Hello folks.

So, I've setup a print server in our office using Ubuntu 20.04 LTS and successfully setup CUPS to be available over the network to all devices.

But, every time I tried to connect the print server to our router, it keeps showing "Activation of network connection failed." error whether that be a wireless (using TP-LINK dongle) or using ethernet port.

Thank you for your help in advance.

EDIT: It's not dual-boot. I'm only using Ubuntu Linux.
EDIT: I have TL-WN725N and TL-WN723N Wireless Adapter (not used at the same time)
