4. Slow Internet Connection

If you experience the Discovery Plus app freezing or having other problems, it may be because of slow internet connection speeds while streaming high definition (HD) videos.

When streaming from Discovery Plus, if you want to stream 4K video, you will need a minimum download speed of 50+ Mbps. To stream HD video, you will need 5 Mbps.

There may be several reasons why the WiFi download speed is slow. Here are the most commonly encountered reasons and solutions for a slow Internet connection.

1. Weak Wi-Fi Signal to the Samsung TV

If the Wi-fi signal is weak between the TV and the wireless router, the internet connection may sometimes go down and lose its connection. Streaming issues may occur when using the Discovery Plus app.

Make sure the Wi-Fi signal from the TV to the wireless router is strong enough. If you want to check whether the Wi-Fi connection is strong enough, follow these steps.

On the Samsung TV remote, Press Home.
Select Settings.
Select General.
Select Network.
Select Open Network Settings.
Select Wireless.
In the list of wireless networks, see how many signal bars your wireless network has. 1 to 2 bars is the sign of a weak signal.

If the distance between your wireless network and your Samsung TV is too far, then you may experience poor connection quality and inconsistent Wi-Fi connections.

One other reason why weak Wi-fi signals might be present is because there could be obstacles between the TV and router, like many walls.

Moving the router closer to the TV will be easier for you to do than moving the TV closer toward the router for a stronger signal. If you want better Wi-Fi connections, place your router closer to your devices.

You’ll need to buy a wireless repeater if the router and Samsung TV cannot be moved. WiFi repeaters are also known as WiFi extenders.

The one below is one of the best ones out there and works well in smart homes. They can be found on Amazon:

2. Soft Reset the Wi-Fi Router

If your Wi-fi router hasn’t rebooted or been shut off for some time, there could be issues with its settings that can cause slower Internet speeds and interruptions.

Restarting and power cycling your network equipment, like your router or modem, can help if this is the case.

To soft reset your WiFi Router, follow these steps:

Unplug the Wi-Fi Router from the power outlet for at least 60 seconds.
Plug the Wi-Fi Router back in to the power outlet.
Turn On the Router if there’s an On/Off switch.
Wait a few minutes for the Router to start up and connect to your Internet Service Provider (ISP).

3. Try a Wired Connection

If your wireless connection is spotty and inconsistent, the router could be having trouble with its wireless signal.

Try using a wired connection to see if it’s the internet connection or the router that’s having issues. Wired connections are often more reliable than wireless ones, and easier to troubleshoot.

You can use a wired connection to test if you have a high-speed connection to your Samsung TV. Use an ethernet cable from the TV to the router to test the internet connection.

Follow these steps to connect and use a wired internet connection with your Samsung TV:

Plug an ethernet cable into one of the LAN ports on the back of the TV and connect it to the router.
On the Samsung TV remote control, Press Home.
Select Settings.
Select General.
Select Network.
Select OK for the TV to use the wired network to access the internet.

If you have an internet connection, the Wi-Fi router’s wireless ability might be having some difficulties. If none of these solutions work, then you might need to replace the router’s firmware, perform a factory reset, or replace the Wi‑Fi adapter.

4. Disconnect Other Devices from the Wi-Fi Network

When multiple devices connect to a single wireless router simultaneously, they may slow down overall network performance for everyone.

For example, when many smartphones, tablets and laptops are all connected to the same Wi-Fi network, each device’s internet speed will be very slow. That’s especially true if they’re all streaming HD videos on Discovery Plus or other streaming platforms.

Older Wi-Fi routers and modems tend to be particularly bad when it comes to dealing with multiple connected devices simultaneously.

If you want to improve your internet speed on your Samsung TV for Discovery Plus, disconnect all the other devices. Then reconnect Samsung TV to the Wi-Fi network again and see if you’re getting fast internet speeds again.

If this fixes the slow internet issue, you know that it was actually a problem with an old router not being able to support multiple devices. You should definitely consider upgrading to a new Wi-Fi router that supports multiple devices sharing the internet simultaneously.

5. Change DNS Server

Sometimes unstable internet connections can cause Discovery Plus issues on the Samsung TV The issues can be caused by incorrect DNS server settings from the ISP.

The Samsung smart TV will usually use the automatic DNS servers from the ISP, but you can change them to other DNS servers.

If you’re experiencing issues when trying to access Discovery Plus servers, you may be able to resolve these issues by switching from your ISP’s DNS servers to Google’s public DNS servers instead. Google’s DNS servers provide a more reliable internet connection than other options.

To manually change and use Google’s DNS servers on the Samsung TV, follow these steps:

On the Samsung TV remote control, Press Home.
Select Settings.
Select General.
Select Network.
Select Network Status.
Select IP Settings.
Select DNS Setting.
Select Enter Manually.
Select DNS Server.
Enter 8.8.8.8.
Try to open and reconnect to the Discovery Plus app again.

6. Reset Smart Hub on Samsung TV

Another app that you’re logged into on the Samsung Smart TV could be interfering with Discovery Plus and causing an issue.

If you reset the smart hub on your Samsung TV, it will you sign out of all the apps and may help resolve the problem. Before a smart hub resets, be sure you have access to all the login information, usernames and passwords for each device connected to the hub.

For newer Samsung Smart TV models made after 2020, follow these steps:

On the remote control, Press Home.
Select Settings.
Select Support.
Select Service Care.
Select Self Diagnosis.
Select Reset Smart Hub.

For older Samsung TV models made before 2020, follow these steps:

On the remote control, Press Home.
Select Settings.
Select Support.
Select Self Diagnosis.
