CAX30 - Disables internet on network name change.

Helllo,

 

I have a CAX30 that I purchased from Costo (and also exchanged as of yesterday), that when I complete my network setup in the nighthawk app with a wifi network name change, disables my internet and the modem then becomes unreachable despite devices being 'connected' to the wifi. If I reset the device and run a new nighthawk app setup, leaving the network name as default, I will be able to connect. The issue is I have many devices using a network name/password that I created. This has now occurred on 2 CAX30 cable modems on Xfinity internet.

Device: NG Nighthawk AX2700 CAX30 Cable Modem

 

ISSUE: Name change disrupts router from connecting to the internet.

 

-Name change disrupts all devices' ability to reach the internet.

-Internet works if the network name is not changed.

-This exact same issue has occurred on 2 CAX30 cable modems.

 

my network name - 'my.network.name'

Cannot connect to the internet on either band, despite being connected to the modem.

cannot reach the router admin page after the network name change.

The Nighthawk app no longer connects after the network name change.

 

ISP: xfinity

What happens if you change the ssid name through the browser and not the app?

Re: CAX30 - Disables internet on network name change.

Unfortunately the exact same thing.

 

I've tested this now on both modems...

I have no idea why this is causing such an issue, but I will probably end up having to just return the modem if it can't handle simple network name changes... 

 

 

If i leave it as the default netgearxx network, i have no issue.

this occurs on both the app and the browser.

When it goes through the setup it auto updated to the most recent. It’s literally out of the box.

Their auto update doesn't always work. Its why we ask what version its on

Re: CAX30 - Disables internet on network name change.

So I've updated my firmware to the version 1.4.10.10

 

the wifi network is still not working, but now the hardwire connections are working. Previously even ethernet-connected devices were disabled. I have my Roku and a PC hardwired, and they are now receiving network connection after updating the wireless network name to "my.network.name" but wifi is still not reaching the internet.

I also cannot remote into my hardwired PC from a wireless connected device, so it is affecting the internal network as well.

Re: CAX30 - Disables internet on network name change.

What is the sample SSID name your changing too? I would avoid using any special characters. 
Try a simple SSID name like CAX30.

Use a simple password as well for now. Simple 8 to 10 alpha only character password. 

Make sure Smart Connect is enabled. 

 

Let us know your results.

Re: CAX30 - Disables internet on network name change.

posted sample network name in original post.

 

This isn't a 100 dollar modem. setting a network as cax30 doesn't solve any problems.

also, I already posted about the default netgear name working.

 

If this modem can't handle a "." in the name, then it needs to be returned. This is amateur stuff.

Also this network name previously worked without issue. Infact it was named this until last week when it randomly reset and then network name reverted back to orginal netgearxx name and now name changing the network name does not work.

This issue is now continuing on 2nd modem.

Re: CAX30 - Disables internet on network name change.

Asked about what custom SSID name you are trying to set.

 

Some special characters are not supported in the SSID name. I know space in between words works. A (.) may not be. I never use any special characters in the SSID name. So if your wanting to use a period in the SSID name then either remove it or find different modem that supports having a (.) in the SSID name. 

 

Try "my network name" instead with spaces in between.


Good Luck.

Hi,

 

I also stated that I previously had a name that included "." on this exact modem.

It's also 2022. A modem that doesn't support a "." in the name is probably not worth buying.

 

Thank you for your input though.
