Hi @George Hofmeister,
Thanks for your comments. I forgot to include that this exact same issue happened first last year and in that time, from reading on this forum, I thought it was like you said, a faulty wifi module. We changed the module and the issue persisted, and it was until LG released a new firmware that it got fixed. I think that the only solution is going to be to wait for LG to release a new firmware again and after that I will have to disable auto update. I am also trying to report the issue directly to LG to see if they can get the fix sooner.
I've read also that this type of issues are very common on al brands of Smart TVs, but I am pretty sure my model is one of the worst. Its OS has always been super buggy, lost of strange behaviors, some time wifi didn't connect automatically, some times simple link just won't work with my sound bar, etc., and after the first year of having it the motherboard died, so I had to change it for a used one but in working condition since LG doesn't sell new parts or they charge more than the TV cost, crazy right?
