N450 WiFi keeps disconnecting

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.

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??

Re: N450 WiFi keeps disconnecting

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! Smiley Very Happy

Re: N450 WiFi keeps disconnecting

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??

Re: N450 WiFi keeps disconnecting

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,

Re: N450 WiFi keeps disconnecting

I have this issue but only with one single item: my wife's Dell tablet.  The issue is specific to her tablet and this router and I can tether to my cell and everything works great.  I have alos taken to other WiFi connections and it works perfectly fine.  No other item in the house seems to have this issue either.  Any suggestions?

Have you tried to tell the tablet to forget the network and reconnect could be some bad saved settings in the tablet for that network. You may also want to do Ip address reservation for the tablets mac and ip address as the issue could be a IP conflict. You will find this setting in the router under LAN ip then  fill in the mac and ip address then click add under DHCP Reservation Lease.

Re: N450 WiFi keeps disconnecting

I bought my N450 at the end of November, 2015 and now (after the 90 day period, of course) it has started having wifi disconnects.  The hard-wired connection is solid as a rock, but the wifi just occasionally quits to all devices (Android and Mac), near and far, until I reboot the modem/router.  This is happening about every third day.  My firmware is the current one for Comcast (3.01.06).

Re: N450 WiFi keeps disconnecting

Additional info on the above post:  I had selected "Auto" for the channel in this single band modem/router.  It connects on Channel 1.  I installed a wifi analyzer on my android phone and found that, indeed, channel 1 has the best availability. Can I get a replacement for this device?

Hello craigwf

 

Have you tried to do a factory reset and see if the wifi is still dropping out?

Re: N450 WiFi keeps disconnecting

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.

Re: N450 WiFi keeps disconnecting

In case anybody is following this thread because they are having the same issue, I have now gone through Level 2 Support who made changes in the settings to no avail and has subsequently authorized an RMA number to obtain a replacement because they "have identified the hardware issue causing this problem."

Re: N450 WiFi keeps disconnecting

I've been getting the same issue since this update was pushed.

 

CG3000Dv2 N450

H/W rev: R2.05A2

F/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.

Re: N450 WiFi keeps disconnecting

It cost me $16.90 to get a replacement gateway shipped along with pre-paid return postage.  Netgear sent me a brand new (not a refurb) gateway of the same model as the defective one.  Thus far (3 days) the wifi has been rock steady 24/7.  I suspect a certain percentage of that model had a defective part.  Hopefully the replacement is not one of them.

Re: N450 WiFi keeps disconnecting

And on the 8th day, the brand new CG3000DV2 disconnected all wifi devices and would not allow them to reconnect until I unplugged and then re-plugged the power to the gateway.  What is causing this behavior?  Could this be the firmware Comcast has pushed to me, V3.01.06?  I am very disappointed.  I thought Netgear was known for reliability.

Re: N450 WiFi keeps disconnecting

After another three days from the last post, again got disconnected from all wifi devices and was unable to reconnect until a hard reboot.  Called Netgear Tech Support who was quick to blame Comcast saying that if the problem came from both the original purchase and from the "tested" replacement they sent (probably a return that had the same problem but seemed OK when they tested it for 2 minutes), then it must be a problem with the ISP.  They are, however, shipping me a new replacement unit.  We'll see how that works out.

Re: N450 WiFi keeps disconnecting

I called Comcast and some lady in India told me she would "synchronize" my gateway and that "this this will fix the problem."  After she did it, nothing changed on the gateway; it didn't reboot or have any changed settings.  Four days later I awoke to find all wifi devices disconnected and unable to reconnect until I did a hard reboot of the gateway.   Smiley Sad

Re: N450 WiFi keeps disconnecting

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.

Re: N450 WiFi keeps disconnecting

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.

Re: N450 WiFi keeps disconnecting

When I activated my third N450 gateway (Netgear graciously supplied me the third at no charge whatsoever), I explained the disconnect problem to the Comcast agent and she said she would configure my account to receive a "strong signal."  It has been 18 days now without a wifi disconnect.  Maybe the third time's the charm?

Re: N450 WiFi keeps disconnecting

Your isp controls your firmware.  You don't get to choose which version.  If you manage to find and install an older version of the firmware, your isp will upgrade you automatically to the version they are currently using for your modem/router.
