How to Improve Wi-Fi Signal on a Samsung TV: A Complete Guide (2026)

You are trying to watch a movie in 4K on your own Samsung Smart TV, but the video constantly freezes and the picture becomes pixelated? Or maybe the TV refuses to connect to Wi-Fi at all, even though your smartphone has no problem finding a network? Signal problems on TVs Samsung (especially for models of the series QLED, Crystal UHD or The Frame) is one of the most common user complaints. And it's not always the device itself: router settings, physical obstacles, and even outdated TV firmware can be to blame.

In this article we will look at 7 Working Ways to Boost Your Wi-Fi Signal on TV Samsung — from basic (rebooting the equipment) to advanced (configuring router channels and using mesh systems). You'll learn which TV menu settings affect connection stability, how to choose the optimal location for the router, and when additional equipment is essential. You'll also learn why even a new TV can "lose" the network and how to fix it without calling a technician.

Spoiler: In 80% of cases, the problem is solved for free — just change a couple of settings. Let's start with the simplest.

1. Check the basic settings: router and TV

Before buying signal boosters or installing cables, make sure the problem isn't rooted in something basic. Users often struggle with poor Wi-Fi for months without realizing what's to blame. reset settings after update or a banal network overload.

First, do the following reboot both devices:

• 🔄 Disconnect the router from power 30 seconds, then turn it back on. Wait until it boots up completely (the indicators should be steady).
• 📺 Turn off the TV Samsung button on the remote control (putting it into standby mode is not enough!). Wait 1 minute and turn it on again.
• 📶 On your TV, go to Settings → General → Network → Open network settings → Wi-Fi and select your network again. Enter the password.

If the signal has not improved after rebooting, check:

• 🔌 Are there other devices connected to the router?? If so, turn them off temporarily. TVs Samsung (especially models before 2022) are sensitive to network load. For example, simultaneously streaming video on a TV and downloading torrents on a PC can choke the signal.
• 📡 Router operating mode. Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1) and check if the mode is enabled 802.11n/ac/ax (and not outdated 802.11b/g).

⚠️ Attention: If your router supports dual frequency band (2.4 GHz and 5 GHz), try connecting the TV to the network 5 GHz — it's less busy, but has a shorter range. In the TV menu, select the network with the following _5G or 5GHz.

2. Optimize the location of your router and TV

Physical obstacles are the main enemies of stable Wi-Fi. Concrete walls, metal structures, even aquariums and mirrors can weaken the signal by 30–70%. If your Samsung QLED It's in one room and the router is in another, that could be the problem.

Posting rules:

• 📍 The router should be placed on a raised platform. (Shelf, cabinet) – not on the floor or in a closed drawer. Antennas (if external) should be positioned vertically or at a 45° angle.
• 🚫 Move the router further away from microwaves, cordless phones (operating at 2.4 GHz!) and other sources of interference.
• 📺 TV should not be placed close to thick walls or metal objects. The optimal distance to the router is no more than 10 meters without obstacles.

If it is not possible to move the router, try change its orientationFor example, if the antennas are facing the wall, turn them toward the TV. In some cases, even turning the router around helps. 90 degrees.

3. Set up the channel and bandwidth on the router

By default, most routers operate on automatic channel selection — and this is the worst solution for a stable connection. The problem is that neighboring networks can use the same channels, creating interference. This is especially true for apartment buildings, where there may be a single stairwell. 10–20 Wi-Fi networks.

How to set up a channel manually:

1. Log in to your router's web interface (logins and passwords are usually located on a sticker on the back of the device).
2. Find the section Wireless (or Wireless network, Wi-Fi).
3. Select manual mode (Manual) and set the channel:
   • For 2.4 GHz optimal channels - 1, 6, 11 (they do not intersect).
   • For 5 GHz select channels 36–48 or 149–165 (less busy).

Save the settings and reboot the router.

Also check channel width (Channel Width):

• 📶 For 2.4 GHz install 20 MHz - this will reduce the speed, but increase stability.
• 🚀 For 5 GHz you can choose 40 MHz or 80 MHz (if the router supports 802.11ac/ax).

⚠️ AttentionRouter interface settings may vary depending on the model and firmware. If you can't find the settings you need, consult your device's manual or the manufacturer's support team.

4. Update your TV and router firmware

Over 40% of Wi-Fi issues on Samsung TVs are resolved with a firmware update. - this is especially true for models 2018–2021 (series NU7xxx, Q60T, TU8xxx). The manufacturer regularly releases patches to fix connection errors, but many users ignore the updates.

How to update your TV:

1. Go to Settings → Support → Software Update.
2. Select Update nowIf there is no update, click Checking for updates manually.
3. If the TV does not find updates via Wi-Fi, download the firmware from official Samsung website to a flash drive (format FAT32) and update manually via Settings → Support → Software Update → Update Now (USB).

Don't forget about your router! Outdated firmware can cause conflicts with modern devices. Update it via the web interface in the "Update" section. Administration or System tools.

Download the firmware from the official Samsung website

Format the flash drive to FAT32

Do not turn off the TV during the update

Check the software version after installation

5. Use additional equipment

If all the settings are optimized, but the signal is still weak, it's time to think about hardware solutionsHere's what really works:

• 📡 Wi-Fi repeater: Boosts the signal, but can reduce speed by 30-50%. Suitable for small apartments. Example: TP-Link RE605X (supports Wi-Fi 6).
• 🌐 Mesh system: Multiple access points create a single network without speed loss. Ideal for large homes. Examples: Google Nest Wi-Fi, ASUS ZenWiFi.
• 🔌 Powerline adapter: transmits internet through electrical wiring. Connect one adapter to the router, the second to the TV, and connect them with a cable. Ethernet. Example: TP-Link AV1000.
• 📶 External antenna for router: If your router has removable antennas, replace them with more powerful ones (for example, TP-Link TL-ANT2408CL with amplification 8 dBi).

For TVs Samsung with a connector Ethernet (For example, QN90C, S95C) the best option is direct cable connectionThis ensures maximum speed and stability, especially for 4K/8K content.

⚠️ Attention: When using a repeater or Mesh system, the network name (SSID) may change. Don't forget to connect your TV to the new network in the settings!

What to do if the TV does not see 5 GHz?

If your Samsung Smart TV 5GHz network is not detected, please check

1. Does your model support 5 GHz (the specifications should indicate this) Dual Band).

2. Is the 5 GHz mode enabled in the router settings (sometimes it is disabled by default).

3. Are the standards compatible: TVs Samsung may not be supported until 2017 Wi-Fi 6 (802.11ax).

6. Reset your TV's network settings

If the TV has previously connected to other networks (for example, while visiting someone or after moving), its network settings may have become clogged. This leads to connection conflicts. Factory reset network settings often helps to restore a stable connection.

How to reset settings:

1. Go to Settings → General → Network → Open network settings → Reset network.
2. Confirm the action. The TV will reboot.
3. After rebooting, reconnect to Wi-Fi by entering the password.

If resetting the network does not help, try full reset of the TV (all data and apps will be deleted!):

1. Go to Settings → Support → Self-diagnosis → Reset.
2. Enter your PIN (default) 0000 or 1234).
3. After the reset, set up your TV again as you did after purchasing it.

7. Check your power saving settings

Televisions Samsung (especially models with Eco Sensor) can automatically turn off Wi-Fi to save power. This causes connection interruptions while browsing. To disable this feature:

1. Go to Settings → General → Power Saving.
2. Disable options:
   • Automatic shutdown (Auto Power Off)
   • Eco mode (Eco Solution)
   • Energy consumption optimization (Power Saving Mode)

In the section Net turn it off Wi-Fi energy saving (if any).

Also check if the mode is turned on Quick start (Quick Start) - it may interfere with a stable connection. Disable it in Settings → General → Quick Start.
