Issues with LG TV and weird WiFi behaviour

I recently bought a new router (Unify Dream Router) and after a couple of weeks of struggle, I managed to set it up with my ISP's VDSL connection (FFTC) using a third party modem in bridge mode (NETGEAR D6400).

Everything seemed to be working fine until I realised I couldn't open the Netflix app on my LG Smart TV. After a bit of investigation, I realised nothing except for YouTube and the Browser was working. Just to make this clear: the WiFi connects fine, I can access all websites through the LG Browser, and I have no issues with YouTube, but nothing else works.

All the regular streaming apps fail to open and, most importantly, the LG Content Store fails to load. Before I fixed my network, the tv was working fine. If I switch to my phone's hotspot, everything works fine.

Things that I've tried:

  • factory resetting the tv
  • leaving the tv unplugged to delete cache
  • using google's DNS on the TV
  • using a wired connection 

Having said so, I am so lost that I would be happy to try anything again.

Ignore my comment about the Netgear? You obviously ned a VDSL modem! Try disabling IPV6 protocol on both, as you only really need IPV4 in most home networks. Older TV sets might be a problem trying to negotiate IPV6.

      My 50UT80506LA LG WebOs TV does not support my office security camera system via wifi to TV. We need (gCmob app) in list of app.
      By Ramesh Chand Vishwakarma
      It is unprofessional on part of LG TV that they do not resolve the basic issue of adding app gCmob in their app store.

      I can't connect my office camera via Wi-Fi to LG-TV. No body in LG TV technical team is proactive in resolving the issue of customer. They are more happy to befool the customers, rather than looking for technical solution through wider thinking.
      Please talk to you top management and make a visit to our office to understand the customers plight..
      Please respond to customers needs.

      Wifi issue
      By loafty
      Tv  connects to wifi and can stay connected for couple of days then I will switch tv on and internet (wifi) will be disconnected so go to connect up again and tv can't find any networks so turn off and unplug from power wait 5 to 10 minutes then plug all back in go to wifi settings might be lucky to find my network select and enter password and works again. Only thing is I got a different modem from internet provider and they have told me that the modem is working fine but I have never had an issue like this with tv before. Tv states wifi is turned off but I can't find anywhere that I can turn wifi on in the tv, does anyone know ?? Tried calling LG didn't get much help at all, I am 71 years old and just want my tv working the way it should so hope someone can help. Thanks

      Magic Remote Pointer and other Issues
      By Speedemon
      I have a UK6300 LG TV. It has always worked faultlessly. However it now will not show the pointer unless I restart it and then it only there of only for 20 seconds and then it is gone. The LAN cable notification constantly disconnects and reconnects. The Web Browser no longer opens on my selected page. The Software version is the latest and when I tried to manually update the software in case the auto update got corrupted it will not recognize the USB drive as having the software on it. The software browser version is 05.50.15.
      Any ideas what to do. I have two other LG TV's and all work perfectly.

      How to accept a WiFi connection from a Linux PC desktop using the remote
      By makem
      I have a  LG OLED55C14LB WebOS TV in the same room as my xubuntu desktop computer and router.

      I have installed Gnome Network Displays on the Linux PC and both machines are on the same 5G network.

      When I connect the PC to the TV via WiFi the TV puts up a 'cancel' option and no option to connect. The Network display app only has an option to 'Return' which closes the connection.

      If I do nothing and wait the connection times out and returns to the TV program. The TV is obviously waiting for permission to connect.

      I cannot see any way to 'accept' the connection via the TV remote. Can anyone tell me how to accept the connection?
      In addition, is it possible to have the TV remember the WiFi password? Passwords are complex nowadays and it is a pain to keep having to input it. This make casting your desktop a chore.
