Why we need Wireless Router
Tweet
In past when it was okay to plug your broadband modem directly into your computer. That was okay that time, but doing that todays is not possible to leaving your front door wide open for malicious jerks.
There should always be mediator between you and your broadband for protection. What was it, it is router.
1. Multipurpose Device
First and foremost, you have multiple devices. By plugging the broadband into WAN port, you can then get Internet out to all the other devices, both wired and wireless.
2. Networks for All
The ultimate reason to have a router: you have multiple computers, phones, and other device. It not possible to provide multiple peripherals(printer etc.). Sounds nice if they all talked to each other? The router is the heart of all that communication.
The modern “wireless router” does more than hand only Intenet traffic. It has a built in Ethernet switch (those are the Ethernet ports for the wired devices on the network) as well as an access point for wireless.
Even without broadband, the switch can still get every device on the network talking.
3. Provides PC Safety
Routers typically have two built in firewalls. The first is simple NAT for network address translation, which isn’t so much for protection as it is for simply making the Internet Connection work to all your computers. The Second one is SPI or stateful packet inspection. Most modern routers have SPI, which keeps extra track of data in network packets and makes it’s kosher, protectin both the router and your computers bby filetering out the bad.
Another advantage from a router is: limiting a network to just computers you trust with MAC address filtering, secure wireless transmission, website filters, and more.
4. Sharing is Caring
It’s nice to share your internet connections to share with friends and neighbors. The right router can let you do that with your own Internet connection. You effectively get two networks, one that’s just for you and one for guest access. That way outsiders can access your broadband connection, but can’t see your stuff.
5. It Gives You Wireless Freedom
Why be sticked to one place with your pc? You can move around and stay connected, without loss of speed.
