Samsung Smart LED TV - not able to connect WIFI

[gdg2017]

I am able to connect wifi and watch all the internet apps without any issues till yesterday. All of a sudden not able to connect WIFI. When trying to connect thru Network Settings, I am not able to my view home's WIFI connection. It is asking me to connect thru SSID or WPS PIN. I have tried both the options but still not connected.
I have comcast Xfinity router
Please help me with any suggestions

are any of you other devices able to connect to your WI-FI? have you tried power cycling your modem/router?

I am having the same issue with the same model. It is suddenly not detecting any wifi networks. All other devices are connecting well. Could this be a result of the recent update that was pushed to the device?
