Ownership ADSL modem series H201L from the manufacturer Promsvyaz, which is often issued by the provider Byfly, requires an understanding of the basic principles of wireless signal management. Sometimes there is an urgent need to completely disable the radio module's radiation, leaving only the wired Ethernet connection active. This may be for security reasons, a desire to reduce electromagnetic radiation levels at night, or simply a need to redirect traffic exclusively to a desktop computer.
The procedure for disabling the wireless network on this device does not require any special technical knowledge, but it does have its own nuances associated with the features of the firmware and web interface. After applying the settings, the wireless network will no longer be visible to all devices, and Internet access will only be possible via cable. It is important to understand that changing the radio module configuration affects the fundamental operating parameters of the router, so all actions should be performed sequentially and deliberately.
In this guide, we'll detail every step required to properly manage the Wi-Fi function. We'll cover logging into the admin panel, navigating the settings menu, and switching antenna modes. We'll also cover security issues and common errors users encounter when navigating the interface. Promsvyaz.
Why disable wireless on a modem?
The main reason why users tend to deactivate the wireless data function is to increase the level cybersecurityWhen the radio module is turned off, attackers are physically unable to intercept the signal or attempt to brute-force your network password, as the access point ceases to exist in the air. This is especially important for devices used in offices or high-traffic areas, where the risk of unauthorized access is highest.
Another important aspect is energy saving and reducing the load on the router's processor. Although the radio module consumes little power, combined with neighbors constantly searching for networks and background processes, this creates additional thermal load. Disabling unused functions helps the device H201L operate more stably and cooler, which has a positive effect on the service life of electronic components.
There's also a category of users who experience discomfort from constant electromagnetic radiation, especially at night. Completely disabling Wi-Fi allows for a "digital detox" and reduces background noise in the bedroom. It's also an effective way to limit children's internet access on mobile devices, limiting internet access to the parent's computer via a cable.
⚠️ Important: Before making any changes, ensure you have physical access to the modem and an Ethernet cable. Disabling Wi-Fi will prevent you from managing the router wirelessly.
Preparing to configure the interface
Before making any configuration changes Promsvyaz H201L, you need to ensure a stable connection between your computer and the modem. The most reliable way is to use twisted pair (LAN cable). Connect one end of the cable to any of the ports LAN on the back of the modem, and the other into the network card of your laptop or PC. Make sure the indicators LAN on the device's body began to blink or glow continuously.
If a cable connection is unavailable, you can use your current Wi-Fi connection, but be aware of the risk: the connection will be lost when applying the settings. In this case, you'll have to reconnect to the network, which will be impossible without a cable after Wi-Fi is disabled. Therefore, wired connection is a prerequisite for comfortable and safe setup.
It's also worth checking your computer's network adapter settings. To properly use the modem's web interface, your computer must receive IP address Automatically. In most cases, the default setting in Windows or macOS is "Obtain an IP address automatically" (DHCP), and no further action is required.
☑️ Check before setup
Login to the Promsvyaz H201L web interface
The modem's settings are managed using a built-in web interface. Open any modern browser (Chrome, Firefox, Opera) and enter the device's default IP address in the address bar. For most modems Byfly And Promsvyaz this address is 192.168.1.1In some rare cases the address may differ, for example 192.168.0.1, so it is recommended to check the sticker on the bottom of the device, where the exact data is indicated.
After entering the address and pressing Enter, the system will ask for authorization. You will need to enter login And passwordFactory login information is usually also indicated on a sticker under the case. The standard pair for many models is the login admin and password admin or passwordIf you've previously changed this information and forgotten it, you'll need to perform a factory reset.
The management interface may look different depending on the firmware version installed by your provider. However, the menu layout remains the same. After successfully logging in, you'll see the main connection status page, which displays DSL speed, uptime, and the status of connected users.
| Parameter | Default value | Note |
|---|---|---|
| IP address | 192.168.1.1 | Main gateway |
| Login | admin | Superuser rights |
| Password | admin | It is recommended to change |
| Interface | Web UI | Access via browser |
⚠️ Note: Firmware interfaces may differ depending on the year of manufacture of the device and the software version from the Byfly provider. If the menu paths listed do not match, look for sections with similar names in English or Russian.
Find the wireless network section
After logging in, the control panel will open. Depending on your firmware version, the menu may be on the left, at the top, or in a tiled layout. We need to find the section responsible for wireless technologies. Look for the tabs with the following names: Wireless, Wi-Fi, WLAN or Wireless network.
In the classic interface Promsvyaz a structure where you need to go to a menu is often used Advanced Setup (Advanced settings), and then select the item WirelessWithin this section, you may need to select a subsection. Basic or SecurityThe main thing is to find the switch that turns the radio module on or off.
If the interface is customized by your provider, look for the "Wi-Fi Setup" or "Wireless Network" tabs. Some software versions require you to first select an interface (e.g., wlan0 or ra0) from the drop-down list before the settings become available. Be careful when selecting the interface to avoid changing the guest network settings instead of the main one.
What if the menu is in English?
You'll need basic words: Wireless, Enable, Disable, and SSID (Network Name). Use your browser's translator or refer to the antenna icons.
Disabling the Wi-Fi module: step-by-step instructions
Once in the wireless settings section, locate the setting that directly controls the module's status. It may be called Enable Wireless, Wireless Radio, Turn Wireless On/Off or simply have a checkbox labeled "Enable wireless networking." To disable Wi-Fi, uncheck the box or toggle the slider to the "On" position. Off / Disable.
In some firmware H201L the button with the name is used Wireless Off On the main status page or in the quick menu. Clicking this button instantly deactivates the signal. However, if you don't see this button, be sure to look for the checkbox deep within the menu. After unchecking the radio module activation box, the changes will not yet take effect.
The most important step is saving the configuration. Find the button Save (Save), Apply (Apply) or Save/ApplyPressing this button writes the new settings to the modem's non-volatile memory. The device may reboot or simply flash its indicators. At this point, the wireless network will disappear from the list of available connections.

Alternative methods and a physical button
Some models of modems Promsvyaz And Byfly are equipped with a physical button for quickly turning Wi-Fi on and off. It can be located on the front panel, on the side, or on the back, near the ports. It is usually marked with an antenna icon or the word WLANA short press of this button (about 1-2 seconds) often toggles the state of the wireless module without entering the web interface.
However, the functionality of the physical button depends on the specific hardware platform version. On some devices, it works out of the box, on others, it requires software activation, and on others, it may not perform any action at all, being reserved for future use. You can check the button's functionality by monitoring the Wi-Fi indicator on the device: if it goes out when pressed, the method is working.
There is also a method to disable it through WPS, although it is less reliable. In some configurations, holding the WPS button for longer (more than 5-7 seconds) can disconnect the wireless network, but more often this action resets the settings or initiates pairing mode. You shouldn't rely on this method unless you're sure about the specifics of your firmware.
⚠️ Caution: Holding the buttons on the device for longer than 10 seconds often results in a full factory reset. Be careful not to lose your PPPoE internet access settings.
Possible problems and their solutions
A common issue is that Wi-Fi doesn't turn off after saving the settings. This may occur because you changed the settings for the guest network instead of the main network, or because you didn't apply the changes. Some providers also block the ability to completely disable the radio module through the standard interface, imposing their own control scripts.
If you can't access the settings, check if your computer's IP address has changed. After attempting to configure the modem, you may need to manually enter a static IP address within the range 192.168.1.x with a mask 255.255.255.0to regain access to the device's web interface.
If you've "locked yourself out" by disabling Wi-Fi and not having a cable handy, a hard reset is the only solution. Find the hole Reset On the back panel, turn on the modem and use a thin object (like a paperclip) to press the button inside the hole for 10-15 seconds. The lights should flash, indicating a factory reset, with Wi-Fi re-enabled.
- 🔌 Check the integrity of the LAN cable and the tightness of the connection.
- 🌐 Make sure your computer's IP address is on the same subnet as your modem.
- 🔄 Try clearing your browser cache or using incognito mode.
- ⚙️ Make sure there is no proxy server installed in your browser.
How to reset the administrator password?
The only way is to physically reset the device. All passwords, including those changed by the user, will return to the factory defaults (admin/admin).
Frequently Asked Questions (FAQ)
Does turning off Wi-Fi affect wired internet speed?
In theory, disabling an unused radio module can slightly reduce the load on the router's processor, which in rare cases can stabilize ping. However, in practice, with modern ADSL modems, the difference in wired connection speed will be imperceptible to the user.
Is it possible to turn on Wi-Fi remotely if it is turned off?
No, if the wireless module is disabled programmatically through the settings, it stops receiving and transmitting signals. Remote activation is only possible if the device supports special control protocols over a wired network (LAN) or if there is physical access to the button on the device.
Is it safe to leave my modem with Wi-Fi turned off for long periods of time?
Yes, this is completely safe for the device. On the contrary, the absence of constant RF load can have a positive effect on the chip's temperature. The only thing to keep in mind is the need to regularly reboot the device to prevent freezing.
Will my neighbors connect if I just hide the network name (SSID)?
Hiding the SSID doesn't disable Wi-Fi; the signal continues to be transmitted. Experienced users can detect hidden networks with specialized scanners. To ensure no connection, you must disable the radio module (Disable Wireless), not simply hide the name.
