First of all, you need to confirm whether the used Yoyo bear has wifi function, then turn on the wifi function key, search for the wireless network you need to connect to, and enter the correct password before using it.

Tips: If you use Unicom broadband, the wifi connection cannot be used for the following reasons:

1, broadband is overdue or expired, and it needs to be paid or renewed in time.

2. The network cable is loose, so both ends of the network cable should be plugged tightly.

3. If the equipment is used for a long time, you can turn on and off the Internet devices such as optical cats and routers to restart.

4. If the above methods cannot be restored, it is recommended to contact the local customer service hotline staff.
