LG 55UF6450-UA won't connect to Wi-Fi network.

Question

Hi, I have an LG WebOS Smart TV that after the last firmware update the Wi-Fi Connection stop working properly. When I try to connect to my network, it will instantly disconnect or it will freeze my TV.

Model: LG 55UF6450-UA (bought it on November 2015)

Firmware: 03.16.00

Also, I don't know if it is relevant but my TV is a US version that now I have it with me in Costa Rica, Central America.

I've tried everything posted on the internet and forums:

- Connecting to my cellphones hotspot (worked for about 5 min the first time I try it and then stop working and would work again when I tried to reconnect).

- Change the DNS to google's DNS. (Once I was able to do it but didn't fix the issue, and also first I need to be able to connect to a network for the TV to enable the option for changing manually to static ip's).

- Doing factory reset won't fix it.

- Changing the Country/Region/Time zone won't fix it.

- Changing to manual time won't fix it.

- Can't do the downgrade procedure posted on this forum for two reasons: because you need to be able to connect to the wifi or via ethernet and it isn't working, and also I can't find an older versión of my firmware.

I am pretty sure that I need to downgrade or even just do a fresh installation of the actual the firmware, but I can't find the right way to do it. Maybe with an LG service remote? but again, I need to first get on my hands a working firmware version for my TV right?

Any recommendations?

Hi @cali086

In other threads on the forum people have reported similar issues and have found it was due to faulty wireless models, in their case it was easy enough to find replacements on the likes of eBay.  See if you can find the relevant threads and you may find if the same applies to yourself.

@George Hofmeister I guess you meant "Faulty Wireless Modules". I did see some vidoes on YouTube about how to replace these. There was one I saw recently that showed one being removed, he brushed the dust off the ribbon cable connector, and put it back in. Not sure if that is a common problem, or if the WiFi modules are totally failing electronically (i.e. failed component inside). Obviously brushing the dust off is NOT going to fix that! Of course the OP could be right that the firmware upgrade has broken the functionality (especially if it has tightened up standards for use on another country, as is the case here - channel seperation, power output etc.)?

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?

Might be a hardware/software fault.

Try to reset your wifi router as well. Connect again (Use WPS if you have )if it connects and works fine, then great.

If it freezes, look up in the router admin panel - if it shows tv as connected assign it a permanent ip address. Might help.

Solution 2- 

Can you try and connect a lan cable from the router to the tv for testing purpose.

If it works get a wifi range extender with ethernet port. 
Connect the extender to  wifi network and lan cable from the extender to the tv’s lan port.

I won’t recommend opening the tv up.

Ciao @ cali086

In altri thread sul forum le persone hanno segnalato problemi simili e hanno scoperto che era dovuto a modelli wireless difettosi, nel loro caso è stato abbastanza facile trovare sostituti come eBay. Vedi se riesci a trovare i thread pertinenti e potresti scoprire se lo stesso vale per te stesso.

I had the same problem on a lg 49 I solved it once it connects to the wifi from the router assigns statito ip to the tv

      Hello,
      Is there any way of installing an usb gigabit network adapter on a webos smart TV?  The builtin wired adapter is only 100mbps (on a 2000$+ TV, shame  on you LG!!!)  while the wifi (N) is very poor, with the router at 1m from TV it only gets half the bandwidth of the wired network. Anyway the wired network  maxes out near 100mbps but I need more bandwidth as I have 4k video content with bitrates grater than 100mbps which I cannot stream without stuttering to TV through XPLAY/PLEX. 
      Kind regards,

      Update failed because software version is earlier than the version installed on the TV.
       
      5.80.50 version installed on the tv now. But i want to return 04.70.55. Is this possible? Can anyone help me about this? Additionally, i am in Turkey. I want to install real official firmware. Can anyone send me the right firmware for me to install 04.70.55 ( I dont want to have language problems. I see the LgDTVUpdater package RU version)?

      Ciao, possiedo un tv lg 55uh650v era impostato su posizione Russia e dopo all'aggiornamento del firmware versione 05.30.45 non riesco più ad usare le app in quanto non riesco a accettare i termini contrattuali. Ho provato a cambiare il DNS e a collegarmi tramite cellulare ma non ho ottenuto nessun risultato. Ho provato più volte ad eseguire il reset di fabbrica ma nessun risultato. Inoltre ho notato che la versione del mio firmware non è presente sul sito LG Italia mi chiedevo se fosse possibile tornare ad un versione firmware inferiore, potresti aiutarmi?
      Hello, I own a TV lg 55uh650v was set to Russia position and after the firmware update version 05.30.45 I can not use the app anymore because I can not accept the terms of the contract. I tried to change the DNS and connect via mobile but I did not get any results. I have tried several times to perform a factory reset but no results. Also I noticed that the version of my firmware is not on the site LG Italy I wondered if it was possible to return to a lower firmware version, could you help me?

      I am in the process of moving my WiFi to a 4G carrier. I was testing the 4G modem and needed to move back to the Broadband modem for a day - I found that the BB password was not kept on the LGWEBOS TV.  Similarly when I moved back to the $G modem I had to re-enter that. This TV is the only device that I have which does not remember passwords
      Is there a way of placing a support ticket for a change to the OS

      I have an LG 43UK6300PLB TV, connected via Wifi to my home network.
      Now, this may be an abnormal setup, so i get it may be unique, but i have two main wifi hotspots in my home. One from my BT Smart Hub, but i also have a pair of TP-Link Deco P9's running in Access Point mode to offer wider wifi coverage in a mesh setup.
      I'd obviously prefer for the TV to connect to the P9 Network as the nearest AP is nearer to the TV that he BT one, but when i do the LG Smart App for some reason cannot see the TV, which it should as the Mesh network is running in AP mode (so alongside the BT DHCP).
      Can anyone provide any tips?

      I'm trying to open up a web browser on our new 43UM750 OPLA set. On this webos site the instructions are clear "To open the web browser click on the home button on the remote, and select the button on the screen that appears as 3 diagonal dashes" they start.
      But when I push my home button, there is no sign of those three dashes.
      What am I doing wrong? Or are those instructions  out of date? Or is there something not mentioned there that I need to do to make those three dashes appear?

      Hello everyone!
      I've just bought the new LG 55SM8600PLA with the latest update (AirPlay 2 and HomeKit support) and having many problems with it.
      The moment I plug the Ethernet cable on it, the TV starts spamming my entire network with Zeroconfi packages (captured with WireShark) resulting on all devices becoming unresponsive and slow.
      Here is screenshot of me pinging a wireless device with latency higher than 500ms, the moment I turn off the TV, ping goes to normal ~1ms (all cable):

      This happens with all devices on my local network. Using a couple of Asus RT-AC68U routers.
      Does this happens to any of you?
      Thanks!
