What frequency does Rostelecom's Wi-Fi router operate on: 2.4 GHz vs. 5 GHz?

When it comes to home internet speed and stability, many Rostelecom users face the following question: What frequency does their Wi-Fi router operate on? — 2.4 GHz or 5 GHz? This determines not only the signal coverage in your apartment but also the actual connection speed on smartphones, laptops, and smart devices. In this article, we'll explore which frequencies Rostelecom routers support, how to determine them, and when to switch between bands for optimal performance.

Let us note right away: Rostelecom provides subscribers with various models of routers - from budget ones Sagemcom [Fast] 5364 to advanced Sercomm RV6699 with Wi-Fi 6 support. Most modern devices work in two ranges simultaneously (dual-band), but not all users know how to operate them. And some older models (for example, D-Link DIR-300) only support 2.4 GHz, and this critically impacts network performance.

Choosing a frequency isn't just a technical matter. It determines whether your 4K streaming will they be able to slow down on TV? smart speakers connect to the network, and why laptop The connection in the next room suddenly drops. Below, we'll cover all aspects in detail—from theory to practical setup instructions.

What are Wi-Fi frequencies: 2.4 GHz vs. 5 GHz?

A Wi-Fi signal is transmitted via radio frequencies, like any wireless connection. Today, two main frequency bands are used for home networks:

• 📡 2.4 GHz — the "good old" standard supported by all devices. It has a long range, but is susceptible to interference from microwaves, Bluetooth devices, and neighbors.
• 🚀 5 GHz — a more modern range with higher speed and less interference. However, the signal penetrates walls and ceilings less effectively.

The main difference is bandwidthAt 5 GHz, you can achieve speeds up to 1 Gbps (under ideal conditions), while 2.4 GHz rarely exceeds 300 MbpsBut this doesn't mean 5 GHz is always better: it all depends on your needs and home layout.

For example, if you live in apartment building If you have dozens of neighbors whose routers also broadcast on 2.4 GHz, your Wi-Fi will be clogged with interference. In this case, 5 GHz will be a lifesaver. But for dachas or large private house With thick walls, it's better to leave 2.4 GHz - it will provide coverage in all rooms.

What routers does Rostelecom offer: models and their frequencies

Rostelecom supplies its subscribers with routers from various manufacturers. Here are the current models (as of 2026) and their frequency support:

Important: If your router is older than 2018 (for example, D-Link DIR-300 or TP-Link TD-W8961N), it most likely does not support 5 GHz. In this case, to increase speed, you will have to either change the equipment or optimize the 2.4 GHz settings (which we will discuss below).

⚠️ Please note: Rostelecom periodically updates its equipment fleet. If your model is not listed in the table, check its specifications on the sticker on the back of the router or in personal account.

To find out the exact model of your router:

1. Turn the device over and locate the rating sticker.
2. Look at the line Model or Model.
3. If there is no sticker, go to the router's web interface (usually at the address 192.168.1.1 or 192.168.0.1) and check the section Status or System information.

How to find out what frequency your Wi-Fi is using

There are several ways to determine the current range:

Method 1: Through the router settings

The most reliable method is to go to the web interface:

1. Open your browser and type in the address bar 192.168.1.1 or 192.168.0.1.
2. Enter your login and password (usually admin/admin or indicated on the router sticker).
3. Go to the section Wi-Fi, Wireless network or Wireless.
4. View settings for 2.4GHz And 5GHz — if both sections are active, the router broadcasts in two ranges.

Method 2: Via a smartphone or laptop

On Android:

1. Open Settings → Wi-Fi.
2. Find your network in the list and tap its name.
3. Look at the line Frequency or Standard (For example, 802.11ac 5GHz).

On Windows:

1. Click Win + X and select Network connections.
2. Click on your network and select Properties.
3. In the section Protocol the frequency will be indicated (for example, 802.11n 2.4 GHz).

Method 3: By network name (SSID)

Many Rostelecom routers create two networks with different names by default:

• 🔄 RTK-WiFi_XXXX — usually 2.4 GHz.
• 🔄 RTK-WiFi_XXXX_5G — 5 GHz.

If you only have one network without a set-top box 5G, most likely the router only works at 2.4 GHz.

How to switch between 2.4 GHz and 5 GHz on a Rostelecom router

If your router supports both bands, you can manually select your preferred one. Here are the step-by-step instructions:

Disable important downloads (torrents, updates)

Remember your current Wi-Fi settings (network name, password)

Connect to your router via cable (recommended)

-->

Step 1: Login to your router settings

Open your browser and enter:

http://192.168.1.1

Or alternative address (if the first one doesn't work):

http://192.168.0.1

The login and password are usually located on a sticker on the router. If you've changed them and forgotten them, you'll have to reset the settings using the reset button. Reset (hold for 10 seconds).

Step 2: Setting up Wi-Fi

The interface depends on the router model, but the general logic is the same:

1. Go to the section Wi-Fi or Wireless network.
2. If there are tabs 2.4GHz And 5GHz, select the one you need.
3. To disable one of the ranges, uncheck the box Enable wireless broadcasting.
4. To change network name (recommended for convenience), find the field SSID and enter, for example, MyWiFi_5G.
5. Save the settings with the button Apply or Save.

Step 3: Connecting devices to the new band

After changing the settings:

• 📱 On your smartphone, forget the old network and connect to a new one (for example, MyWiFi_5G).
• 💻 On a laptop, you may need to restart the network adapter.
• 🎮 Game consoles (PS5, Xbox) and Smart TV also needs to be reconnected.

⚠️ Please note: Some devices (eg. Tuya smart sockets or old printers) only work on 2.4 GHz. If they stop connecting after disabling this range, turn it back on or create guest network at 2.4 GHz especially for them.

Which frequency should I choose: 2.4 GHz or 5 GHz?

There's no single answer—it all depends on your goals. Here are some recommendations:

Choose 2.4 GHz if:

• 🏠 You have a large apartment or house with thick walls.
• 📱 Connect old devices (for example, laptop 2012 or smart light bulb).
• 🌐 Stability is more important to you than speed (for example, for Zoom conferences).

Choose 5 GHz if:

• 🎮 Play online games (CS2, Fortnite) or watch 4K video.
• 🖥️ Work with large files over a local network.
• 📶 You have many neighbors with Wi-Fi in your home (less interference on 5 GHz).

The ideal option is - use both ranges simultaneously. Modern Rostelecom routers (for example, Sercomm RV6699) can automatically distribute devices by frequency depending on their capabilities. This is called Band Steering.

What is Band Steering?

This technology allows the router to "nudge" devices toward a more optimal frequency range. For example, if your smartphone supports 5 GHz, the router will automatically connect it there, leaving 2.4 GHz for older devices. It can be enabled in the Wi-Fi settings (section Smart Connect or Band Steering).

How to improve Wi-Fi signal on a selected frequency

If you've decided on a range but the signal is still weak, use these tips:

For 2.4 GHz:

• 🔄 Change the channel: In apartment buildings, channels 1, 6, and 11 are usually overloaded. Try channel 3 or 11 (in the router settings, section Wireless → Channel).
• 📶 Reduce the channel width: instead of 40 MHz select 20 MHz - this will reduce the speed, but increase stability.
• 🔋 Update the firmware router (section System Tools → Software Update).

For 5 GHz:

• 📡 Use channels 36-48 or 149-165 - they are less susceptible to interference.
• 🔌 Place the router closer to the center of the apartment — 5 GHz does not pass through walls well.
• 🛡️ Turn off energy saving on the laptop (in Device Manager → Network Adapters).

If nothing helps, consider buying Mesh systems (For example, TP-Link Deco) or Wi-Fi repeater (repeaters). Rostelecom sometimes rents them out—check with support.

Common problems and their solutions

Rostelecom users encounter typical errors when using Wi-Fi frequencies. Let's look at the most common ones:

Problem 1: The device does not see the 5 GHz network

Possible reasons:

• 📵 Your router does not support 5 GHz (check the model in the table above).
• 🔄 The 5 GHz band is disabled in the router settings.
• 📱 Your device is not compatible with 5 GHz (applicable to older smartphones and laptops).

Solution: Check your router settings and device specifications. If the issue is with the router, contact Rostelecom for a replacement with a 5 GHz model.

Problem 2: Low speed at 5 GHz

This may be due to:

• 📶 Weak signal (check the level in the device settings).
• 🔌 Overloaded channel (change the channel in the router settings).
• 🖥️ Restrictions from the provider (check the tariff in your personal account).

Solution: conduct speed test on the website Speedtest.net and compare the results on 2.4 GHz and 5 GHz. If the difference is significant, try changing the channel or placing the router closer to the device.

Problem 3: Constant disconnections at 2.4 GHz

The culprits:

• 🏢 Interference from neighbors (use a Wi-Fi analyzer to find a free channel).
• 🔌 Router or cable malfunction.
• 📡 Outdated firmware.

Solution: Update your firmware, change the channel to 1, 6, or 11, and if nothing helps, contact Rostelecom support for line diagnostics.

⚠️ Attention: If the Internet disappears completely after changing the frequency, check if the settings have been reset PPPoE (login/password for connecting to Rostelecom). Sometimes, changing Wi-Fi settings also resets network settings.

FAQ: Frequently asked questions about Rostelecom Wi-Fi frequencies

My Rostelecom router doesn't support 5 GHz. Can I get a replacement?

Yes, you can:

1. Contact Rostelecom support and request a replacement with a 5 GHz model (possibly for an additional fee).
2. Buy your own router (for example, TP-Link Archer C6) and connect it to the Rostelecom network in mode bridge.

Check the current replacement conditions in your personal account or by phone. 8 800 100 08 00.

How do I know which devices are connected to 2.4 GHz and which are connected to 5 GHz?

Go to the router's web interface (192.168.1.1) and find the section DHCP clients, Connected devices or Wireless ClientsIt will indicate which band each device is connected to. You can also use mobile apps like Fing.

Is it possible to use 2.4GHz and 5GHz at the same time?

Yes, if your router supports it. dual band (dual-band mode). In this case, it creates two separate networks, and you can connect devices to either one. Some routers (for example, Sercomm RV6699) can automatically distribute devices across ranges.

Why is the speed higher at 5 GHz, but the signal is weaker?

This is a physical limitation: the higher the frequency, the less effectively it penetrates obstacles (walls, furniture). 5 GHz works better within a single room, while 2.4 GHz covers a larger area but at a slower speed.

How do I reset my Rostelecom router if I forgot my password?

Press and hold the button Reset on the back of the router (usually 10-15 seconds) until the indicators blink. After this, the router will return to factory settings. The login and password for logging in will be indicated on a sticker (usually admin/admin or user/user).

⚠️ After the reset, you will need to reconfigure your internet connection (enter your Rostelecom login/password).
