Check Your Wi-Fi Hardware
If the quick fixes didn’t work, it’s time to examine your network hardware more closely:
Router Compatibility Check
In 2025, router compatibility has become increasingly important as newer Smart TVs adopt advanced Wi-Fi standards:
| Wi-Fi Standard | Compatible With | Max Speed | TV Support (2025) |
| Wi-Fi 5 (802.11ac) | Most TVs from 2018-2022 | Up to 3.5 Gbps | Limited support |
| Wi-Fi 6 (802.11ax) | Premium TVs from 2021-2024 | Up to 9.6 Gbps | Good support |
| Wi-Fi 6E | High-end TVs from 2023-2025 | Up to 9.6 Gbps (6GHz band) | Excellent support |
| Wi-Fi 7 | Newest premium TVs (2025) | Up to 46 Gbps | Limited to newest models |
Check Router Frequency Bands
Many Smart TVs, especially older models, may only support specific Wi-Fi frequency bands:
2.4GHz Network
Longer range but slower speedsMore crowded with interferenceCompatible with most Smart TVs
5GHz Network
Faster speeds but shorter rangeLess interference from other devicesNot supported by some older TVs
2025 Tip: If your router broadcasts both 2.4GHz and 5GHz networks with the same name, try separating them into distinct networks. Some Smart TVs struggle with “band steering” technology that automatically switches between frequencies.
Check Your TV’s Network Settings
Verify Network Status
Most Smart TVs have a built-in network status test that can identify specific connection problems:
Samsung TVs
Settings → General → Network → Network Status
LG TVs
Settings → All Settings → Connection → Network → Network Status
Sony TVs
Settings → Network & Internet → Network status
When running the network test, look for specific error messages that indicate where the connection is failing:TV → X Router: Problem with the local connection between TV and routerTV → Router → X DNS: DNS configuration issueTV → Router → DNS → X Internet: Internet service provider issue
Reset Network Settings
If your TV was previously connected but suddenly stopped working, try resetting the network settings: Navigate to your TV’s settings menuFind the network or connection settingsLook for “Reset Network” or “Network Reset” optionConfirm the reset when promptedAttempt to reconnect to your Wi-Fi network
Important: Resetting network settings will remove all saved Wi-Fi networks and passwords. You’ll need to re-enter this information afterward.

Try Manual Network Setup
If automatic network configuration isn’t working, manually setting up your network can often resolve connectivity issues:
Manual DNS Configuration
DNS (Domain Name System) issues are a common cause of Smart TV connectivity problems. Try setting a manual DNS server: Navigate to your TV’s network settingsSelect your Wi-Fi network or wired connectionFind “IP Settings” or “Advanced Settings”Change DNS setting from “Automatic” to “Manual”Enter primary DNS: 8.8.8.8 (Google’s public DNS)Enter secondary DNS: 8.8.4.4 (Google’s alternate DNS)Save settings and test connection
Static IP Configuration
In some cases, assigning a static IP address to your TV can prevent IP conflicts: First, access your router’s admin panel (typically by entering 192.168.1.1 or 192.168.0.1 in a web browser)Find your TV’s current IP address in the connected devices listOn your TV, go to network settings and change from DHCP/Automatic to Manual/StaticEnter an IP address similar to your current one but outside your router’s DHCP range (e.g., if current is 192.168.1.5, try 192.168.1.200)Enter your router’s IP address as the gatewayEnter subnet mask (typically 255.255.255.0)Save settings and test connection
2025 Update: Many newer routers now support “IP reservation” which allows you to assign a permanent IP to your TV through the router itself, which is often easier than configuring static IP on the TV.
Update Your TV’s Firmware
Outdated firmware can cause Wi-Fi connectivity issues, especially with newer network standards. Here’s how to update your TV:
Online Update Method (If Wi-Fi Works Intermittently)
Navigate to your TV’s settings menuFind “Support” or “System” settingsSelect “Software Update” or “Firmware Update”Choose “Update Now” or “Check for Updates”If updates are available, follow the on-screen instructions
USB Update Method (If Wi-Fi Doesn’t Work At All)
On a computer, visit your TV manufacturer’s support websiteFind your TV model and download the latest firmwareExtract the files to a USB drive (must be formatted as FAT32)Insert the USB drive into your TVNavigate to your TV’s settings menuFind “Support” or “System” settingsSelect “Software Update” or “USB Update”Follow the on-screen instructions to complete the update
2025 Compatibility Note: Many 2025 firmware updates include critical patches for Wi-Fi 6E and Wi-Fi 7 compatibility. If you’re using these newer standards, keeping your TV updated is especially important.
Advanced Troubleshooting for 2025 Networks
Mesh Network Compatibility
Mesh networks have become standard in many homes by 2025, but they can sometimes cause issues with Smart TVs:Position a mesh node near your TV – For optimal performance, place a mesh satellite node in the same room as your Smart TV.Disable node switching – Some TVs struggle when the network hands them off between different mesh nodes. Check your mesh system settings for a “client steering” option and try disabling it.Create a dedicated SSID – If your mesh system allows it, create a separate network name just for your TV to prevent it from switching between nodes.
IoT Device Interference
The average home in 2025 has 25+ connected devices, which can create significant network congestion:Check for bandwidth-heavy devices – Security cameras, smart speakers, and other IoT devices may be consuming your bandwidth.Implement QoS settings – Quality of Service settings on your router can prioritize your TV’s traffic. Look for this option in your router’s admin panel.Consider a dedicated IoT network – Many modern routers support creating a separate network just for smart home devices, reducing interference with your TV.
Wi-Fi Channel Optimization
Wi-Fi channel congestion is even more problematic in 2025 with increased device density:
Download a Wi-Fi analyzer app on your smartphoneScan your area to identify the least congested channelsAccess your router’s admin panelManually set your 2.4GHz network to use channel 1, 6, or 11 (whichever is least congested)For 5GHz, choose channels above 149 if available, as they typically allow higher powerFor 6GHz (Wi-Fi 6E), channels are less congested but have shorter range
