Samsung TV Not Detecting Wi-Fi? – Here’s How to Fix

Is your Samsung TV not detecting WiFi? The issue is very weird, and you will be left wondering what’s going on since you can’t stream your favorite shows. Fortunately, we’ve got plenty of detailed solutions.

A Samsung TV unable to detect Wi-Fi might not be at fault, but rather the Wi-Fi is overcrowded, the frequency is wrong, or the router is too far away. Alternatively, the network settings on the Samsung TV are all wrong or need to be reset.

The guide below will help you identify which situation applies and what you must do to fix the issue.

That way, you don’t have to return the TV to the manufacturer or buy a new one. 

Samsung TV Not Detecting Wi-Fi – Reasons

Is your Samsung Smart TV not detecting Wi-Fi? Such an occurrence is very odd and will make you wonder what is wrong with the TV or the router.

Fortunately, the issue is well known, and you can easily guess the causes.

Here are some of the most common reasons:

✅ The Router is Too Far

Even though Wi-Fi nowadays has a great range, it is still possible that you have positioned the TV too far from your main router.

✅ Overcrowded Channel

Wi-Fi frequencies operate within channels. If too many routers are nearby using the same channel, that will interfere.

✅ Wrong Frequency

If your router doesn’t have a dual-band, it may transmit in a frequency that the TV doesn’t pick up.

✅ Firmware Issue

The issue might stem from the TV itself, so you must manage its firmware/software.

Fix The Samsung TV Wi-Fi Detection

There are many solutions you can apply when the Samsung TV not detecting any Wi-Fi problem arises.

The issue is indeed odd, and then you will find yourself dealing with many settings, both on your router and the TV.

Get prepared to deal with technical terms!

1. Check The Distance

If your router is in the same room as the TV, you can skip this solution. On the other hand, if the router is in another room, you might want to check how strong the router’s signal is.

Do the following:

1. Download Wi-Fi Analyzer on your phone;
2. Open it;
3. Go to the room where the TV is located;

The app will tell you if the signal is strong or weak. If it is too weak, then you have the answer.

Even if your phone picks up the signal, it might be too weak for the TV because it consumes a lot of data!

Then do one of the following:

• Reinstall the router in another place on the house, closer to the TV;
• Buy a signal repeater and place it inside the router’s range but close to the TV’s range.

2. Change The Wi-Fi Frequency

Routers nowadays can operate in two frequencies: 2.4GHz and 5GHz. 2.4GHz has a wider range, but 5GHz is much faster.

Samsung TVs, from 2019 onwards, are capable of connecting to 5GHz networks.

In that case, you must check the following:

• Which frequency is your router operating in?
• Is it capable of dual-band?
• Which year was your TV released?

After checking that info, you must act accordingly:

• If the TV is from 2019 or newer, get a dual-band router or a single-band router that transmits 5GHz;
• If the TV is older than 2019, you need a router that can transmit 2.4GHz;

Note: If you've had a router for many years and didn't update it, odds are it still only transmits 2.4GHz. In that case, it doesn't deliver the best speed for your devices and is not compatible with some of them.

3. Inspect The Wi-Fi Channel

The TV is still not detecting Wi-Fi because the channel is overcrowded. All routers have access to the same channels, and if too many routers in the same building are on the same channel, interference will happen.

So do the following:

1. Install NetSpot software into your MacBook or Windows PC;
2. Open the software;
3. Scan the area to learn about the channels being used;
4. Take note of which channels are most used nearby.

How To Change The Channel

Next, you will have to open the router’s settings to change the channel at use:

1. Open your web browser;
2. Type your router’s IP;
3. Find the “Wireless settings”;
4. Click on “Channels” for the frequency that is getting interference;
5. Select a channel that is less used by your neighbors or not used at all.

Note: 5GHz has over 20 channels available, so it is less likely to get interference. 2.4GHz has only 11 channels available.

4. Try Reducing The Connected Devices

When the Samsung TV is not detecting or not connecting to the router, too many devices may be causing the router to overcrowd.

To test that hypothesis, we recommend you do the following:

1. Disable the Wi-Fi on some devices;
2. Turn the router off;
3. Wait a minute;
4. Turn the router on again;
5. Turn the TV on.

Even though later you will have to reconnect other devices again, at least your TV now has priority over the Wi-Fi network.

• That means enough data is allocated to it to connect and stream your favorite shows.

Tip: You also might need to get a new router if you notice that the one you have doesn’t work well when too many devices are connected.

5. Delete The Network

An even more odd occurrence might be the following: the TV has already been connected to the Wi-Fi in the past, but now it is not connecting.

However, the Wi-Fi credentials are still saved on the TV. In that case, you will do the following:

1. Open the TV’s settings;
2. Go to “General”;
3. Choose “Network”;
4. Select “Open network settings”;
5. On network type, select “Wireless”;
6. Choose “Manage Saved Networks”;
7. Select the network and click “Delete.”

Add The Network Again

You will have to add the network to the TV again.

But to ensure that the TV can recognize it, there are some additional steps:

1. Turn the router off;
2. Turn the TV off;
3. Turn them back on;
4. Go to “General”;
5. Choose “Network”;
6. Select “Open network settings”;
7. Select “Wireless”;
8. Choose “Add network.”

Solution #6: Reset Network Settings

Some Samsung TVs have the option of resetting the network settings. That feature is useful when the network capabilities refuse to work completely.

Here is how you can access it:

1. Open the TV’s settings;
2. Go to “General”;
3. Choose “Network”;
4. Find the “Reset Network” option;
5. When prompted, click on “Yes”;
6. After the process completes, turn the TV off;
7. Wait a bit and turn the TV on again.

Now your TV must be able to detect your Wi-Fi network.

Solution #7: Adjust the DNS Settings

The DNS is a very important configuration that allows devices to connect to the router seamlessly.

When the DNS is not set right, the Wi-Fi might not be detected, or the TV detects but can’t connect to it.

So here is what you will do:

1. Open the TV’s settings;
2. Go to “General”;
3. Choose “Network”;
4. Select “Network Settings”;
5. Find the “IP Settings”;
6. Choose “DNS Mode”;
7. Ensure that DNS is manual;

The point of entering this menu is changing the DNS port. You will probably see a 4-digit number. Next, you must change to one of the following: 8888 or 8844.

Change The IP Settings

Another useful change you might want to check while you are on the IP Settings menu is how your TV obtains IP info.

If the IP Settings is set to “Obtain manually,” click on it and switch to “Obtain automatically.” If it is already set to “Obtain automatically,” leave it that way.
