WiFi Set up?

[jhsquires]

I have been using a CAT5 cable for my network connection to my TV. Using a Cable Box wireless box. But the signal is getting slower. I want to try WiFi but I can't seem to be able to turn on the WiFi setting in the setup mode. Could it be because the CAT5 cable is plugged in to the TV. I tried unplugging the cable from the box  and it still won't come up. I can reach the cable plugged into the TV - it is mounted on the wall and can't be reached without taking off the wall... Model - 4K UHD HDR Smart LED TV - 60" Insert other media

@jhsquires Please post what LG TV model you have, and explain what your "Cable box wireless box" is.

LAN/Ethernet cable: unless it is a "loopback" cable, if should not matter so long as the far end (assuming it goes into your router or switch) is disconnected, then you should be able to see what the strongest WiFi signal is listed by SSID in the detected signals by the TV, then attempt to connect to the know SSID of your home router or AP (Access Point).  I am assuming that once the LAN  is disconnected, you can turn the WiFi ON (if turned off). The little WiFi/Bluetooth Combo card in the TV CAN fail due to storms or power spikes, or can just fail electronically inside, and might need replacing.

No WiFi singles show up in the listing - I guess it is time to setup a service call.. It appears that the WiFi is NOT turned on and I can't find any way of turning it on. Thanks for the info.
