LG TV Wi-Fi connection problem

Mar 3, 2018 5:23AM PST

Hi I'm trying to find out if a problem I have is a problem of my LG 49U67V TV or my modem's problem.

Some times ( irregular pattern)  when I try to connect to some kind of web service (browser,  YouTube, Netflix),  I can't connect or the speed is too slow. My TV is connected via Wi-Fi.

When check the Wi-Fi and internet connection trough the settings Evey thing looks OK. At the same time my Android phones connect superbly and if I measure my internet speed via from phone or PC everything is OK.  I found 2 solution for  this

A.   either restarting the modem and then everything is OK the connection superb etc.

B. Going to settings, disconnect from my router and reconnect (you know adding again the router password). Then everything is back to normal. 

The TV does not seem to have any other issue.  

I've tried to go back to factory settings. I've noticed the problem again. In irregular pattern it appears no standard time or pattern of appearance.

Could it be that my modem router is the problem?  I have this modem for over 3 years. 

I will try another to be sure. LG here said "we can check your TV but if we don't find anything you (me that is)  will have to pay for pick up and delivery expenses.

Clarification Request
Mar 3, 2018 7:00AM PST

The TV seems to be connected during this problem. Just it does not stream data from the internet or it does in low lie speeds. Netflix speed test shows it at really low speeds or disconnected while in settings it seems connected. Strength of Wi-Fi signal, superb

Things to check.
Mar 3, 2018 5:46AM PST

1. Distance is 20 feet or less to router.
2. The TV firmware is up to date (ask LG as this check is not standardized.)
3. Change the DNS to (see google on how)
4. Get wired. WiFi is often too troublesome for smooth operation.

possible solution
Mar 4, 2018 5:42AM PST

First of all, thank you for answering my question. Based on your answer I did some web search and learned useful things I did not know such as bands, channels, frequencies, Wi-Fi analyzers , guest networks etc.
I think I found a solution which seems to work. I turned off the "Quick Start " setting in the Settings menu in a previous Q&A session.

I also changed my Wi-Fi security protocol from wpa to wpa/wpa2 (don't know what that means) although I supoosevthis was irrelevant since the TV did see the network but just couldn't establish sufficient data streaming.

Finally I changed date and time from web based to manually set as also suggested in the previous link

First day today without a lagging internet on my TV. Hopefully I found it.
I'll wait a few days more before I call this question answered.

Genius. Looks like turning off "Quick Start" did the trick. I also changed my 5GHz channel to 36 but are now changing it back to Auto Channel. If the results change I'll let you know.

WiFi Bad - Wired Good
Dec 28, 2019 2:08PM PST

Turning off Quick Start+ on LG TVs will indeed reset the WiFi adapter and may temporarily fix the problem. But it's not a permanent fix, it will simply reduce the frequency of the issue by restarting the wireless adapter.

There are two main fixes if the TV's WiFi keeps disconnecting (while other devices work fine):
1) Return or repair the TV.
2) Hard wire the Ethernet - Run an Ethernet CAT5/6/7 cable to the TV.

WiFi connectivity is a common problem with Smart TVs. And, WiFi connection problems are a waste of time. In the end, the best option, whether the TV WiFi works or not, is to just use a hard wire Ethernet connection to the TV.

If you want a faster, more responsive (quicker to browse), and more reliable connection, hard wire the Ethernet.

Take a look at your router
May 16, 2018 7:31PM PDT

I've just bought an lg uj6525 and noticed that even though I have a 100Mb connection, the tv wasn't able to use more that 1.5Mb... it was struggling to load a 480p YouTube video... after trying several methods to fix this issue, I came across this solution, which is simple: I have 2 wi-fi frequencies working at the same time: 2.5ghz and 5ghz. All my devices are set to work with the 5ghz frequency, for it's the one capable of reaching the highest speed. It turns out that even though the tv is able to see and work with both of them, 5ghz is the sluggish one. Just switched to the 2.5ghz network and it was all good. Still can't reach 100Mb, however, it swings around 50Mb, which is more than enough for 4k

I found the solution
May 25, 2018 1:01AM PDT

Hi guys,
I found a possible long-time solution for the connection issues which seem to be more of an issue on the 5Ghz wifi networks. I took a look at the channel my wifi was operating on and it was automatically choosing something above channel 100 (i think it was 102). After having this problem on and off for about 3 months now I just for the hell of it switched automatic channel selection off and set it to channel 36 manually. That which has been 1 MBit immediately changed to 65 MBit on the TV!!! No restart, no clearing of cookies, no Quick Start+ off, nothing.
I'd really appreciate if you guys could test that on your systems Happy
Good luck!

Sep 22, 2018 6:59AM PDT

Buongiorno from Italy,
I had the same issue and following your precious experiences I fixed the problem as follow :

1. Change the DNS to (see google on how)
2. Change the wi fi network to 5Ghz
3. Switch from automatic channel on the wi fi to manually channel 36

The speed changed immediately from 1mb to 70 on the TV. Thank you all for sharing on this log book.

Problem Solved
Jun 20, 2018 2:12PM PDT

Never thought I’d say this but I had a great experience with customer service. I called, they had me run through:
1. Quick start - off
2. Changed country from us to Canada, back to us and restart
3. Reset tv
4 reset modem

No avail. They sent a repair guy out with a new os and WiFi modulator.

Worked, the tv needed updates but all is good. No charge for work done.

At 12 inches you can wire it with Ethernet which is a better connection and every case I've worked given a faster better Smart (?) experience.

LG TV Wi-Fi speed
Jul 15, 2018 9:47PM PDT

I experience the exact same problem!

My LG OLED55C7V-T wirelessly connects at maximum speed and everything is fine for a day or two, but then the connection speed slowly degrades until content streamed from Netflix, Youtube, etc. becomes blurry. Checking the connection speed confirms a problem. (Every other device connected to my home network works fine and the signal strength in my TV room is excellent.)

I searched for a solution on the Netflix website and found a fix: Switch off the TV completely (not standby), wait a couple of minutes and switch on again. (Sounds like Microsoft's solution for every problem: reboot. Happy ) After that everything is back to normal - for a while.

This is irritating and driving me nuts. The question: is this a Netflix problem or a quirk of the TV model? (And by the way - I'm running the latest software on ALL my devices AND my router is perfectly configured.)

Any other suggestions? Other Netflix users? Or LG users?

This sounds similar to PC WIFi woes.
Jul 16, 2018 7:09AM PDT

The little WiFi card gets warm and speed drops off. Either arrange for repair or exchange or think about a wired connection. Or an external WiFi to Ethernet device.

I don't think this will be fixed with a setting.

LG TV WiFi Connection
Jul 29, 2018 8:32AM PDT

Okay so I went back and forth with this issue.
Tried to connect via WPS (no good), password (originally worked but then failed).
Finally turned off quick start.
Changed date/time to manual (had me set up automatically in another time zone).
reset router and tv. (unplugged and reconnected).
turned on both and selected router name, inserted password.
connection and streaming restored.

good to know
Mar 7, 2020 8:51AM PST

I have had fits with my wifi and LG. So glad to hear others are annoyed regularly too. I'm trying your Lexus 2801 next time. Honest to God, the most expensive tv ever, and can't stay wifi connected. Asus (my router company) suggested changing password and doing any updates for my router, and that helped. I found out that the asus router can't be accessed with MY information, but only with the 2017 id/pass set up by my volunteer Geek, which thank goodness he left me on a piece of notebook paper. Now is that weird? Oh, I love the information about hard wire Ethernet to the tv. My router is in the basement and the tv is in the living room. It routes wifi to everything in the house, anywhere: Kindle, smartphone, fire tv, even next door and outside! -- but the LG can't hold on to it. They'll fix it. Wait quietly!

I have a brand new 2018 LG 55UK6500AUA, recently coming from a 2017 LG 55UJ6540 which had similar problems but not as bad. I have been having issues where it would not connect, then it would connect but netflix wouldnt load, then when it would load it would only stream 480p, youtube wouldnt stream 4k.. I never knew if when i turned my TV on i would be able to watch tv that day. I tried all the things in the comments and nothing worked. I turned off quickstart+ I went into my router settings and made my 2.5ghz network separate from my 5ghz network and changed the mode on the 2.5 from B/G/N to G/N and now its working flawlessly. I hope it stays this way.
