If you don't remember your current Wi-Fi password or settings login information (admin/admin does not fit), there are two options:

Method 1: Reset the router to factory settings

Method 2: Password recovery through your provider (if the router is yours)

If the router was issued by the provider (for example, Rostelecom or Beeline), the remote control function may be enabled on it. In this case:

1. Call your provider's support team and tell them that you have forgotten your Wi-Fi password.
2. A specialist can reset the settings remotely or prompt you for the current password (if it is stored in their system).

2. Go to the section Guest Network (or Guest network in Russian-language firmware).
3. Activate the checkbox Enable Guest Network.
4. Configure the settings:
   • 🔤 SSID: guest network name (eg. Letai_Guest).
   • 🔒 Security: select WPA2-PSK.
   • 🔑 Password: Think of a simple but strong password (for example, Guest1234!).
   • ⏱ Schedule: Limit working hours (for example, from 8:00 to 23:00).

Benefits of a guest network:

• 🛡️ Guests will not see devices on your main network (computers, IP cameras, etc.).

⚠️ Attention: On some models Letai (For example, LT-300M) The guest network only operates on the 2.4 GHz frequency. If you have a dual-band router, check the 5 GHz settings separately.

7. Common mistakes and their solutions

When changing the password on routers Letai Users encounter typical problems. Let's look at the most common ones:

• 📱 Forget the network in Wi-Fi settings and reconnect.
• 🔧 Temporarily disable MAC address filtering (menu Wireless → MAC Filter).

Yes, if you access the control panel through a browser on your smartphone, open Chrome or Safari, enter 192.168.1.1 and log in. The interface is mobile-friendly, but for convenience, we recommend enabling "Full Site Version" in your browser settings.

How can I find out my current Wi-Fi password if it's saved on my laptop?

On Windows:

1. Open Network Settings → Network and Sharing Center.
2. Click on the name of your Wi-Fi network → Wireless network properties.

How many characters should a Letai password be?

The minimum length is 8 characters. The maximum depends on the encryption type:

• WPA2-PSK: up to 63 characters.
• WEP: 5 or 13 characters (but this type is not safe!).

We recommend using at least 12 characters with a combination of letters, numbers and symbols (Letai_2026!WiFi).

Why did the Wi-Fi section disappear after updating the firmware?

In new firmware versions for Letai The menu could be redesigned. Try:

1. Search section Advanced Settings or Network.
2. Use search by settings (if there is a field) Search at the top of the screen).
3. Reset the router to factory settings (if the interface has changed significantly).

If the section is still missing, check whether the router has been flashed to access point mode (AP Mode). In this case, Wi-Fi settings may be hidden.

Is it possible to set the same password for 2.4 GHz and 5 GHz?

Yes, but it's not recommended. Using the same password for both frequencies can cause devices to confuse networks, resulting in:

• 📉 Speed ​​drop (the device will be stuck on a congested 2.4 GHz network).
• 🔄 Frequent reconnections.

It's better to set different names (Letai_2G And Letai_5G) and passwords to manually select the optimal network.
