Smart TV Not Connecting to Wi-Fi? 10 Ways to Fix It
A Smart TV that suddenly refuses to connect to Wi-Fi can be frustrating, especially when streaming apps like Netflix, YouTube, Disney+, or Prime Video stop working.
The problem may come from your router, the TV's network settings, outdated software, a weak Wi-Fi signal, or even a temporary connection error.
The good news is that most Smart TV Wi-Fi problems can be fixed without replacing your television or calling a technician.
In this guide, we'll walk through 10 practical ways to fix a Smart TV that won't connect to Wi-Fi, including solutions for Samsung, LG, Google TV, Android TV, Roku TV, and other popular platforms.
Why Is My Smart TV Not Connecting to Wi-Fi?
Before changing any settings, it helps to understand what may be causing the problem. Common reasons include:
- Temporary router or modem problems
- Weak Wi-Fi signal
- Incorrect Wi-Fi password
- TV network settings becoming corrupted
- Outdated Smart TV software
- Router frequency compatibility issues
- DNS problems
- Too many devices connected to the network
- Temporary streaming service outages
1. Restart Your Smart TV
Start with the simplest solution: restart the television completely.
Do not simply turn the screen off with the remote. If possible, unplug the TV from the wall outlet for around 60 seconds.
Then reconnect the power and turn the TV back on.
A full power cycle can clear temporary memory and network errors that may prevent the TV from reconnecting to Wi-Fi.
2. Restart Your Router and Modem
If your television still cannot connect, restart your internet equipment.
- Turn off your router and modem.
- Disconnect them from power.
- Wait about 60 seconds.
- Reconnect the modem first.
- Wait for it to establish a connection.
- Reconnect the router.
- Try connecting the Smart TV again.
If phones and laptops are also having connection problems, the router or internet connection is more likely to be the cause than the television.
3. Check Whether Wi-Fi Works on Other Devices
Use your phone, tablet, or laptop to test the same Wi-Fi network.
If other devices also cannot access the internet, the problem is probably related to your router, modem, or internet service provider.
If every other device works normally but the Smart TV does not, continue with the TV-specific troubleshooting steps below.
4. Forget the Wi-Fi Network and Reconnect
Your Smart TV may have saved incorrect or corrupted network information.
Open the television's network settings and look for an option such as:
- Forget Network
- Delete Network
- Remove Network
- Reset Connection
Then select your home Wi-Fi network again and carefully enter the password.
Remember that Wi-Fi passwords are case-sensitive.
5. Move the Router Closer to the TV
A weak wireless signal can cause repeated disconnections or prevent the television from connecting at all.
If possible, move the router closer to the TV or reduce obstacles between them. Walls, furniture, metal objects, and other electronic devices can weaken the signal.
You can also test the television temporarily closer to the router. If it connects normally there, Wi-Fi coverage is likely the problem.
6. Try the 2.4 GHz Wi-Fi Network
Many modern routers provide both 2.4 GHz and 5 GHz Wi-Fi networks.
The 5 GHz band can provide higher speeds, but 2.4 GHz generally travels farther and can perform better through walls.
If your TV is far from the router, try connecting it to the 2.4 GHz network.
Older Smart TVs may also have limited support for certain 5 GHz channels or newer Wi-Fi standards.
7. Update Your Smart TV Software
TV manufacturers regularly release firmware updates that can fix bugs, improve app compatibility, and resolve network issues.
Look for a menu such as:
- Settings > Support > Software Update
- Settings > System > About > System Update
- Settings > All Settings > Support > Software Update
The exact menu depends on your TV manufacturer and operating system.
If Wi-Fi does not work at all, some televisions allow firmware updates through a USB drive downloaded from the manufacturer's support website.
8. Reset the TV's Network Settings
If reconnecting to Wi-Fi does not help, reset the television's network configuration.
This removes saved wireless settings and lets the TV create a fresh connection.
The option may be called:
- Reset Network
- Network Reset
- Reset Connection
- Reset Network Settings
After the reset, reconnect to your Wi-Fi network and enter the password again.
9. Change the DNS Server
Sometimes the TV successfully connects to Wi-Fi but still says that there is no internet connection.
A DNS problem may be responsible.
If your TV allows manual DNS settings, you can test a public DNS service such as:
- Google DNS: 8.8.8.8
- Cloudflare DNS: 1.1.1.1
After changing the DNS setting, restart the television and test your streaming apps.
If the original automatic DNS settings were working correctly, there is no need to change them permanently.
10. Use an Ethernet Cable
If your Smart TV has an Ethernet port, connect it directly to the router using a network cable.
A wired connection can provide:
- More stable streaming
- Lower latency
- Fewer signal interruptions
- Better performance in areas with weak Wi-Fi
If Ethernet works perfectly while Wi-Fi does not, the issue is likely related to the television's wireless connection, router configuration, or signal strength.
Extra Fix: Check Date and Time Settings
Incorrect date and time settings can sometimes prevent Smart TVs and streaming apps from connecting securely to online services.
Open the TV settings and make sure the date, time, and time zone are correct.
Using automatic date and time is usually the easiest option.
Extra Fix: Test a Mobile Hotspot
A mobile hotspot is a useful way to determine whether the problem is caused by your TV or home router.
Enable the hotspot on your phone and temporarily connect the television to it.
If the TV connects successfully to the hotspot, the television's Wi-Fi hardware is probably working and your home network settings may be responsible.
Samsung Smart TV Not Connecting to Wi-Fi
On Samsung TVs, start by restarting the TV and router, then open the Network settings and reconnect to your wireless network.
If that fails, look for the option to reset the network configuration and then set up Wi-Fi again.
Also check for available software updates under the TV's Support settings.
LG Smart TV Not Connecting to Wi-Fi
For LG TVs running webOS, restart both the TV and router first.
Then open the Network or Wi-Fi settings, disable and re-enable Wi-Fi, and reconnect to the network.
If the television detects Wi-Fi networks but repeatedly disconnects, test a 2.4 GHz network and check for firmware updates.
Google TV or Android TV Wi-Fi Problems
On Google TV and Android TV devices, restart the television and router, then open:
Settings > Network & Internet
Select your Wi-Fi network and reconnect.
You should also check:
Settings > System > About > System Update
Menu names can differ slightly depending on the manufacturer.
Smart TV Connected to Wi-Fi but No Internet
If the TV connects to the router but says there is no internet access, try:
- Restarting the modem and router
- Testing another device
- Changing DNS settings
- Checking the TV's date and time
- Testing a mobile hotspot
- Checking for an ISP outage
If a hotspot works but your home Wi-Fi does not, focus on the router or ISP rather than resetting the television.
Should You Factory Reset the Smart TV?
A factory reset should usually be one of the final troubleshooting steps.
It can erase:
- Installed apps
- Login information
- Picture settings
- Network settings
- Personal preferences

Frequently Asked Questions
Why does my Smart TV keep disconnecting from Wi-Fi?
A weak signal, router interference, outdated TV software, network congestion, or router configuration problems can cause repeated Wi-Fi disconnections.
Why does my TV see the Wi-Fi network but not connect?
The most common causes include an incorrect password, saved network errors, incompatible router settings, or a temporary TV software issue.
Should I use 2.4 GHz or 5 GHz for my Smart TV?
Use 5 GHz when the TV is relatively close to the router and you want higher speeds. Use 2.4 GHz when the TV is farther away or the signal must travel through several walls.
Is Ethernet better than Wi-Fi for a Smart TV?
Ethernet is often more stable than Wi-Fi and is a good option for 4K streaming, cloud gaming, and TVs located near the router.
Why does Netflix work on my phone but not my TV?
The television may have a network, DNS, app, or software problem even when the wider internet connection is working correctly.
Restart the TV, update its software, reconnect to Wi-Fi, and check whether the streaming app has an available update.
