So a very strange thing happened.  My TV now can connect to my modem (Wi-Fi 2.4G as shown in my modem setting. ) and as soon as connected to internet, I got a notification to update my firmware to 05.10.10. 

Everything is fine but internet is a little slow when playing 4K videos from YouTube.

I have a LG 49SK8000 and I have the same problem but my TV has not been updated it happened over the night.  I have done the same things but it was not effective.

Here is a quick list of the facts/my observations/things I have also tried.

• None of the other devices in my house have this problem.
• The TV is in the same room as the router
• The TV can connect to 2.4GHz and it's very slow
• I have factory reset both the router and TV
• I have tried various 5GHz channels and different a/ac/n
• I have tried disabling/enabling quick-start
• I have tried connecting via WPS
