Laptop connected to wireless network where to lose pin

Friends installed a new wireless router, connect desktop computer, the Internet is normal. However, when using a laptop wireless connection, prompted to enter a PIN, not the pin where?

Answer:

Yes, when a laptop connects to a wireless network for the first time, it usually lets you enter a PIN code. It lets you enter the PIN code, which is the pin on the wireless router, not the pin for the notebook.

The pin is on the Back tab of the wireless router (pictured below), and a string of digits behind the PIN is the PIN code.

Each router has a different pin, remember the pin of your wireless router. The first time a laptop connects to a successful wireless router, the next time you open the notebook, it automatically connects to the wireless network without having to enter the PIN and wireless password.
