Before you begin, make sure your router is connected to power supply and at least one indicator is lit on it (for example, Power or 4GIf the indicators don't light, the problem may be with the power supply or the device itself, and turning on Wi-Fi won't help.

1. Enabling Wi-Fi via the Keenetic web interface

The most reliable way to activate a wireless network is to use web configurator router. You don't need to install any additional software; any device with a browser (computer, smartphone, tablet) is sufficient.

If you are connected to the router via cable, simply open your browser and enter in the address bar 192.168.1.1 or my.keenetic.netIf there is no Ethernet connection, temporarily connect to the router via mobile hotspot (if supported by your model) or use Wi-Fi Direct (if the function is activated).

Connect the router to power and wait for it to load|Connect the device to Keenetic via cable or temporary network|Open a browser (Chrome, Firefox, Edge) and clear the cache|Enter the address my.keenetic.net or 192.168.1.1-->

After logging into the control panel:

1. Enter your login and password (default - admin/admin, if you haven't changed it).

2. Go to the section Wi-Fi network (or Wireless network in old firmware).

3. Find the switch Turn on the hotspot and activate it.

4. Click Apply and wait for the settings to be saved (indicator Wi-Fi on the router should blink).

If section Wi-Fi network missing, check the firmware version in System → Updates. For Keenetic 4G II current version - KEENETIC-4G-II v3.9.10 or newer. Older firmware may not display all options.

2. Quickly enable Wi-Fi with the WPS button

If you don't have access to the web interface (for example, you forgot your password), you can try to activate Wi-Fi using WPS buttons on the router body. This method only works if the WPS function isn't disabled in the settings.

On Keenetic 4G II The WPS button is usually located on the rear panel and is marked with a corresponding icon (two arrows forming a circle). Here's how to do it:

2. Find the button WPS and press it once (don't hold back!).

3. Wait 1-2 minutes - indicator Wi-Fi should light up or start flashing.

4. Try connecting to the network from any device (the network name and password remain the same).

If the network does not appear after pressing WPS, check:

• 🔌 Router power supply — the power supply may be faulty.
• 📡 Antennas - they must be tightly twisted.
• 🔒 WPS settings — in the web interface in the section Wi-Fi Network → WPS The function must be enabled.

What to do if WPS doesn't work?

If the WPS button does not respond, it may mean:

1. Hardware failure — the button contacts are oxidized or damaged.

2. Software block — WPS support is disabled in the firmware (check in the settings).

3. Conflict with other functions — for example, if the "Guest Network" mode is activated at the same time.

In this case, turn on Wi-Fi via the web interface or reset the router to factory settings (button Reset for 10 seconds).
