Model Samsung UE40EH5307K This is a classic LED TV with Smart TV support, still widely used in many homes. Despite its age, the device can stream content from the network, but initial wireless connection setup often raises questions among users. Proper network configuration allows access to online cinemas, a browser, and system software updates.
The connection process may vary depending on the type of router you're using and the firmware version installed on your device. In some cases, the standard procedure may not work on the first try due to encryption protocol issues or IP address conflicts. Connection stability directly affects the quality of high-definition video playback.
In this article, we'll cover every setup step in detail, from selecting the connection type to troubleshooting common errors. You'll learn how to manually enter network settings correctly if the automatic search fails, and which hidden settings may require your attention for stable operation.
Equipment preparation and compatibility testing
Before you begin setup, make sure your wireless router is working properly and is transmitting a signal within the TV's range. Model UE40EH5307K Supports Wi-Fi 802.11a/b/g/n standards, meaning it's compatible with most modern routers operating in the 2.4 GHz and 5 GHz bands. However, for this series of TVs, the preferred frequency is 2.4 GHz, as it provides better signal penetration through walls.
It's important to know your wireless network password in advance, as the system will require it at one point. If you haven't changed your router settings, the password may be located on a sticker on the bottom of the device. For complex corporate networks or hidden SSIDs, you'll need to know the exact network name and encryption type.
Make sure your TV has a Wi-Fi adapter installed if it's not built into the case. Some EH series models require an external USB adapter. WIS12ABGNX or a similar, Samsung-certified module. Without this module, wireless connection will be unavailable, and a LAN cable will be required.
- 📡 Check if the Wi-Fi indicator on your router is on.
- 🔑 Write down your network password so you don't have to look for it during setup.
- 🔌 Make sure the USB adapter (if using an external one) is firmly inserted into the port.
- 📺 Place the TV no more than 10 meters away from the signal source for the first setup.
⚠️ Note: Some dual-band routers may broadcast a network with the same name (SSID) for both 2.4 GHz and 5 GHz frequencies. If your TV isn't seeing the network or is constantly losing connection, try temporarily separating the network names in your router settings or force the router to use 2.4 GHz only.
Automatic wireless network setup
The easiest way to set up your internet connection is to use the automatic search for available networks. To do this, turn on your TV and wait for the operating system to load. Press the button Menu or M on the remote control to bring up the main menu.
Using the navigation buttons, go to the section Net (Network). In the window that opens, select Network settings (Network Settings). The system will prompt you to select the connection type: wireless or cable. Select Wireless (Wireless) and press the confirm button Enter or Center.
The TV will begin searching for available access points. This may take 10 to 30 seconds. In the list that appears, find the name of your home network (SSID). If the network is password-protected, there will be a lock icon next to the name. Select the desired network and press the Login button.
A virtual keyboard will appear on the screen. Use the navigation buttons to enter the Wi-Fi password. Be careful with capitalization: A And a — these are different symbols. To switch between upper and lower case, use the special button on the on-screen keyboard or the button T on the remote control, if it is programmed.
☑️ Check before connection
After entering the password, select the button Ready or ConfirmThe TV will attempt to establish a connection. If all parameters are entered correctly, you will see a message confirming a successful connection. The system may prompt you to check for software updates—confirm them to ensure the network module drivers are up-to-date.
Manual configuration of IP and DNS parameters
In situations where automatic connection is impossible, or there is a connection but the internet is not working, manual configuration is required. Often, the problem lies in incorrectly received addresses from the router's DHCP server. To resolve this issue, select "Network" in the network menu. IP settings and switch the mode with Automatically on Enter manually.
You will need to enter the IP address, subnet mask, gateway, and DNS server. The TV's IP address must be in the same subnet as your router, but not the same as other devices. For example, if your router's address 192.168.0.1, then the TV can be assigned 192.168.0.150.
Pay special attention to the DNS server field. Providers often provide their own DNS, which can be slow or block some resources. Using public DNS from Google or Cloudflare can significantly speed up Smart TV response times.
| Parameter | Meaning (Example) | Description |
|---|---|---|
| IP address | 192.168.0.150 | Unique TV address on the network |
| Subnet mask | 255.255.255.0 | Determines the size of the network |
| Gateway | 192.168.0.1 | Your router's address |
| DNS server | 8.8.8.8 | Google DNS server address |
⚠️ Note: If you don't know the exact IP address of your router (gateway), check the connection settings on any other device (smartphone or laptop) that is already connected to this network. The gateway for one device will be the gateway for all.
Why change DNS on TV?
Changing your DNS to a public one (e.g., 8.8.8.8 or 1.1.1.1) often solves the problem of Smart TV apps taking a long time to load or not opening at all, even though other websites work fine. This can also help bypass some ISP blocks.
Setup via WPS (Wi-Fi Protected Setup)
If your router supports WPS technology, you can connect Samsung UE40EH5307K Connect to the network without entering a password. This significantly simplifies the process and eliminates typing errors on the on-screen keyboard. Make sure WPS is enabled in your router's settings.
In the TV menu, go to Net -> Network settings and select the connection type WPSA message will appear on the screen indicating that the TV is waiting for a signal from the router. You have approximately 2 minutes to activate pairing mode on the router.
Click the button WPS On the router body. If there's no physical button, access the router's web interface using your computer's browser and find the WPS activation button there. The TV will automatically detect the signal, exchange encryption keys, and establish a connection.
This method is especially convenient if you have a complex password containing special characters that are difficult to find on the remote control. However, it's important to remember that WPS is considered a less secure protocol than WPA2/WPA3, so it's recommended to disable this feature on your router after setup if you don't use it regularly.
- 🔘 Find the WPS button on the back or bottom of the router.
- ⏱️ Please press the button within 2 minutes of starting the search on TV.
- 🔒 Use this method only on a trusted home network.
- 🔄 If the connection is not established on the first try, repeat the procedure.
Using an external USB Wi-Fi adapter
Model UE40EH5307K This model belongs to a series where the built-in Wi-Fi module was optional or unavailable in some regional versions. If the "Wireless Network" option is missing from the TV menu or is disabled, you'll need an external adapter. Samsung TVs from this era were picky about hardware compatibility.
The officially supported device is the adapter WIS12ABGNXUsing other models, even with similar specifications, may not work, as the TV firmware lacks the necessary drivers. The adapter must be inserted into the USB port marked with the logo. Wi-Fi or 1A (power supply 1 Amp).
After connecting the adapter, the TV should beep or display a notification that a new device has been connected. Restart the TV by turning it off using the power button on the TV (not just putting it in standby), and then turning it on again. A wireless connection option should appear in the network settings menu.
Diagnostics and solution
Even with proper setup, problems may still occur. If your TV displays "Unable to connect to the network" or "IP address not obtained," try resetting your network settings. In the network menu, find the item Network reset (Network Reset) and confirm the action. This will return all settings to factory defaults.
A common problem is when the router's DHCP table becomes full, stopping it from issuing addresses to new devices. A full reboot of the router can help: unplug it for 10-15 seconds, then plug it back in and wait for it to load. Then try connecting again on your TV.
It's also worth checking the date and time on your TV. If the system time is off (for example, set to the year 2000), website security certificates won't be verified, and the internet won't work. Set the current date in the section System -> Time.
⚠️ Note: The menu interface and item names may vary slightly depending on the firmware version. If you can't find the item you're looking for, search for a similar one or update your TV's firmware via a USB drive.
Why doesn't the TV see my Wi-Fi router?
Most likely, your router operates on the 5 GHz frequency, but your TV only supports 2.4 GHz. Go to your router settings and enable 2.4 GHz. Also, check if the network name is hidden (SSID Hide).
How to check internet speed on TV?
In the network settings menu, select "Network Status" or "Network Test." The TV will check the connection and display the current speed. For more accurate testing, you can install the Speedtest app from the app store, if your model supports it.
