I know this post is old, but I noticed some fairly recent posts where people are having the same issue. LG did a shoddy job with the WI-FI module inside the TV, resulting in the ribbon cables getting crimped. There's a fairly easy solution for probably most of the people on here, although I'm sure it's a different problem for some.
