### Telia X2 router specifics

 If you are using a Telia X2 (Technicolor DGA4330) router, you must adjust the router settings before connecting the device - deactivate the router's 2.4GHz network 802.11n standard, allowing only 802.11b/g connection:
**1. Connect your computer or smartphone to your home network (via cable or WiFi).**
**2.** Open a browser and go to **[192.168.1.1](tel:19216811)**.
**3. Log in**:
**• Username:** *user* (default)
****•**Password:** *Web Access Key* (printed on the bottom of the router)
**4. Open** **Advanced interface**.
**5.** From the menu, go to **Wireless**.
**6.** Click **Show advanced**.
**7.**Change the 2.4GHz WiFi mode to **802.11b/g** (disable 802.11n support).
**8. Save the changes.**

## Result

 Your device is successfully connected to your home WiFi network and ready to be linked with the Qilowatt app.
