1. Go to the section Network → WLAN → Security.
2. In the field WPA Pre-Shared Key Enter a new password.
3. In the drop-down menu Security Mode select WPA2-PSK (recommended) or WPA/WPA2-PSK (for compatibility with older devices).
4. Click Apply or Save.

For routers ZTE F680 And F670:

1. Open Network → WLAN → Basic.
2. In the field SSID You can change the network name (optional).
3. Go to the tab Security.
4. In the field Pre-Shared Key Please enter a new password.

FAQ: Answers to Frequently Asked Questions

Is it possible to change the Wi-Fi password using the My TTK app?

Yes, but not for all router models. In the app, go to "My Hardware" → select your router → "Wi-Fi Settings." If you don't see this option, use the web interface.

The application only works for routers linked to your personal account in TTKIf the router was purchased separately, this method will not work.

How can I find out which router issued TTK to me?

2. Log in to your personal account on the website ttk.ru, section "Equipment".
3. Call support by phone 8 800 250-0-250 and name the connection address.
