Netgear gateway negotiate the Wifi channel with the client when set to the "Auto" scan feature with 20/40 channel width. I also see a substantial latency spike each time the device changes channels. Logic would dictate this problem would cause more symptoms when in a environment with more network congestion of the Wifi-N band in 2.4Ghz. I also think that is why the problem is only effecting those that have the gateway set to default configuration. 

any suggestions for a solution in simple terms?

Hate to sound like a broken record, but easy solution, at least in effort, is get a new router. That also means buying a new modem. But then you can separate ISP from network issues and work on them separately. Right now the gateways provide a "plug and play" type service that emphasizes simplicity over quality. Like bluetooth.  You could probably troubleshoot you way around the problem with moderate effort, but there are better wireless products out there IMHO.

I have noticed that my connection drops every time my IP address from Cox changes. I have not found a solution yet.

If you're on a business account I would speak to our business technical support to see if you're supposed to be on a static IP address.

What data do you have about the IP? Reason I ask is I was troubleshooting a problem someone else was was having with a netgear gateway and we were thinking the same thing. I can't imagine its all the units. Im thinking maybe a local issue. May I ask which state your in and if you happen to know what firmware your using?

All,

I downgraded to an older version of the router's firmware and have not lost connection once.

And to be clear, this was a Netgear router you bought on your own, right? Not the Netgear gateway? Good, glad it worked out.
