C7800 WiFi not showing up
I have done all the things, called netgear and ISP.
My WiFi cut out randomly, fur solid white lights, no WiFi at all.
WiFi button does nothing.
Hardwiring in gives me internet access but when accessing router it says that my WiFi is enabled. Nothing is being broadcasted, please help.
I have power cycled, factory reset, changed every setting.
Is my hardware broken? How did that happen?

Have you disconnected the coax cable from the modem and from the power wall outlet?
I am having this exact same problem!
I tried disconnecting power and coax, still nothing. Did the radios die?My guess is yes. NETGEAR blames my ISP, ISP blames NETGEAR... I'm out $300+ and NO ONE will help. I'm not paying for Tech Support on something I bought 15 months ago. My ISP was at my house within a day and I'm now BACK to renting a router/modem.
I was trying to save money, in the long run I spent double (rental is $10 per month x 15 months = $150, cost of NETGEAR device that failed in the same 15 months=$300+)
What the hell NETGEAR, I used to trust your company implicently. Turns out this model is riddeled with KNOWN problems and NETGEAR just keeps taking peoples money and blaming ISPs.
NEVER buying a NETGEAR product again and I will be sure to make sure EVERYONE I know and am related to wont support this company.
WHAT
A
JOKE
YES
I have done all forms of power cycling, restoring factory settings, etc.
The WiFi simply does not work any more, when testing the line I have a perfectly fine connection and can get internet via ethernet.
NETGEAR IS A JOKE
Looks like we're in the same boat.
I bought mine september 2019, wifi just quit last night.
Netgear wants $50 for support now after I paid $300+ for their equipment not two years ago? that's ludicrous.
by chance, have you switch ISPs lately? Are you on Cox by any chance?
If the wifi radios are not working,even after a factory reset. You can just disablle them in the UI. Then connect up any other wifi system to the C7800 and continue to use the C7800 as your modem and router as a alternative suggestion. There are better wifi systems out there that are way better than the wifi thats on the C7800.
That would be a last resort option, I'm sure.
However, I've been searching threads and the same thing happened to another user last night as well. Something funky is going on...MY theory is this:
Something with ISPs thinking we need a firmware update causes the decive to think it's being DoS attacked.
This happens beacuse there WAS NO UPDATE FIRMWARE RELEASE, for some reason ISP pushed it anyway (NETGEAR does NOT send firmware updates, only ISP for this model). So after repeated attempts and subsequent failures, the modem disables WiFi in a effort to lock out potential Denial of Service attack.
I can't get NETGEAR to admit this, and the ISP swears they didn't send an update although I saw it with my own two eyes when I hardwired (ethernet) to the modem and access the router through it's diagnostics. I had access to the page for a second and then it went completely black with green lines and lettering saying "Firmware Update in Progess" or words to that effect.
NO ONE will own up to this Firmware Push and frankly IDGAF anymore...
I've read that people with the same unit are doing that, I plan on using it as a trade in on a new modem and router.
I will never buy/use a NETGEAR product again. Which is sad because I've used them for 18 years.
I recommend getting into separete modem and router units. Having combo units is ok but when something happens you loose more than you expect. If you have separate units, then there is a bit more control over your system. Especially FW updates which you can't control on modems or modem combo units like the C7800. You still have the modem and router portion work which for this case you can keep using it.
You might contact the ISP and see if they can downgrade the FW on the modem if it had been recently updated to see if this changes anything. The ISP will need to do this.
