LAN machine can't ping printer

JonathanLee

@eiger3970-0 Don't change that it should be 255.255.255.0 as your subnet with the cider notion of /24

@JonathanLee Hello, I changed the printe to:
IP address: 192.168.1.160
Netmask: 255.255.255.0
Gateway 192.168.1.170

Unfortunately, the computer won't ping the printer via the VM router?

Computer with Ethernet cable to printer.

@eiger3970-0 Just noticed the computer said Wired Lan cable was unplugged.
I barely touched the Ethernet cable at the back and the RJ45 NIC PCIe LED turned on and green.
I guess that's the LAN enp2s0 that changed from DOWN to UP.
Must be something wrong with the NIC, the NIC's insertion into the MOBO or the cable...nothing was touched before the problem.

Your gateway isn’t .1 ?

@JonathanLee This is solved, somehow, I don't remember...just noting the thread can be closed.
