How To Reset Network Settings On Samsung Smart TV (2026 Guide)

Resetting network settings on a Samsung Smart TV clears all saved Wi-Fi passwords, wired configurations, and custom DNS entries — then lets you reconnect from scratch. It’s the single fastest fix for most Samsung TV connectivity problems, including Wi-Fi dropouts after a power outage, “unable to connect to network” errors, and the TV suddenly refusing a password it accepted yesterday. The whole process takes under two minutes.

This guide covers the exact menu paths for every Samsung TV generation still in common use (2017–2025 models), plus deeper fixes for when a simple network reset isn’t enough.

What a Network Reset Actually Does

A network reset restores your TV’s connectivity settings to factory defaults. Specifically, it erases all saved Wi-Fi networks and their passwords, clears any custom DNS or IP settings you’ve configured, removes stored wired (Ethernet) configurations, and resets Smart Hub network-related tokens.

It does not delete your apps, Samsung account, picture settings, or any other personalization. It’s a targeted reset — think of it as wiping just the networking slate clean so the TV forgets every connection it’s ever made and starts fresh.

When you should use it: After changing your router or ISP, after a power outage knocks the TV offline, when the TV shows “connected” but apps won’t load, when you get repeated incorrect password errors on a network that other devices connect to fine, or after a firmware update breaks Wi-Fi.

How To Reset Network Settings (Step-by-Step)

The menu path varies slightly depending on your Samsung TV’s model year. Find your generation below.

2022–2025 Models (Tizen OS / Samsung Smart TV Platform)

These are the most current Samsung TVs, including the Crystal UHD, QLED, Neo QLED, The Frame, and OLED lines.

1. Press the Home button on your Samsung remote (the house icon).
2. Navigate to Settings (gear icon) using the directional pad.
3. Select All Settings.
4. Select Connection.
5. Select Network.
6. Select Reset Network.
7. The TV will ask you to confirm — select Reset.
8. Wait for the reset to complete (usually 5–10 seconds).
9. The TV will prompt you to set up a new network connection. Select Network Settings → Wireless → choose your Wi-Fi network → enter your password.

2017–2021 Models (Older Tizen Versions)

1. Press the Home button on your remote.
2. Navigate to Settings.
3. Select General.
4. Select Network.
5. Select Reset Network.
6. Confirm by selecting Reset.
7. Once complete, go back to General → Network → Open Network Settings to reconnect.

Pre-2017 Models (Legacy Smart Hub)

1. Press Menu on your remote.
2. Navigate to Network.
3. Select Network Settings.
4. Select Reset.
5. Reconnect by going back to Network → Network Settings → Wireless or Wired.

Note: If your TV’s menu doesn’t match any of these paths exactly, your model may use a slightly different layout. Check the label on the back of your TV for the model number (e.g., UN55CU7000), then search Samsung’s support site for your specific model’s user manual.

Reconnecting After a Network Reset

After the reset completes, you’ll need to set up your Wi-Fi connection again:

1. Go to Settings → All Settings → Connection → Network → Open Network Settings (or Settings → General → Network → Open Network Settings on older models).
2. Select Wireless.
3. Your TV will scan for available networks. Select your Wi-Fi network from the list.
4. Enter your Wi-Fi password. Use the on-screen keyboard — passwords are case-sensitive, so double-check uppercase and lowercase letters.
5. Select Done, then OK or Connect.
6. The TV will test the connection. You should see a confirmation that you’re connected to the internet.

Pro tip: If your router broadcasts separate 2.4 GHz and 5 GHz networks, connect the TV to the 2.4 GHz network first. It has better range and wall penetration, which matters for a device that’s usually stationary across the room from the router. You can switch to 5 GHz later if you need faster speeds for 4K streaming and the TV is close to the router.

When a Network Reset Doesn’t Fix the Problem

A network reset solves about 70% of Samsung TV connectivity issues, but if you’re still having trouble after resetting, try these deeper fixes in order.

Fix 1: Power Cycle the TV (Cold Boot)

A soft restart isn’t enough. You need to drain the TV’s capacitors to fully reset the network hardware.

1. Turn off the TV.
2. Unplug the power cable from the wall outlet (not from the TV).
3. Wait 60 seconds — not 10, not 30. A full minute lets the capacitors discharge completely.
4. While unplugged, press and hold the power button on the TV itself (not the remote) for 30 seconds.
5. Plug the TV back in and turn it on.

This forces the TV’s Wi-Fi module to reinitialize from scratch. It’s the most effective single fix for Samsung TVs that lose Wi-Fi after power outages or firmware updates.

Fix 2: Set DNS Manually to Google DNS

Samsung’s auto-detected DNS is notoriously unreliable across nearly all model years (2016–2025). Community forums are filled with users who fixed persistent “connected but no internet” issues by switching to Google DNS.

1. Go to Settings → All Settings → Connection → Network → Network Status.
2. Select IP Settings.
3. Change DNS setting from Get Automatically to Enter Manually.
4. Enter 8.8.8.8 as the DNS server.
5. Select OK and test the connection.

If 8.8.8.8 doesn’t work, try these alternatives:

DNS Provider	Primary	Secondary
Google	8.8.8.8	8.8.4.4
Cloudflare	1.1.1.1	1.0.0.1
OpenDNS	208.67.222.222	208.67.220.220

Fix 3: Check Router Compatibility (WPA3 vs. WPA2)

Many routers sold in 2024–2026 default to WPA3 security. Samsung TVs from 2020 and earlier only support WPA2. If your TV sees the network but constantly rejects the password, this is likely the issue.

How to check: Log into your router’s admin panel (usually 192.168.1.1 or 192.168.0.1 in a browser) and look for the security settings under Wireless or Wi-Fi. If it’s set to “WPA3” or “WPA3-Personal,” change it to WPA2/WPA3 mixed mode or WPA2-Personal (AES). Your TV should connect immediately.

Fix 4: Update the TV Firmware

Outdated firmware can cause Wi-Fi disconnection bugs that no amount of network resetting will fix.

1. If the TV has any internet connection (even intermittent), go to Settings → Support → Software Update → Update Now.
2. If the TV has no internet at all, download the update from Samsung’s support site onto a USB drive formatted as FAT32, plug it into the TV, and go to Settings → Support → Software Update → Update Now. The TV will detect the USB update automatically.

Fix 5: Factory Reset (Last Resort)

If nothing else works, a full factory reset will restore everything — not just network settings — to out-of-box defaults.

1. Go to Settings → All Settings → General & Privacy → Reset.
2. Enter your PIN (default is 0000 unless you changed it).
3. The TV will restart and walk you through initial setup again.

Warning: This erases all apps, accounts, and custom settings. Only do this after trying everything above.
