Wireless Firewall

Pros

Wireless routers are excellent for connecting notebook computers to the Internet and networks.

Using a wireless router requires you to use a wireless adapter in any computer that connects to it. Therefore, you may have to pay for extra equipment.
|

Not all wireless routers come equipped with a built-in firewall, so you may have to purchase one separately.
