Wifi Network Missing but LAN works
So my Wifi network just disappeared and does not show in the available list anymore. However the LAN still works.
My other devices are able to see the wifi and connect without any problem.
I have Reset PC
Updated Wifi Adapter Card
Reset and changed router name
Disabled Sleep Option in wifi adapter properties
I dont know what else to do.

It could be a number of things causing this. Usually in cases like this only one device has a problem, so you need to figure out what device isn't working. A couple things you can try are connecting other devices to the router (got a mobile phone?) and taking clients (PC, phone, etc.) to a coffee shop or friend/neighbor/relative's house, etc. to try them on a different WiFi network. If they work elsewhere now you have known good clients and you can blame the router.
If you have a phone you can also try putting it in hotspot mode and connecting the PC to the phone if your carrier will let you. Be careful doing that. It's easy to go through a lot of mobile data fast on a computer. If there are any open WiFi networks near your house you can also try connecting to those to test your PC. They might have one of those web login screens like you see in hotels, but if a login page comes up at least the WiFi is working even if it won't let you on the Internet without a password.
It's possible it could be interference, but usually that just causes poor performance and doesn't make the router totally disappear. Interference bad enough to do that would result in no networks being visible at all if you're close to the router and would not be caused by other peoples WiFi and 2.4 & 5Ghz devices. For that kind of interference something needs to be broken, like some sort of electrical equipment that isn't working right and spews out radio waves at far higher power than WiFi gear.
If you're renting a gateway from Comcast don't be shy about asking them to swap it out. Swapping gateways tends to be one of the first things they want to try. I'd try another WiFi client first if you can just to make sure you're not wasting your time doing a swap.

Have you tried power-cycling / re-starting the device ? No joy ? Try hard resetting the device to factory defaults by pressing and holding in the recessed reset button on the rear (or use the WPS button if it doesn't have a reset button hole) for 30 seconds. This can sometimes clear up some weird behavior issues. You will lose any customized settings, and they will need to be re-configured from scratch if you do the latter.
Good luck !
