It's incredibly frustrating when your Samsung TV refuses to save your Wi-Fi password or network settings. You enter the correct information, it connects for a moment, but the next day, you're back to square one, re-entering the password. This is a surprisingly common issue, but the good news is that it's almost always fixable with a few straightforward troubleshooting steps. This guide will walk you through the most effective solutions, from simple resets to more advanced tweaks.
## Understanding the Problem
When your Samsung TV fails to save network settings, the issue is rarely a hardware failure. Instead, it's typically caused by a corrupted network cache, an IP address conflict, outdated firmware, or a compatibility issue with your router's settings . The TV stores your network information, but this data can become outdated or broken, especially after a router change or an ISP update . Another common cause is a known software bug in some Samsung TV models that prevents the password from being saved .
## Step-by-Step Solutions
### 1. Perform a Targeted Network Reset
The first and most effective step is to reset only the network settings. This clears all saved Wi-Fi credentials, IP settings, and DNS configurations without affecting your apps, picture settings, or account logins . Think of it as giving your TV's network memory a clean slate.
For most Samsung TVs from 2016 onwards, the steps are simple :
1. Press the **Home** button on your remote.
2. Navigate to **Settings** (the gear icon) > **General** (or General & Privacy).
3. Select **Network**.
4. Choose **Reset Network**. You will need to confirm your choice .
5. Once the reset is complete, go back to **Open Network Settings** to reconnect to your Wi-Fi .
**Important:** Have your Wi-Fi password ready, as this reset erases it. For 2021 and older models, the path is similar: **Home > Settings > General > Network > Reset Network** .
### 2. Perform a Full Power Cycle
If a network reset doesn't solve the issue, the problem might be in the RAM-level network state that a menu reset can't touch. A full power cycle, also known as a "cold boot," can clear this .
1. Turn off your TV and unplug it from the wall.
2. Unplug your router and modem.
3. Wait for at least **60 to 90 seconds** .
4. Plug your modem and router back in and wait for them to fully restart.
5. Plug your TV back in and turn it on. Then, try reconnecting to your network.
An alternative method for a "cold boot" is to press and hold the **Standby key** on your remote until the TV reboots and the Samsung logo appears .
### 3. Check Your Wi-Fi Password and Router Band
It sounds simple, but Wi-Fi password issues are a leading cause of connection problems.
- **Password Complexity:** Some Samsung TVs have difficulty handling Wi-Fi passwords with special characters like `!`, `$`, `&`, etc. The TV's software may not parse these correctly, causing it to reject or fail to save the password . If possible, change your router's password to only include alphanumeric characters (letters and numbers) to see if that resolves the issue.
- **Router Band Settings:** Most modern routers broadcast on both 2.4 GHz and 5 GHz bands. Some Samsung TVs only work with 2.4 GHz networks . If your TV struggles to connect, try connecting it specifically to the 2.4 GHz band. For better control, give your 2.4 GHz and 5 GHz networks different names (SSIDs) on your router so you can choose which one to connect to .
### 4. Update Your TV's Firmware
Outdated software is a known cause of network instability . Samsung frequently releases updates that fix bugs and improve performance. Make sure your TV is running the latest firmware version.
1. Go to **Settings > Support > Software Update**.
2. Select **Update Now**.
3. If your TV cannot connect to the internet to download an update, you can download it from the Samsung website onto a USB drive and install it manually .
### 5. Manually Configure DNS Settings
Sometimes, your TV can connect to Wi-Fi but not to the internet. This is often a DNS error. Manually setting a public DNS server can bypass this problem .
1. After reconnecting to your Wi-Fi, go to **Settings > General > Network > Network Status**.
2. Select **IP Settings**.
3. Change the DNS setting from **Get automatically** to **Enter manually**.
4. Enter **8.8.8.8** (Google's DNS) or **1.1.1.1** (Cloudflare's DNS) as the primary DNS server .
### 6. Last Resorts: Factory Reset and Router Check
If nothing else works, consider a full factory reset of your TV. This is a last resort, as it will erase all your settings, app data, and account logins, restoring the TV to its out-of-box state . You can find this option under **Settings > General & Privacy > Reset** (the default PIN is usually `0000`) .
If even a factory reset fails, the problem may lie with your router. Test the TV on a different network, like a mobile hotspot. If it works, the issue is with your home network's configuration, and you may need to contact your Internet Service Provider .
