What to Do When LG TV Keeps Disconnecting From WiFi?

Tweak Your Router’s Settings

The router is the central device controlling Wi-Fi signals in your home network. So, it’s a good starting point for troubleshooting wireless connection problems with your LG smart TV.

Here are a few tweaks worth trying:

  1. Switch the wireless mode from dual-band to a single 2.4GHz or 5GHz band. See if your TV maintains a steady connection on one band.
  2. Change the WiFi channel on the router to the least crowded option in your area for reduced interference. Channels 1, 6, or 11 typically work best for 2.4GHz networks.
  3. Turn off 20/40 MHz coexistence if your router supports this feature. This prevents interference between WiFi bands.
  4. Adjust the channel bandwidth to 20MHz for improved performance on 2.4GHz networks.
  5. Switch the wireless security protocol to an option supported by your LG TV model – WPA2 is universally reliable.

You can access your router’s configurations through its manual or try logging in through a web browser using its default gateway IP address.

Update Your LG TV’s Software

Like other smart devices, LG rolls out periodic software updates for its smart TV lineup to fix bugs, patch vulnerabilities, and improve performance. If your particular Wi-Fi disconnecting issue stems from a software glitch, updating to the latest firmware version can resolve the problem.

To check for an available update on your LG TV:

  1. Using your TV remote, select the Settings icon from the home screen to access the main settings menu
  2. Go to the Support tab > Software Update > Check for Update
  3. If an update is available, select Start to begin the process – your TV will automatically download the firmware and install it on restart.

The software update can also enhance your TV’s wireless drivers. So, even if no major issues are flagged in the changelog, keeping the firmware up to date is still good practice when facing Wi-Fi problems.

Adjust Your TV’s Wi-Fi Settings

Diving into your LG TV’s connectivity settings gives you a few additional troubleshooting checks to identify why the WiFi keeps dropping:

  1. Scan for available WiFi networks through your TV to confirm the issue is not caused by your SSID being invisible to the television.
  2. Check the detailed connection information (typically under Network > Wi-Fi connection info) for parameters like IP address, DNS, and subnet mask. If they show all zeros or keep changing, it indicates the TV is struggling to maintain a WiFi assignment from your router.
  3. Forget all saved wireless connections using your LG TV’s settings and directly re-enter the credentials instead to eliminate conflicts.
  4. Switch off Auto IP configuration in your TV’s Internet Protocol settings if this feature is enabled. Relying on DHCP from the router directly can improve stability.
  5. Adjust power saving settings to keep WiFi active even in standby mode for constant connectivity instead of your TV’s wireless adapter going to sleep.

If none of the above helps, consider factory resetting your LG TV to eliminate any problematic configurations triggering the disconnects.

Disable Quick Start+ and SIMPLINK Features

Disable Quick Start+

The Quick Start+ feature keeps key TV components powered on even when switched off to enable faster rebooting. But this standby power drainage can disrupt Wi-Fi connections.

Under General settings, toggle off Quick Start+ and check if this stops connectivity drops when the TV is idle.

Turn Off SIMPLINK

SIMPLINK allows controlling HDMI-connected devices like soundbars via the LG TV’s remote. But issues in the interaction canmanifest as Wi-Fi glitches.

Under General settings again, switch off SIMPLINK if enabled. See if removing this HDMI-CEC integration stabilizes wireless performance when using connected equipment.

Disabling these two features eliminates some potential complications that could interfere with steadier Wi-Fi connectivity on your LG smart TV.

Set Time and Date Settings Manually

The automatic or NTP time/date synchronization capabilities on your LG TV could also get misconfigured over time.

So, navigate to the Time & Date menu within the General settings. Turn off the Auto Synchronization or Internet Time Sync options to prevent external sources from updating these settings on your TV.

Instead, configure the time zone, current time, and date accurately and completely manually based on your region and preferences.

Locking down uniform timings ruled by the TV system alone removes inconsistencies that may hinder connectivity with your routers and services, which rely on accurate time-syncing between devices.

Analyze Your ISP Speeds

Speed Up Your Mobile Internet

Sluggish internet speeds often translate to Wi-Fi drops on bandwidth-heavy smart TVs, especially when multiple devices are simultaneously connected to the network.

So, examining your actual broadband performance can reveal a lot.

Run through ISP speed tests directly wired to your router and then over Wi-Fi connected to the router. Compare bandwidth metrics across both tests, such as download/upload speeds, latency, and packet loss numbers.

If Wi-Fi speeds lag way below your plan limits or the wired speeds, router placement, congestion, or range issues will likely interfere. Upgrade to a higher tier if your plan’s bandwidth maxes out quickly with multiple devices online.

Relocate Your Wireless Router

One quick physical fix is to move your WiFi router closer to your LG TV for stronger signal reception. Breaking line-of-sight barriers in between also boosts connectivity:

  • Shift the router off the floor onto a higher point like a bookshelf
  • Reposition away from heat sources that can interfere, like vents or direct sunlight
  • Bring it to the same room as your LG TV if placed too far away earlier
  • Remove thick walls or metallic furniture pieces creating a barrier between the router and television

After relocating the router, connect your LG TV to the WiFi network again and check if distance improvements resolve the disconnecting symptom. Maintaining the WiFi router near bandwidth-guzzling devices gives a quick stability boost.

Install a WiFi Extender

If no amount of router reorganizing resolves weak signal issues in your LG television’s spot, installing a mesh WiFi range extender is usually the next best solution for blanketing that area with boosted coverage.

For the extender placement itself, here are some tips worth keeping in mind:

  • Position the extender in a mid-point spot in a straight line between your router and the LG TV struggling with WiFi reach.
  • Keep it away from potential interference sources mentioned earlier.
  • Try elevating the extender or adjusting antennas to catch stronger existing WiFi signals from your main router.

Setting up a compatible extender/repeater to relay your router’s WiFi network makes your connectivity closer to the affected LG TV. Just take care to choose an adequately powerful enough model rated for your network coverage size and device count.

Change the DNS Server IP Address

The Domain Name System (DNS) server that converts domain names to IP addresses can sometimes get overloaded or perform poorly, causing connectivity issues.

LG TVs use your router’s default DNS server by default. Switching to a reliable alternative DNS server like Google’s 8.8.8.8 address in your TV’s IP settings menu can help stabilize internet access.

This sidesteps dependency on your existing DNS server by routing requests through Google’s fast public DNS service instead. Just make sure to clear cached app data/restart apps that use internet access, like streaming platforms, after updating the DNS server IP.

Setting the DNS to 8.8.8.8 often resolves problems with DNS lookup failures that manifest as Wi-Fi drops or inability to launch internet-connected apps.

Upgrade Your LG TV’s WiFi Adapter

If your LG TV’s inbuilt wireless adapter seems severely lacking in reception strength no matter what you try, fitting a dedicated high-performance WiFi USB dongle or adapter can directly solve connectivity problems forever.

Consistent speeds above 150 Mbps let you comfortably stream, cast, and Airplay without interruptions. Important things to factor in while picking an upgrade WiFi adapter:

  • Latest WiFi standards like dual-band 802.11ac for the most reliable connections under different conditions
  • High-gain adjustable external antennas to amplify signals
  • WPA2 encryption supports at least
  • The extra range for flexibility in the router and TV positioning after installation
  • Compatibility specifically for LG TV hardware and webOS platform for seamless plug-and-play connectivity

Investing in a long-range directional outdoor antenna kit for your LG TV can also help pull in your home’s WiFi signal more reliably if going the adapter route.

Switch to Ethernet

Try Ethernet Instead of WiFi

Suppose you have connection problems across all wireless devices in the house. In that case, WiFi issues likely stem from external interference or fundamental limitations of router signals permeating your home’s construction materials and layout.

In that case, switching to wired Ethernet connectivity is the most failsafe permanent option for keeping your LG TV online.

Run a long Ethernet cable from your primary router/switch directly into your television’s LAN port. This physically bridges the connectivity gap without involving temperamental over-the-air WiFi links.

Ensure the routers and switches in your connected path provide sufficient ports and the right PoE standard if the run is longer.

Consider Mesh WiFi Instead of One Router

In many cases, implementing a mesh WiFi system with dedicated access points around your home can be a neater alternative to Ethernet.

This offsets WiFi dead zones arising from household obstructions or distance by creating a smoothly flowing mesh blanket of multiple coordinated wireless nodes.

Your LG TV (and other disconnected devices) stays locked into the nearest node with the strongest signal as you move around instead of relying on one distant router.

So check out mesh WiFi kits from Eero, Netgear Orbi, Google WiFi, and more to permanently wave goodbye to WiFi drops!

Call in a Professional

As a last resort, don’t hesitate to call in a professional if all else fails. Getting assistance from a network administrator, your internet provider’s technician, or TV/electronics repair services can help uncover or solve long-standing wireless connectivity problems.

Whether it’s faulty equipment or complex settings tweaks, their technical expertise, special hardware tools, and on-location assessment can quickly diagnose what’s amiss and devise the right troubleshooting solution for your environment.

Regular maintenance checks from professionals can also help curb potential networking issues down the road before they affect multiple devices. However, keep costs in mind if going down this route.

Conclusion

Maintaining a stable WiFi connection is crucial for reaping the full benefits of LG’s impressive smart TV capabilities, like streaming, casting mirroring, and smart home control.

Hopefully, the tips above help resolve the issues causing your LG television to drop its wireless connection abruptly. Getting to the root factors like distance limitations, software bugs, bandwidth bottlenecks, or interference ultimately allows you to troubleshoot connectivity for good.
