What is a wireless router?
First let’s see what a router is: is a networking device that manages Internet traffic, shares it between multiple connected computers, filters traffic, acts as a firewall, gateway, NAT server and wireless access point (if we talk about a wireless router). A router is essentially a collection of network cards and an intelligent switch that splits the incoming/outgoing traffic between those cards.
A wireless router is also more vulnerable than a wired one as it can be hacked from distance if a strong enough security protocol and/or MAC filtering table is used. Always consult your router’s manufacturer manual to see the best solution at your disposal to secure your personal network. Usually the best gaming routers in shops are also the best choice when it comes to wireless routers.
