Fix “LG TV Keeps Disconnecting from Network” — Wi-Fi drops, unstable connection, apps buffering

Technician avatar Technician
Hi! We’ll get your LG TV keeps disconnecting from network issue fixed so streaming is stable again instead of dropping every few minutes.

First I need a quick picture of your setup so we can target the right LG TV Wi-Fi fixes:

• Which LG TV model / webOS version do you have (rough year is fine)?
• Are you using Wi-Fi or Ethernet for the TV — and is the router in the same room or in another room / floor?
• When the LG Smart TV loses internet connection, do you see a message like “Wi-Fi is turned off”, “network disconnected”, or specific LG TV network error codes (e.g. 105 / 106)?

Also, do other devices (phones, laptops) stay connected to the same Wi-Fi when the LG TV drops the network, or do they also disconnect?
Customer
It’s a few-years-old LG Smart TV on webOS (not sure which version). The TV is on Wi-Fi, no Ethernet cable. The router is in the next room, maybe 6–7 meters away through one wall.

Every 10–15 minutes the LG TV loses internet connection. Sometimes it says “Wi-Fi is turned off”, other times it shows network error 105 and asks me to reconnect. My phone and laptop stay connected to the same Wi-Fi the whole time, so it really seems like just the LG TV keeps disconnecting from Wi-Fi.
Technician avatar Technician
Got it, that helps a lot. When an LG TV keeps disconnecting from Wi-Fi while other devices are fine, it’s usually one (or a mix) of these:

• The TV’s Wi-Fi is right on the edge of range, so any small fluctuation makes it drop the wireless network.
• The TV is stuck hopping between 2.4 GHz and 5 GHz on a combined SSID, which causes random network disconnects.
• Power-saving options like Quick Start+ or SIMPLINK / HDMI-CEC can make the LG TV Wi-Fi module sleep and not wake up cleanly.
• Buggy settings (cached IP/DNS, old firmware) cause LG TV network errors 105 / 106 even when the router is fine.

We’ll start with basic resets, then move on to webOS network settings, router tweaks, and finally what to do if the LG TV Wi-Fi keeps dropping because of a weak or faulty Wi-Fi module.
Customer
Okay. For now the TV connects to the same network name as everything else, I didn’t split 2.4 and 5 GHz. Signal icon on the TV usually shows full bars. It disconnects more often when we’re watching Netflix or YouTube in 4K. Sometimes reconnecting works right away, other times the LG TV won’t detect any Wi-Fi networks for a minute or two.
Technician avatar Technician
Perfect, we’ll treat this as a classic LG Smart TV keeps disconnecting from network case and get a clean baseline first.

Step A — Power-cycle & clean reconnect
1) Turn the LG TV off, then unplug it from power for a full 60 seconds. At the same time, unplug the router and modem for 30 seconds, then power them back on and wait until Wi-Fi is fully up.
2) On the TV go to Settings → Network → Wi-Fi Connection, select your home network, choose Forget, then add it again from scratch and re-enter the password.
3) If your router lets you split bands, create a dedicated 2.4 GHz SSID (e.g. “Home-2G-TV”) and a 5 GHz SSID (e.g. “Home-5G”). Try connecting the TV to the 2.4 GHz one first — many older LG TVs disconnect from 5 GHz when the signal isn’t perfect.
4) Make sure the TV isn’t right next to a thick wall, fridge, or metal cabinet; even moving it or the router a bit can stop intermittent disconnects.

After doing this “reset & reconnect”, stream something for 10–15 minutes and tell me if the LG TV still keeps dropping the Wi-Fi connection.
Customer
I did the full power cycle for both TV and router, then set separate 2.4 and 5 GHz networks. The TV is now on the 2.4 GHz SSID. It stayed connected longer than usual, but after about 30 minutes of Netflix it still disconnected and showed network error 106. My phone on the same Wi-Fi didn’t drop at all.
Technician avatar Technician
Good test — that tells us the router and password are fine, but LG TV network settings likely need tuning.

Step B — Adjust webOS network & power settings
• Go to Settings → All Settings → General → System → Time & Date and make sure the TV has the correct time, time zone and region. Incorrect time can sometimes cause LG TV internet connection problems with streaming apps.
• Next, open Settings → Network → Wi-Fi Connection → Advanced Wi-Fi Settings and set DNS manually to a stable server like 8.8.8.8 (or whatever your ISP recommends), then reconnect.
• Under Settings → General → Devices → TV Management, temporarily turn Quick Start+ and Auto Power Off off. These can make an LG TV Wi-Fi connection unstable after standby.
• If you see any “Eco” or power-saving network options enabled, turn them off so the TV doesn’t aggressively sleep the Wi-Fi module.

After applying those changes, restart the TV from the power button (not just Home) and test again. If the LG Smart TV still keeps disconnecting from Wi-Fi, we’ll look at router QoS, interference, and firmware on both sides.
Customer
I set the correct time and region, changed DNS to 8.8.8.8, and turned off Quick Start+ and the auto power options. After a restart, Netflix and YouTube ran longer without errors, but later in the evening the LG TV lost network connection again while another family member was gaming online on a console. The TV showed “Wi-Fi is turned off” and I had to toggle Wi-Fi off/on to get it back.
Technician avatar Technician
That behavior fits with Wi-Fi congestion — heavy traffic from the console can make the router push older devices off first, so it feels like the LG TV keeps dropping the network.

Step C — Optimize router for LG TV streaming
1) Log into the router and check for a firmware update. Install it if available; many brands have fixed Smart TV Wi-Fi stability bugs via updates.
2) In the Wi-Fi settings, set the 2.4 GHz band to channels 1, 6, or 11 manually, and keep channel width at 20 MHz. This reduces interference and can help when an LG TV keeps disconnecting from 2.4 GHz Wi-Fi.
3) Turn on QoS or Streaming / Media mode and mark the LG TV’s MAC address or IP as high priority so it doesn’t lose out to the console.
4) If it’s at all possible, try running an Ethernet cable to the TV (even temporarily for testing). When an LG TV keeps losing Wi-Fi connection but works perfectly on Ethernet, we know the TV itself is fine and it’s purely wireless stability.

Once that’s set, stream in the evening while the console is in use again and tell me if the LG TV still disconnects from network or if it holds the connection better.
Customer
I updated the router firmware and set the 2.4 GHz channel to 6 with 20 MHz width. I also enabled a “Media Streaming” QoS profile and added the TV’s MAC address as high priority. Running an Ethernet cable just for testing made everything rock solid — no disconnects at all. On Wi-Fi it’s much better now, but I still saw one LG TV Wi-Fi disconnect after a couple of hours of watching live sports.
Technician avatar Technician
Great — that confirms the TV hardware is okay and tells us we’re chasing the last bit of wireless instability rather than a dead Wi-Fi module.

For that remaining issue:
• On the TV go to Settings → All Settings → Support → Software Update and make sure the LG webOS firmware is fully up to date. Some updates specifically mention fixing LG TV network connection problems.
• If there’s a lot of nearby Wi-Fi (apartments, neighbors), try the 5 GHz band again but keep the router and TV as close as possible — 5 GHz can be more stable for HD/4K streams when the signal is strong.
• Keep the router out of TV cabinets and away from large metal objects, and move cordless phones or baby monitors away from it; these can cause LG TV Wi-Fi to drop randomly even when other devices appear fine.
• If your router has a setting like “Airtime Fairness” or “Band Steering”, try disabling it temporarily; some LG models behave better without those features.

After this, many people find their LG TV no longer keeps disconnecting from Wi-Fi, especially during long streaming sessions.
Customer
I updated the TV firmware and moved the router out of the TV cabinet. I also disabled Airtime Fairness. On 5 GHz with the router closer, the LG TV Wi-Fi connection has been stable for a few hours now, no more “Wi-Fi is turned off” messages or error codes. Ethernet is still the most stable, but Wi-Fi is finally usable again. Anything else I should do so it doesn’t start disconnecting in a few weeks?
Technician avatar Technician
Nice work — now we can lock these changes in so LG TV keeps disconnecting from network doesn’t come back every month.

Step D — Keep LG TV Wi-Fi stable long-term
• If it’s practical, leave the TV on Ethernet; if not, keep the router and TV within strong Wi-Fi range — same room is ideal.
• Keep your dedicated SSIDs (2.4 and 5 GHz) and avoid putting dozens of low-priority devices on the same band as the TV.
• Leave Quick Start+ disabled if it ever causes the LG TV to lose Wi-Fi after standby again — it’s better for the TV to start cleanly.
• Once a month, quickly check for router and TV firmware updates so bug fixes for Wi-Fi and streaming get applied automatically.
• Take a photo or screenshot of your working LG TV network settings and router Wi-Fi/QoS settings so you can quickly re-apply them after a factory reset or new router.

With that in place, your LG Smart TV should stay connected reliably, and if you ever notice the Wi-Fi dropping again, you’ll know exactly which settings to review.
Customer
Got it. I’ll keep the router closer and leave the TV on the dedicated Wi-Fi network — Ethernet if I can manage the cable. After all these changes, the LG TV isn’t disconnecting from Wi-Fi anymore and streaming feels much smoother. Thanks for walking me through everything.
Technician avatar Technician
You’re welcome — glad we could get your LG Smart TV staying online reliably again.

Summary: To fix an LG TV that keeps disconnecting from network, power-cycle TV and router, forget and reconnect Wi-Fi, set a stable DNS server, disable Quick Start+, update webOS firmware, and tune your router’s channel, QoS and distance. If the TV works flawlessly on Ethernet but not Wi-Fi, focus on wireless range and interference. If you ever get stuck again — random errors 105/106, “Wi-Fi is turned off”, or constant buffering — you can open a chat with an expert and we’ll trace the problem with you live.
Customer
Perfect, everything is stable now and I actually understand what affects the LG TV network connection. I’ll keep those screenshots of the settings in case we change routers later.

Quick answer: the accepted fix

Accepted fix when an LG TV keeps disconnecting from network: power-cycle TV and router, forget and reconnect to Wi-Fi, set a stable DNS server, disable Quick Start+, update LG webOS firmware, and tune router channels and QoS so the TV has a strong, steady wireless or Ethernet connection for streaming.

Why LG TVs keep disconnecting from Wi-Fi (range, congestion, firmware, power settings)

Most LG TV keeps disconnecting from network issues come down to a combination of Wi-Fi range, congestion and software. Even if other devices stay online, the TV’s Wi-Fi antenna and drivers may be less tolerant of weak signal or crowded channels, which shows up as LG TV Wi-Fi dropping, error 105/106 or “Wi-Fi is turned off”.

Having both 2.4 GHz and 5 GHz under one network name, power-saving options like Quick Start+, outdated webOS firmware, or router features like band steering can also make an LG Smart TV keep losing internet connection. Separating bands, placing the router closer, updating firmware and turning off aggressive sleep modes often makes the LG TV network connection stable again.

How to tell if LG TV disconnections are from the TV, router, or ISP

To narrow down an LG TV keeps disconnecting from Wi-Fi problem, start with simple tests:

First, connect the TV with an Ethernet cable directly to the router. If all the disconnects vanish, the apps work, and speed tests on the TV are stable, the issue is almost certainly Wi-Fi range or interference. If the LG TV still drops the network on Ethernet, then webOS, TV firmware or a failing network module are more likely. Finally, if every device in the house loses internet at the same time as the TV, your router or ISP connection probably needs attention as well.

LG TV keeps disconnecting from network — quick troubleshooting tips

Reset TV and router, clean up Wi-Fi settings, then tune DNS, channels and QoS.

Fast path: power-cycle your LG Smart TV and router → forget and reconnect to your Wi-Fi network → separate 2.4 GHz and 5 GHz SSIDs → disable Quick Start+ and set a reliable DNS server → move the router closer or try Ethernet → enable streaming QoS and pick a clear Wi-Fi channel so the LG TV Wi-Fi connection stops dropping during Netflix, YouTube and live sports.

FAQ

Why does my LG TV keep disconnecting from Wi-Fi or the network?

An LG TV that keeps disconnecting from network usually means the wireless link is marginal or the TV’s network settings are out of sync. Common causes include weak signal through walls, crowded Wi-Fi channels, band steering between 2.4 and 5 GHz, power-saving features like Quick Start+ confusing the Wi-Fi module, or outdated firmware. Any of these can make the TV drop Wi-Fi while other devices stay connected.

How do I stop my LG Smart TV from dropping the Wi-Fi connection?

To stop an LG Smart TV from disconnecting from Wi-Fi, power-cycle TV and router, forget and reconnect to the network, separate 2.4 GHz and 5 GHz SSIDs, set a reliable DNS (such as 8.8.8.8), disable Quick Start+, and update the TV’s software. Placing the router closer to the TV and enabling QoS or streaming priority for the TV also helps a lot with long HD/4K sessions.

Is 2.4 GHz or 5 GHz better for an LG Smart TV?

For older models or TVs farther from the router, 2.4 GHz can be more stable because it travels through walls better, even though it’s slower. For newer LG TVs in the same room as the router, 5 GHz often works better for 4K streams because it’s faster and less crowded. If your LG TV keeps disconnecting from 5 GHz Wi-Fi, try 2.4 GHz first, then move the router closer and retest 5 GHz.

When should I call LG or replace my router for LG TV Wi-Fi issues?

If your LG TV keeps losing internet connection even after resets, firmware updates, DNS changes, and testing Ethernet, it may be time to contact LG support — especially if the TV also fails to see nearby networks or disconnects on every router. If the TV is stable on other networks but drops only on yours, then upgrading to a modern Wi-Fi 5/6 router with better coverage and features is usually the right move.
