Hello, So I bought my Netgear N450 WiFi cable modem router on April 30, 2015 and in the past month I've been having WiFi connection problems. The internet works just fine, but for some reason the WiFi keeps disconnecting to any devices relying on it such as cell phones, ipads, roku etc. There will be times when I'll search for the WiFi network, and ours won't even show up. I've pretty much had to reset the router everyday and it just seems to be getting worse. I've tried contacting Netgear but because my item is over 90 days, they pretty much said google it and hope you find the answer. I've tried contacting squaretrade, where I got my warrenty, and they just took me back to Netgear. If anyone has had this problem, what did you do to fix it? It would be greatly appreciated.

Have not done a factory reset as the significant number of users with the same problem with CG3000DV2 who have done that say it didn't change anything. Interestingly, yesterday when the wifi was "down", I checked with my android wifi analyzer app and found the wifi signal was still up and strong, however no one could connect to it until I rebooted the router. It appears there is nothing wrong with the hardware generating the wifi signal, but rather a software issue as the router will occasionally disconnect all wifi devices and not allow them to reconnect until it has been rebooted.

I've been getting the same issue since this update was pushed. CG3000Dv2 N450H/W rev: R2.05A2F/W rev: V3.01.06 However my frequency has been 3-5 times per day all connections are dropped until I force a reset of the wi-fi by making configuration change(I usually just change channels or max speed, apply, and then revert). Router web GUI shows the wi-fi as up the entire time. With 3 family members using iPhones on a shared data plan this has put them over their monthly data limit in two days. I need a fix fast. I've been using all these same devices for nearly a year prior to the Comcast push that upgraded the f/w to v3 from v1.

I am having this same issue. It started within the last 2 weeks. I'm suspecting it is due to a TWC firmware upgrade to the router as the interface looks different than the last time I had to manage the router. It's currently running the same version as other users are indicating. I initially reset the wireless and rebooted the router and the devices would reconnect. Eventually within a day or two they disconnect and we have to repeat the process. This morning I tried changing the channel selection from auto (had selected channel 1) to selecting a channel 7. This did not work and in fact increased the rate of disconnect. I contacted TWC internet support. They started a remote support session with me. They started broadcasting the SSID and changed the channel to 11. When I asked why they chose this channel they said for 2.4 band routers they should utilize channels 1, 6 or 11. I will monitor and follow-up if this works (I'm a bit skeptical) :)

I can confirm that simply performing a factory did not fix the issue. Disabling the wifi afterward did (of course, as it was the problematic part), but that defeats the point of purchasing a wireless / modem combo.

Joined to say I'm suffering from the same issue, and I'm convinced it's the firmware. I bought the N450 in mid June and it worked great for ~3 months. 90 days. After that point, the N450 drops my connection. Wifi stays up and all my devices stay connected, but they won't get online. Contacted TWC/Spectrum — they've reset the signal dozens of times, and I've had techs visit 3 times and confirm my signal is perfect. Factory reset works for an hour, then it falls back into quitting every 30mins to an hour. Fix the problem, Netgear.

I just hooked mine up, and Comcast shows it's working fine. But it keeps kicking us off wireless. Anyone have a fix for this??

  Have you guys tried changing the wireless channel something could be causing interference with the signal such as neighbors routers, home appliances, or cordless phones.

    I tried EVERYTHING. I finally got the NetGear tech to throw up his hands and say the unit might be malfunctioning. Took it back to the store this morning, got a different NetGear model, and hooked it up with no problems! :smileyvery-happy:

I too am having the same problem: my laptop (Windows 8.1), and my daughter's Macbook and Apple TV experience loss of access to our home network at various times of day. I am forced to turn Wireless off/on, forget the network, and/or run troubleshooting diagnostics.
NETGEAR support had me change Channel from 1 to 11, and things seemed to work for a while, but now the disconnects are back. I have gone to the admin site and checked the power levels and signal-to-noise ratio for upstream/downstream power and they appear to be well within spec.

Anybody have any new ideas??

    Hi amitshah28,
    
    1. Does the issue happen on all of your devices?
    
    2. Have you tried changing the wireless channel?
    
    3. Does the issue happen whether the devices are close or far from the N450?
    
    Regards,

Same issue here as well. Talked to the customer service rep; he wants me to pay $89 or so for the additional tech support to try out settings, etc. I believe this is a bug introduced in the latest version of the firmware and has to be fixed with an update to the firmware.

    I don't believe they have come up with an upgraded firmware to fix it. Meanwhile, they may downgrade the firmware to solve the issue provided we pay whatever they are asking to pay. Nice way to make more money. For now, I am just re-booting the router every now and then to keep connected.

I faced this problem several months ago and I used a different router with this modem. Now I'm trying to debug this and I find the same issues described here.
- The wifi connection dies on almost all devices
- The wired connection is fine
- On changing the wifi channel (after connecting using wire), the wifi works for some time and usually within a few hours, it is down again.

Does netgear have a solution or a firmware upgrade planned? Will comcast deploy it?

I'm using the latest firmware version: 3.01.06

I've been using this for 2 years now (although I've had this problem for several months). I'm pretty disappointed that this hasn't been solved even though many people are reporting this issue.

  What is the second router you use to test with?
  
  I'm also having the same issue with my N450 with Time Warner. Only started noticing the issue recently. On TWC's site (Should I Lease or Buy a Modem page -> Download speeds up to 100Mbps section), the N450 is grayed out and listed as an "Internet Modem Only". TWC is probably trying to force us to an upgrade and make it seem like there is an issue with our hardware. Obviously this is not just an "Internet Modem Only".

    Hi:
    
    I used a Linksys WRT54G router which is an old router.
    
    I should add that this one was working well for a year and I suspect that a firmware upgrade ruined it. This is not just a modem.

Hi Darren,
Thanks for replying.
I checked the link in your post, it suggests that the firmware version for my N450 should be v1.00.05 but the actual version is v3.01.06

Do you mean Netgear gave a wrong baseline firmware to TWC or TWC pushed out a wrong version of firmware?

Hello,

This issue is happening to me too, have N450 and I'm a TWC customer
This is affecting all conectivity in the modem (wired and wifi).
This happend after someone (TWC or Netgear) pushed firmware 3.01.06
and it started about 10 days ago

Try to reset the modem and initiate a constant ping 'ping XXX.XXX.XXX.XXX -t'

After reset you should see regular latency numbers, as time goes by you will notice
that every 16 packet, the latency is much higher, if you leave the modem without restarting
for more then a day you might see 3000+ ms latency for something that is usually 30+ ms

Here is a constant ping to one of the servers (about 8 hours after restarting the modem) :

EXACTLY every 16 packets there is a much bigger latency.

Smells like a software issue.

I started seeing messages about this at the end of last month, probably someone initiated
this push, but I see that this issue has been going on for months from the posts here.

TWC says they don't push firmware updates to customer modems, and Netgear says
only TWC can push the firmware

TWC and NETGEAR - stop blaiming each other, take responsibility and fix this issue !!!

Folks, I suggest that if you want this resolved, start making noise in both companies.

    I came here looking for help because I have had the same issue. We have had the N450 just over a year and it worked fine until about a month ago. Then the wireless started becoming a problem. Computers were connected but had no internet and the only solution was to restart the N450. This happeded every few days. The past 3 days, the speed has been horrible. The disconects are getting worse. I see that this is a issue for many others and the blame is being tossed around. I chose Netgear because I have been satisfied with Netgear products in the past, but it looks like it's time to abandon Netagear and look elsewhere. One of my roomates works from home and this just will not do. We need a solution.

craigwf - from what I read you're on Comcast,is that correct ?

Also, from other responses about this issue, I understnd that the ISP's have ccess to the firmware source code,
I thought that maybe TWC has some bug, but if this is happening also with Comcast,
then I suspect the bug is in the Netgear code.

I just can't beleive that Netgear has avoided this issue for months, and now that TWC has pushed the faulty vrsion
(althoguh they will not admit it), they also, have to be responsible for fixing this.

THIS IS A NETGEAR FORUM, WHEE IS THE NETGEAR REPRESANTATIVE ????

  I neglected to mention I am also a TWC subscriber. I am thinking that perhaps I should pick up a seperate modem and router, that way any firmware upgrades do not impat the wireless protion. I am also thinking of puchasing one that I know they use. Before I moved I rented a Surfboard modem router combo that worked great except for the occasional hiccup. It would occasional drop signal but right itself after a minute. The Netgear has to be unplugged.

    I have the exact same problem! Just made an account so I can reply here.. Ping jumps on all my devices also internet gets slower the longer my router is turned on. Turning it on and off solves all these problems until 1-2 hours later i start noticing it getting slower again. After 1 day I usually cant even use it anymore(250mbps download speed goes down to 1mbps...).
    
    Guess I have to get a new router.

Has any of the folks here contacted TWC or Netgear and managed to make some progress ?

Also, I see that it is not recommended to buy a device that is both modem and router as the N450,
any one has any advice which modems and routers might be decent replacments (of course not Netgear) ?

  Nov 04, 2016
  Yeah, I think I've learned my lesson on this one. Between TWC / Spectrum and Netgear, I don't expect this to be resolved in any reasonable time -- even if Netgear has a fix, they'll have to convince TWC to implement and push it.
  
  Why the wireless firmware wasn't decoupled from the cable modem in this package is beyond me.
  
  I'll see if I can just disable the wireless on this and buy a separate access point for the wireless. At least the switch and cable modem in this aren't broken (yet).

Invalidation - are you saying that if we disable the wifi, the latency issue will not happen ?

Also, has anyone got a phone number to the netgear tech support ?

  Nov 04, 2016
  No, I'm saying, at least on mine, the latency issue is only affecting wifi. Wired is continuing to operate at full speed, even after wifi has fully failed.
  
  I *just* read someone saying otherwise in another thread, so I don't know if this is normal or not.
