Modern routers Rostelecom support dual-band operation, allowing you to connect to networks 2.4 GHz And 5 GHz (often referred to as 5G Wi-Fi). The latest band provides faster data transfer speeds, lower latency, and a stable connection—especially important for online gaming, video streaming, and 4K or video conferencing. However, many users experience difficulties when trying to connect their smartphone to the network. 5 GHz.
The problem often lies not with the phone itself, but with the router settings or standard incompatibility. In this article, we'll discuss how to properly configure your router. Rostelecom for operation in the range 5 GHz, check your smartphone's support for this range, and troubleshoot common connection issues. We'll pay special attention to router models. Sagemcom, Sercomm And Huawei, which are most often provided by the provider.
Checking if your smartphone supports 5G Wi-Fi
Before setting up your router, make sure your phone supports the range. 5 GHz. Most modern smartphones (released after 2018) are equipped with dual-band Wi-Fi modules, but there are exceptions - especially among budget models.
You can check support in several ways:
- 🔍 Device specifications: Find your phone model on the manufacturer's website (for example, Samsung Galaxy A52 or iPhone 12) and check the "Wireless Networks" section. Look for references to standards.
802.11acor802.11ax(Wi-Fi 5/6) - they operate in the range 5 GHz. - 📱 Wi-Fi settings: Open the list of available networks on your phone. If there are networks with the postfix
_5Gor5GHz, your device supports them. - 🛠️ Diagnostic applications: use utilities like WiFi Analyzer (Android) or Network Analyzer (iOS) to scan available ranges.
⚠️ Note: Some phones (e.g. older models) Xiaomi Redmi or Samsung J-series) may not support 5 GHz even if there is a Wi-Fi module. In this case, connecting to such a network is impossible - you will need to replace the device or use only 2.4 GHz.
If your smartphone supports 5 GHz, but it doesn't see the router's network. The problem lies in the router's settings. Let's move on to the next step.
Configuring a Rostelecom router to operate in the 5 GHz band
Routers Rostelecom by default, the network is often turned off 5 GHz or combine it with 2.4 GHz to one access point (function Smart Connect). To separate networks or enable 5 GHz, follow these steps:
- Login to the web interface:
- 🌐 Connect to the router via cable or Wi-Fi (even if it is a network 2.4 GHz).
- 🔗 Enter in the address bar of your browser
192.168.1.1or192.168.0.1(the address may differ - see the sticker on the router). - 🔐 Log in with your username

After changing the parameters, save the settings and reboot the router. Now the network 5 GHz should appear in the list of available ones on your phone.
Connecting your phone to a 5 GHz network
When the network 5 GHz Once configured on the router, all that's left is to connect your smartphone to it. The process is similar to connecting to a regular Wi-Fi network, but there are a few nuances:
- 📱 Open the Wi-Fi settings on your phone and find the network with the name you set for it 5 GHz (For example,
MyWiFi_5G). - 🔑 Enter the password (if it is different from the network) 2.4 GHz).
- 🔄 If the connection does not occur, forget the network (
DeleteorForget) and try again.
On Android (For example, Samsung, Xiaomi, Huawei) the path looks like this:
Settings → Wi-Fi → [Select 5G network] → Connect
On iPhone (iOS):
Settings → Wi-Fi → [Select network] → Enter password
⚠️ Please note: Some phones (especially iPhone older iPhone 6) can automatically connect to 2.4 GHz, even if 5 GHz available. To force the use of 5 GHz, turn off the network 2.4 GHz on the router or forget it in the phone settings.
If the connection fails, check:
- 🔄 Does the password match for 5 GHz (sometimes it differs from the password 2.4 GHz).
- 📡 Is the network down? 5 GHz in the router settings after rebooting.
- 📵 Check if your phone's power saving mode is enabled—it may limit the Wi-Fi module's performance.
Troubleshooting connection issues
If the phone does not see the network 5 GHz or it connects, but the internet doesn't work, use these instructions:
1. The network is not displayed in the list
- 🔌 Check if it is enabled 5 GHz on the router (see section above).
- 📶 Make sure your phone is within range - radius 5 GHz less than 2.4 GHz.
- 🔄 Restart your router and phone.
2. The connection drops or the speed is low
- 📊 Check your channel load using apps WiFi Analyzer or NetSpotIf necessary, change the channel in the router settings.
- 🔌 Disable the function on your router
Smart Connect(if it interferes with a stable connection to 5 GHz). - 📵 Make sure that any VPN or proxy is disabled on your phone—they may interfere with the connection.
3. Automatic switching to 2.4 GHz
- 📱 On Android disable the option
Auto-connectionorSmart Wi-Fi Switchingin the network settings. - 🍎 On iPhone Forget the network 2.4 GHzso that the device does not connect to it automatically.
What to do if the router does not support 5 GHz?
If your Rostelecom router is an old model (for example, D-Link DIR-300 or TP-Link TD-W8961N) and does not have a 5 GHz module, there are two options:
1. Upgrade your equipment - Contact Rostelecom to replace your router with a modern model (for example, Sagemcom Fast 5364).
2. Use an external Wi-Fi adapter - connect an additional access point with 5 GHz support (for example, TP-Link EAP225).
Checking connection speed and stability
After successfully connecting to 5 GHz Check if this improves speed. To do this:
- 📱 Connect your phone to the network 5 GHz.
- 🌐 Run a speed test on websites Speedtest.net or Yandex Internetometer.
- 📊 Compare results with connection to 2.4 GHz (to do this, temporarily connect to it).
Expected results:
- 📈 Speed: in the range 5 GHz should be 30–100% higher (depending on the router and phone).
- 📶 Latency (ping): should decrease from 30–50 ms to 10–20 ms.
- 🔄 Stability: no sudden drops in speed when moving around the room (within the operating radius).
⚠️ Attention: If the speed is 5 GHz lower than 2.4 GHz, check:
- Is the channel being used interfering (eg.
DFS-channels 50–144).- Is the router in the offline mode?
802.11ninstead of802.11ac.- Is the phone at the edge of the coverage area (in this case 2.4 GHz may be more stable).
For maximum performance, it is recommended:
- 📡 Place the router in the center of the apartment, away from walls and household appliances.
- 🔌 Use a cable
LANto connect stationary devices (TV, PC), freeing up Wi-Fi for mobile gadgets. - 📵 Disable the function on the router
WPS- it can reduce safety and speed.
5 GHz Network Security
Net 5 GHz Not only is it faster, but it's also safer—its shorter range makes it harder to intercept from the outside. However, this doesn't mean you can neglect security settings.
Recommendations:
- 🔐 Encryption: use
WPA3-PSK(orWPA2-PSK, IfWPA3not supported). Avoid outdatedWEPor open network. - 🔑 Password: Set a complex password (at least 12 characters with numbers, letters, and special characters). Example:
RtKm_7#pL9!vE. - 📡 Hiding SSID: disable the option
Hide network- it does not improve security, but it complicates the connection. - 🛡️ Guest network: If you have guests visiting you frequently, create a separate network with limited access to local devices.
On routers Rostelecom Security settings are usually located here:
Wi-Fi → Security Settings → Encryption Type
For additional protection:
- 🔄 Update your router firmware regularly (section
System → Software Update). - 📵 Disable remote router administration (option
Enable remote access). - 📊 Enable MAC address filtering if you want to restrict access to only your devices (although this is not a panacea for hacking).
