Clarification Request
LG OLED tv internet connection

I use Hyperoptic internet 150 Mbps. On my computer and phone, signal is strong but on my LG OLED 65 tv connection speed was low. Ethernet increased it to 20mbps then I moved the router to the living room closer to my TV (without LAN Cable connection) and suddenly internet connection speed went up between 70mbps to 120mbps on 5ghz.

For those with LG OLED tv, I recommend you bring the router towards the TV, use 5ghz because it's stronger than Ethernet or LAN/Cable connection .

Note this is only applicable to LG OLED tv.

Listening mode

Now with just a single hair left on my head i went here and abracadaver i was happy about that. Even though the manufacturer should know this, but apperantly they do not, the tv states in shared app that you need to turn listening mode off if the wifi is unstable. IT WORKS LIKE A CHARM.

Went from about 5-20 Mbps to 150-190Mbps after turning listening mode off. Now i can stream movies without wondering if i got 1 kg of butter in my eyes.

Thank you stranger for this tip. And booooooo at the LG support for not knowing this in advance that this is a known problem.

Posting here as well as down the thread for people to know early without to need to read all threads

Clarification sought

Hello Norwaynorth
Could you be a little more clear by what you meant by ' turning off the listening mode in Shared App' where can i find it on the TV.

Ref the sentence "... the tv states in shared app that you need to turn listening mode off if the wifi is unstable. ..."

Answer
I check a few things.

1. The router firmware is current.
2. I test with another DNS such as 8.8.8.8 and 4.2.2.1
3. The TV firmware is current.

There are bum routers out there, try another and for TVs the distance is about half that of a common laptop. Figure 20 feet for many sets.

thank you

I appreciate you took the time to reply! I'm using the internet provider's router, and it doesn't give good quality wifi even for other devices. But I didn't know if the fact that after disconnecting and then reconnecting to the wifi on the tv led to a consistently good connection until the tv is turned off and then on again meant that the problem was on the tv side of things and not the router/modem side.

I'll look into the troubleshooting options you mentioned, thanks!

While I might agree it's the TV

These SmartTVs tend to have poor WiFi so distance is an issue almost all the time. The real fix is to forget the TV's smart bits and use some Roku, Amazon Fire TV or such stick or box. I find the WiFi in such to be superior every time.

Try the free things first and if you insist on using the smart TV apps, consider a powerline link to the router. Here's an example kit:


The remote part has WiFi as well which may give you better WiFi than what the ISP supplies. It also has 2 Ethernet ports so you can get a much better connection and experience on the Smart TV.

I agree, it's the tv's issue

I'm noting the same wifi issues with my C7P LG OLED set. Wifi speed is initially really low (<1 Mbps) unless power TV off, and reconnect wifi. After reconnecting wi-fi by selecting an alternative network and then switching back, I get 25+Mbps. Problem is, this speed doesn't appear to be holding at that rate. But after a lot if experimenting, I'm convinced it's not the router since I can achieve a25+ Mbps speed and testing signal with my phone at the same spot shows a reasonably strong signal as well. I was considering getting a wifi repeater to try and better my signal in the room with the TV, but I really don't think that's where the problem is. I really think the TV's wifi is not connecting and working properly. Hopefully LG will look into a firmware update for this issue (Please LG!!)

Right, makes sense

Yeah it just doesn't seem to make sense to me that it'd be on the router side since I have multiple other devices that connect to the wireless network just fine. Also when I first got the tv I didn't have this issue, it happened a few weeks after getting it. Also if it was the router it seems odd that disconnecting and then reconnecting on the tv leads to perfectly fine internet.

Unfortunately powerlink doesn't work with the electrical setup in my apartment.

Since the usual fails.

Your next move is a warranty call. They fix or you ask for refund.

- Collapse -
PS. I forgot to note this. May be repeating.

Just because other things connect fine this is not a sign the TV has failed. Some routers are just incompatible and we know smart TV wifi has always been worse than laptops and phones. But it appears you have dismissed the router so this leaves with no choice but to make it a warranty issue.

Exact same issue....

I too have extreme WiFi issues with my c7. Shaw came over today and we played around with several different setting but eventually swapped out the Hitron Router. Picked up about 40Mbps over the old unit. I have a 49" Bravia I use as a monitor that sits along side the 65" c7. www.fast.com reports 170Mbps on the Sony while only 25Mbps on the LG. Not a router issue, apparently an issue with LG. I'm not going to try boost the signal as it is already as strong as it can get. I will try Ethernet cable but really LG, you've an issue here. Don't let people down who spent their hard earned cash on this beautiful tv aside from it's few flaws. No resolution at this time. Will contact re-seller and LG for comment.

Tough issue. Makers may not be implementing high speed WiFi

I can only think of a few reasons.

1. Cost.
2. UHD 4K content from Netflix calls for a number that you wrote in your post (Surrey!)

Example at https://help.netflix.com/en/node/306

So the maker may be putting in exactly the required speed and nothing more.

Answer
Do you?

Use the screen share or LG TV Plus App? If so, go into the Screen Share splash screen and check that the 'Listen Mode' isn't set to on. If it is, turn it off.

That worked for me. If not, I turned off the advertising cookies, deleted the browser history, restarted the TV and removed all the connected Apps. I tested it after each of these and it didn't work, but just in case it was a combination of more than one.

Genius

That's it!

Turned off listening mode and am now getting the same speed on the TV as on my other stuff.

Thank you!

Turn off listening mode!

I turned off ''listening more'' from the screen sharing app and speeds went from 1 to 29 mbps! I get 39 mbps from all my other devices but its good enough for netflix and youtube etc. thanks guys!

FIXED

Turning off "Listening mode" as referenced in other posts here solved the problem for me as well.

LG OLED55B7T

Having to reenter your password every time is ridiculous. LG need to fix their software. It is 4 months since the original post. There must be many many people blaming this on their Wi-Fi gear or Netflix.

Variety of Issues

Feel like there's a variety of issues here. Mine most certainly isn't the router, and it isn't the tv capping off at a certain speed.

It is extremely slow, unusable, and then when I disconnect from the wifi in the settings, and then reconnect, it's fast again. I have a new router, it's the same issue. This also wasn't the case when I first bought the tv, but started happening a few weeks in. It must be some bug in the wireless network adapter in the tv.

As it stands now I've moved and with a new living room layout can plug straight from the router to the tv. No more issues now that I'm not using wifi. But I will say having to re-enter my wifi password every time I turned on the tv in the past was a real nuisance.

The bug exists

Sabe situation over gere. My tv model is a 55in B7 and at first Wi-Fi was great. After a few weeks wifi became very poor. If I connect to a second WiFi network (normally I switch from my 2.4G network to 5Ghz network or vice versa) it becomes usable again. I think it became like this after one of the software updates but I’m not quite sure...

It's not the router

I have the same issue. The Netflix app on my LG OLE TV reports speeds <= 2Mbps while all other other wireless devices on the network report 25+ Mbps. I then have to disconnect the TV from the wifi and re-connect. Once the TV re-connects, I'm back at 25+ download speeds. This usually lasts for several days, but I start noticing picture quality issues, so I have to do the routine over again. My router is less than 20 feet from the TV, with nearly 100% signal strength. It seem so happen on both the 2.4 and 5 Ghz bands. It's got to be the TV. I'm close to running Ethernet cables through the room to see if it helps.

Just fixed another one. Not the router

But the ISP. I changed to another DNS (the google one) and the TV smartened right up. Try that.

Listen Mode may be your problem!

Just wanna throw in one more response on "listening mode" in the screen share app, which was absolutely my issue. Average speed with it on was about 2-3 Mbps, and after turning it off, every test is over 100. Turn it off, and hopefully lg will work on this issue.

Solved!

Thank you, this fixed the issue!

Go into screencast app and turn off listening mode, my speed instantly went from 3Mbps to 160! Like another user mentioned, you can point the browser app to fast.com to measure the speed.

Thanks again! I was about to give up and go wired

Thank you!!!

Thank you so much! This fixed my issue with my LG OLED TV... Had this issue for ages and just never got around to fixing it. Can't believe such a feature could cripple the wifi speed. I went from 1mpbs to 80mpbs!! Massive difference. Every time i launched into Netflix and tried to load something. It would be 0-10% for ages. It would be on the lowest quality... Now! It loads instantly! No more buffering issues, or slow wifi speed connections!

Thanks again bud!!

LG OLED tv Wireless Issue - network card

I have an OLED65C7P. TV was under extended warranty and they replaced the network card. Apparently there's an issue with the network cards on these TVs.
