Mac can access the Internet normally but cannot ping all the devices in the local area network. What's the reason?

can ping the extranet
can ping the router 192.168.1.1

other devices that cannot ping the local area network.

other devices on the LAN cannot ping themselves.

the firewall has been turned off..

could it be caused by some software?

first you have to make sure that your network segment is 192.168.1.*
you can view your ip information using the ifconfig command.
