Why netgear stopped showing my preferred network?

[MarioHere]

This is really bizarre. I used to use Netgear 64-5G, but after resetting my laptop, all of other networks are showing but the one mentioned above. The mystery here is that my TV is still using the network above?!

There are some certain websites and windows app that arent connecting to the internet. Why the failure only happens to certain websites?

How do I fix DNS errors that occur across all devices in my WiFi network?

I did all of these but still

clear cache in browsers, reset IP addresses, reset proxy, flush DNS, reset router, disabled anti-virus,

Tried to change TCP/IP address to 8.8.8.8 but kept getting " "the dns server is not a valid ip address" error"

I want their support on why Im not seeing my preferred network and why Im getting DNS messages

What NG product is this? Router? 

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Try enabling IPv6 on the router?
