C7500 firmware issue?
About couple weeks ago, I am starting to have issue with my network, and now that my 5G is just gone (not visible). When I am looking into the C7500 webpage, I see that my firmware version is V1.01....

Is that I need to change my firmware? And how should I change?
You can't. Only your ISP can do that.
Start with trying to fix this:

What is that "issue"? Just the vanishing 5 GHz?
What tells you that? All wifi clients or just some of them?
What does the 5 GHz LED look like?
While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.
You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

You might like to search there for messages related to your problem.
In the meantime you could visit the support pages:

Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.
Check for various troubleshooting tips.
You may have done this already. I can't tell from your message.
I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.
Is my ISP the Internet Service Provider (COX)?
the 5G LED is good, solid white light.
When I say not able to find, I am using my home device (ie. computer, cellular phone), none of them is able to see the 5G network ID. Only 2.4 network ID.

Factory reset the modem and setup from scratch using a wired PC and web browser at 192.168.1.1.
Please give feedback to the linked items that were give as well.
Did reset the modem a couple of times. By pushing the button at the modem, and remotely from the ISP service. No change.
From ISP side, it is reporting no issue with the network. When go into modem's page, I see connection are good for 2.4G and 5G, showing the network ID name and etc.
But, when I use the home device (ie. computer, cellular phone), I can only see the 2.4G network ID, no 5G network ID.
My 5G network is still saved in my computer as I had it connected before. Nothing changed. But, now it is telling me that my 5G network is not available.

Last resort would be to try a 30-30-30 reset on the modem. If this fails to bring back the 5ghz radio, then it's probably busted.
Couple of options, Disable all wifi radios on the modem and install a wifi system in AP mode connected to the modems LAN port.
Or configure modem only mode and install a new external wifi router system and continue to use the modem for ISP internet services to the external wifi router system.
Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.
