The Windows firewall should be enabled by default.
Before doing anything to connect with the modem or router you can check the status of the firewall.
Get everything set up (monitor, keyboard, mouse, power cord) if a desktop.
Plug cords into the electrical outlets, boot up the computer.
Go to Control Panel and see if it is turned on. If not, turn it on.
If the system is a laptop, all you have to do is plug it in if the battery isn't charged.
After checking, you can connect to the modem, router, or network.
