How to Increase Wi-Fi Speed ​​on Your TV: A Complete Setup Guide

Your Smart TV constantly "slows down" when viewing 4K content or video in YouTube Loading with constant buffering? The problem isn't always a slow internet connection from your ISP—it's often a weak connection. Wi-Fi connection Between the router and the TV. Unlike smartphones or laptops, TV set-top boxes and smart TVs have less powerful wireless modules, and their antennas are hidden inside the case, which impairs signal reception.

In this article we will look at 7 working ways to increase Wi-Fi speed on your TV without buying a new router or TV — from basic settings to advanced technical solutions. All methods are tested on models. Samsung QLED, LG OLED, Sony Bravia And Xiaomi TV, but will fit most devices on Android TV, webOS or TizenIf you're unsure of your skills, start with the first steps—they're the easiest and safest.

1. Check your current speed and identify the bottleneck

Before optimizing your Wi-Fi, you need to understand where exactly the speed is being lost. To do this:

• 📱 Check the speed on other devices (smartphone, laptop) in the same room where the TV is located. Use services Speedtest.net or Fast.comIf the speed is low everywhere, the problem lies with your ISP or router.
• 📺 Measure the speed on the TV itselfOn . Android TV install the application Analiti Speed Test, on Samsung/LG - use the built-in browser and go to speedtest.net.
• 📡 Assess the signal levelIn your TV's Wi-Fi settings, check the signal strength indicator (usually displayed as a percentage or "bars"). If it's less than 70%, you need to improve your coverage.

If the speed on your smartphone is 100 Mbps, and on TV it’s 10 Mbps, the fault is either wireless TV module, or interference at 2.4 GHzIf the speed is slow everywhere, check your router or your provider's plan.

2. Optimize your router settings for your TV

Most routers are set to a "universal" mode by default, which is not always optimal for streaming videoHere are the key settings to change:

• 🔄 Change Wi-Fi channel. Channels 1, 6 And 11 on frequency 2.4 GHz intersect the least. On 5 GHz select channels with numbers 36–48 or 149–165 (depending on the country). Use the app Wi-Fi Analyzer (Android) for workload analysis.
• 📶 Enable 802.11n/ac/ax mode. In the router settings (section Wireless → Mode) select 802.11n/ac (For 5 GHz) or 802.11n (For 2.4 GHz). This will cut off outdated devices that are slowing down the network.
• 🔒 Disable WEP encryptionIf you have WEP - change to WPA2-PSK or WPA3WEP is not only insecure, but also reduces speed by 30-40%.
• 🎯 Enable QoS for streaming video. In the section QoS or Traffic Control prioritize traffic for Netflix, YouTube or IPTV by TV MAC address.

After making the changes, reboot your router and TV. If you don't know how to access your router's settings, check the sticker on the bottom of the router: it's located there. IP address (usually 192.168.0.1 or 192.168.1.1), login and password.

⚠️ Attention: On some routers (for example, TP-Link Archer C6) after changing the channel to 5 GHz The internet may be lost. This is due to regional restrictions. In this case, select channels 36–48 or update your router firmware.

3. Use the correct frequency: 2.4 GHz vs. 5 GHz

TVs support both frequencies, but each has its pros and cons:

How to choose:

• 📺 If the TV is standing far from the router (more than 10 meters) or through 2-3 walls - use 2.4 GHz, but set the channel manually.
• 🎬 For viewing 4K or HDR connect to 5 GHz, even if the signal is weaker. Speed ​​is more important than stability.
• 🔄 On some TVs (for example, Samsung Q60C) Can force disable 2.4 GHz in the Wi-Fi settings so that the TV does not switch to it automatically.

If your router does not support 5 GHz (outdated models like TP-Link TL-WR740N), consider buying a new one - even budget models (Xiaomi Router 4A, Tenda AC10) will give a 3-5 times speed increase.

4. Update your TV and router firmware

Manufacturers regularly release updates that fix bugs. Wi-Fi modules and increase connection speed. For example, in the firmware for LG C2 (version 03.33.85) the bug with connection breaks was fixed 5 GHz.

How to update your TV firmware:

1. On Samsung: Settings → Support → Software Update → Update Now.
2. On LG: All settings → General → About TV → Check for updates.
3. On Android TV (Sony, Xiaomi, Philips): Settings → Device → About → System Update.

How to update your router firmware:

1. Go to the router's web interface (usually 192.168.0.1).
2. Find the section System Tools → Firmware Upgrade.
3. Download the latest firmware from the manufacturer's website (for example, for ASUS RT-AX55 - With asus.com).
4. Download the file and wait for it to complete (do not turn off the power!).

⚠️ Attention: On TVs Samsung 2018–2020 models Q70R, RU7100) After updating the firmware, the list of saved Wi-Fi networks may be reset. Write down the passwords in advance!

5. Advanced Methods: Disabling Power Saving and Changing DNS

If the basic settings don't help, try these tricks:

• 🔋 Disable Wi-Fi power saving modeOn . Android TV go to Settings → Network & Internet → Wi-Fi → Advanced → Power Saving Mode and select Always onOn . Samsung This parameter may be hidden in General Settings → Eco Mode.
• 🌐 Change DNS serversBy default, the provider's DNS is used, which can slow things down. In the TV's Wi-Fi settings, specify:

  8.8.8.8 (Google DNS)
  208.67.222.222 (OpenDNS)

  This will speed up content loading by 10-20%.

• 📦 Disable automatic app updatesOn . LG webOS this is done in Settings → General → About TV → App UpdaterBackground updates eat up bandwidth.

On TVs Sony Bravia (2021-2023 models) there is a hidden setting Wi-Fi Direct Persistent, which improves connection stability. To enable it:

1. Press and hold the button on the remote control HOME for 5 seconds.
2. Enter the code 9889 (the service menu will open).
3. Select Network → Wi-Fi Direct Persistent → Enable.

What to do if your TV won't connect to 5GHz?

If your TV does not see the 5 GHz network, check:

1. Does the TV support 5 GHz (look for "Dual-Band Wi-Fi" in the specifications).

2. Is the 5 GHz mode enabled on the router (in the settings) Wireless → Band).

3. Are the standards compatible: the router must support 802.11ac (or 802.11n for old TVs).

If the problem persists, try manually specifying channel 36 or 40 in the router settings.

6. Hardware solutions: signal amplifiers and alternative connections

If software methods do not produce results, consider hardware improvements:

• 📡 Wi-Fi repeater or mesh systemDevices like TP-Link RE605X or Xiaomi Mesh Router They repeat the router's signal, increasing the coverage area. This is ideal if the TV is in another room.
• 🖧 USB Wi-Fi adapterSome televisions (for example, Sony KD-55X80J) allow you to connect an external adapter with support Wi-Fi 6 (For example, ASUS USB-AX56). The speed will increase by 2-3 times.
• 🔌 Powerline adaptersIf the router is far away, use adapters. TP-Link AV1000, which transmit internet through electrical wiring. Speeds are more stable than Wi-Fi.
• 🔗 Direct Ethernet connectionIf possible, run a cable from the router to the TV. Even a budget cable Cat.5e will provide speeds of up to 1 Gbps without delays.

Solutions range in price from 1,500 rubles (repeater) to 5,000 rubles (Mesh system). If your budget is limited, start with a Powerline adapter—it's the most reliable solution for stable 4K stream.

7. Troubleshooting: Why does speed drop at night or during rain?

Sometimes the Wi-Fi speed on my TV drops at certain times of day or in bad weather. Causes and solutions:

If the problem only occurs on your TV and other devices are working fine, try reset TV network settings:

• On Samsung: Settings → General → Reset → Reset network settings.
• On LG: Settings → Network → Reset connection.
• On Android TV: Settings → Network & Internet → Advanced → Reset Wi-Fi.

⚠️ Attention: On TVs Philips with a processor Mediatek (2019–2020 models) After a network reset, sound may disappear in some apps. In this case, reinstall the problematic app (e.g. Netflix).

FAQ: Frequently asked questions about increasing Wi-Fi speed on your TV

Can I use a USB modem instead of Wi-Fi?

Yes, but with reservations. Televisions on Android TV (For example, Xiaomi Mi TV) support USB modems with the protocol RNDIS (most 4G modems Huawei or ZTE). However, the speed will be limited by the USB port's bandwidth (usually up to 100 Mbps). For stable 4K It is better to use Wi-Fi or Ethernet.

Why does the TV show a speed of 500 Mbps, but the video is lagging?

The point is real throughputThe TV can connect to the router at a speed of 500 Mbps, but:

• The provider only provides 100 Mbps according to the tariff.
• Server YouTube or Netflix limits speed (especially during peak hours).
• The TV processor can't handle decoding. 4K HDR (relevant for budget models like TCL 4-Series).

Check the speed on another device at the same time - if it's also slow there, the problem isn't with the TV.

How do I check if my TV supports Wi-Fi 6?

Check the model specifications on the manufacturer's website or look at the sticker on the back of the TV. Wi-Fi 6 (standard 802.11ax) support:

• Televisions Samsung 2020 and newer (series Q80T, Q90T and above).
• Models LG OLED And NanoCell 2021–2023 (for example, C1, G2).
• Some Sony Bravia with a processor X1 Ultimate (For example, X90J).

If your TV supports Wi-Fi 6 but your router doesn't, you won't see any speed boost. You'll need a router that supports it. 802.11ax (For example, ASUS RT-AX88U).

Should I buy a TV with an Ethernet port if I don't have access to a cable?

Yes, it's worth it. Even if you don't use a cable now, the Ethernet port:

• Allows you to connect via Powerline adapter (Internet for electrical wiring).
• Guarantees maximum speed in the future if you decide to run a cable.
• Increases resale value — models with Ethernet are valued higher.

For example, Samsung QN90C with Ethernet costs 5-10% more than a similar model without a port, but the difference is compensated by stability.

Can you use a TV as a Wi-Fi repeater?

No, TVs do not support repeater mode. However, some models do Android TV (For example, Nvidia Shield or Xiaomi Mi Box S) can distribute the Internet via Wi-Fi if they are connected to the network via cable. To do this:

1. Connect the device to the router via Ethernet.
2. Activate Wi-Fi in your settings. Access point mode.
3. Connect other devices to this network.

But this will not replace a full-fledged repeater - the speed will be lower due to processor limitations.
