What WiFi protocols and security is your router access points using… check its compatible with your TV. You might need to enable legacy wifi and security modes possibly. Also make sure your not limiting frequency bands.. modern wifi protocols needs access to 2.4 5 and 6 GHz and will negotiate the optimum band for a client.
I have had problems with LG wifi implementations on some of thier TVs not connecting to Ubiquiti wifi acess points in the past. I use Ethernet for myvLG TVs now… we have three.
I had thought of firmware updates but was reluctant given the the TV is 14 days old and the router 3 days at the time I asked the question. (Yes, I am aware that these thing could have manufactured some time ago with older firmware).
Still getting round to implementing your suggestions but as a temporary, but in light of your experience, probably permanent fix I had a spare 10ft ethernet cable kicking about in the just in case box. Problem solved.
For future knowledgebase i will have a play with updates, security protocols etc when I have a spare day or 3 knowing what technology is like and report back.
