What is the wifi password of home inns?

If it is an ordinary stupid router, there is no way. If it is a professional router, such as a Cisco router, you can press ctrl+break to enter rommon mode when restarting, with the following prompts:

Rommon & gt conference document 0x2 142

This applies to cisco routers over the 2600 series.

Restart the router

& gt (constituent verb) means "put in a state of ..."

# Configuration test

# copystarting-config running-config sets the password again at this time.

# Username ... Password ...

# Exit

#wr

# Trust

# Configuration Register 0x2 102

In this way, the password was cracked. Other manufacturers have different methods to crack routers. You can check their operation manuals.
