Things have gone from bad to worse after this firmware update. Now my wireless network is not working. The router is broadcasting the SSIDs, but the clients can not connect to either radio. No matter how I try to reset the router the WiFi configuration of the radios remains. Is like the router is never factory reset. I tried holding the reset button in the back for ~30 Sec, I try using the GUI Revert to Factory Settings "Erase" button and I also tried using the NVRAM reset ... 30 sec while on... 30 seconds while off and 30 seconds while restarting.. but no dice. (90 sec total with the reset button pressed) Those wireless devices that somehow now manage to connect via WiFi are listed as wired under attached devices. The two devices underlined in red and listed as wired are Chromecasts dongles (MACs not listed, but I verified them). I also tried re-flashing this current new version and the previous 2.1.3.7 firmware version, but no matter what I try nothing seems to fix the wireless problem now.
Earlier today after the update I had to restart all my wireless devices for them to re-connect. This was never the case before. They always reconnected by themselves after the router restarted. Something is not Kosher here. This update has ruined my router and I wasted a whole day trying to fix it. What now?... Can the developers send me a newer/beta firmware that I can try? Any other suggestions?
UPDATE: Last night after resetting the CAX80 via the reset button in the back ~10 times using different time intervals while power cycling it, I finally got the wireless network to kick-start... BUT the WiFi settings: SSIDs and Passwords and the such remain the same since the first time I set it up. I have found no way to reset the WiFi settings with this firmware.
Also, I just noticed that the Web GUI is currently stuck in the hour glass. I can select options in the left panel, but just get the hour glass on the right.
UPDATE 2: NEVER MIND!... Once the GUI gets stuck the router stops responding and all wired and wireless connections are lost.
IS THERE ANY WAY TO MAKE SURE THAT THE ROUTER IS "FULLY" RESET TO IS FACTORY SETTING? Who knows, maybe I'm not doing it right.
10-15 second press on the reset button should be enough to clear out and get a full reset.
Be sure your also clear your browser cache as well before re-entering the modems web page at 192.168.1.1.
Do you get the setup wizard here after you reset? You should see the nighthawk app suggestion web page then the link at the bottom to select if you don't have a mobile device to setup the modem with. Use this to set up the modem with a wired PC and web browser.
"10-15 second press on the reset button should be enough to clear out and get a full reset"
I have tried short 10-15 sec and longer intervals. The result is the same. The router reboots, but the old WiFi settings remain.
"Be sure your also clear your browser cache as well before re-entering the modems web page at 192.168.1.1.
I have done this using and also used different routers Chrome, Firefox and Edge.

Since this update I always get the "Setup Wizard" regardless of the reason for the restart (This is what I've been calling the need for Re-Authentication via a Web Browser every time the router reboots. I have to enter the password, answer two questions, click next to the WiFi setting which remain unchanged (weather I reset the router or just reboot) and then get rid of the Pop up with the Armor something or other offer. Very annoying.
I have left the router alone after the last reboot. If I interface with it via the Web Browser GUI I run the risk of having the GUI hang with the hour glass and then a subsequent router freeze. Sometimes only the Wired devices are able to connect. I have made no attempts to change any setting, but I'm sure the devices names, icons and IP addresses reservations are gone. Some of the devices that I ping on predetermine IP addresses are currently using a randomly assigned IP addresses.
I will probably leave it alone for a while as I have to go to work and probably won't get a chance again to work on it until the weekend. I already started my search for separated component solution (Modem + Router) rather than an integrated solution like the CAX80 which has been a nightmare starting with the fact that it reboots when it losses ISP connection. I need to maintain a working LAN even if no Internet signal is available. I have a NAS, printer and local streaming devices which I need to access to even when no Internet is available. Currently leaning on getting a Motorola MB8611 Modem and an ASUS RT-AX86U Router if this issue is not resolved soon. I take any other recommendation for a Modem/Router combo for Spectrum that anyone cares to give.
Ok, sounds like something is faulty on this modem. Let me check on this.
OK... thanks. I'm about to message him. Hopefully, I will get a positive response. A cross RMA is exactly what I need, I don't have an spare modem or router.
There waiting on ya. 😉
I had exactly the same problem with my CAX80 but now it even worse. It's bricked by the latest firmware.
My router also reset all the configuration after power loss or even rebooting from the GUI. Then NG support engineer advised me to manually update my router to 2.1.4.2 and now I have it cycling in an infinite sequence of blinking LEDs.
I tried to upload the firmware via TFTP according to this article but the power LED never turns orange as it stated in the article.
Can somebody help me to figure out what to do?
It is unacceptable that Netgear publishes such a raw and glitchy firmware as "stable"!
Is the Coax cable still connected to the modem when this reboot is happening?
What browser did you use to push the FW file?
If a reset of the modem with out the coax connected, then reconnect it after a few minutes doesn't bring the modem back to recovered, re-contact NG support or whom ever contacted you and let them know what happened. Nothing else we can do here in the forums.
Hey everyone,
So as I see, I'm also one of many victims of Netgear's incompetency and ignoring.
I bought my router from a reseller on Amazon for about $350 this April 2022 and thought that it's going to be a great long term investment but now it is bricked by the latest firmware version 2.1.4.2. And of course, Netgear told me that my case is not covered with a warranty.
Initially I had an issue with the router that the configuration was reset after every reboot. I had VPN configured and it was annoying to setup it again after every power loss. I opened a support case and the engineer advised me to manually update the firmware to the latest version. After the update the router stopped working at all.
The router is doing the following LED sequence after power on:
1. All LEDs are on for a second
1. 1,2,3,4 LEDs are on for 10 seconds
2. Only Power LED is lit for 30 seconds (for 10 seconds router becomes available via Ethernet but doesn't respond on TFTP requests)
3. Power LED is on and three upper LEDs under the Power LED are blinking for 50 seconds
4. Power LED is on and the second LED with lightning down arrow is blinking for 160 seconds
Then all the sequence repeats.
Maybe there is a chance to restore the router as this behaviour is slightly different from those I've seen on the forum.
Any ideas?

Can you access the modems web page at atl?
What browser did you use to push the FW file?

- Coax cable isn't connected
- Web page is not accessible
- Google Chrome Version 104.0.5112.101 (Official Build) (x86_64)
-
So what happens if you connect the ISP coax cable?
It's the same except the following - now after lightning down arrow blinked other LEDs below is also blinking consequentially like kind of progress bar. But then it reboots again and the pattern repeats.
Ok, Please send DarrenM a PM with the following info seen here:
Or make contact with NG support again whom you talked to before.
Done
- Can't comment on the firmware part of my issues however, after powering my modem of then back on not for anything can I get it working. Experiencing similar issues as mentioned here. Factor reset seems not working since my wifi ID remains same after reset and cannot login into the modem with 192.168.1.1 or www.routerlogin.net tried it hardwired on a PC and on a laptop. For the past 5 hrs I've been at it with no luck. What other options do I have?
Had you updated to v2.1.4.2?
Had the modem been working before?

For the past 5 hrs I've been at it with no luck. What other options do I have?- I did not do any manual updates - not sure if the unit does it automatically? Modem was working fine until today. Only thing I did was unplug power and reconnect, since I've been stuck in a loop of factory resets and power cycling trying to login to the modem. Strange thing is I can get internet access on some websites. I can remotely reboot the modem from ISP app Xfinity. However cannot login into modem and cannot get onto wifi to use nighthawk app to configure it.
Make contact with NG support.
- Ok thanks I will, if I get any updates will feedback.
Someone posted about manually trying to upload firmware should I give it a try? 2 questions from that procedure the file when downloaded is not a .img or .chk it's a .bin. and it mentions unplugging and plugging back in and wait for power light to turn orange that never happens (when does it turn orange?) If you can log into the modems web page long enough to send the .bin file to the modems FW update web page. try it.
Do not unplug the modem from power.
