Do you need Wireless Rounter for your home?

The benifit of using router is not only expand the number of sharing network or internet using. There is some protection between your computers and your broadband for protection. Here's why you need one for safety, plus all the other benefits a router provides.


First, Networking all devices.

The reason to have a router that you have computers, devices and multiple peripherals. The router is the center of interchange communication. The wireless router can handle not only Internet traffic but it has Ethernet switch and an access point(AP) for wireless. The AP is the part that handles all the Wireless LAN (Wi-Fi) traffic and watch for security. A wireless router is muti functions in one device. In non broadband situation, the AP can still get every device on the network communication.


Second, Using as Internet Splitter.

First and foremost, you have multiple devices. They all want—nay, NEED—Internet connectivity. The router is the "splitter" that makes that happens. By plugging the broadband into the WAN port, you can then get Internet out to all the other devices, both wired and wireless.


Third, PC safe guard.

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 is SPI or stateful packet inspection. Most modern routers have SPI, which keeps extra track of data in network packets and makes sure it's kosher (i.e., you requested it), protecting both the router and your computers by filtering out the bad. Note that these are not a replacement for software firewalls on your PC—every computer should have one running. Windows comes with a weak firewall built in, but you can always get a freebie from Comodo.
Other security you get from a router is: limiting a network to just computers you trust with MAC address filtering, secure wireless transmission, parental controls, web site filters, and more.


Forth, Roaming with Wireless

Modern Wi-Fi is the brand name for a technology called 802.11, which comes in many flavors, all with different speeds and ranges. Buy 802.11n products, especially if they're dual-band, and you'll be covered. They're slightly more expensive, but you get what you pay for. In this case, you'll have speed almost as good as a wired network, with extended range. Even the performance is improved in spots where signals used to get hung up. All that means is: you can move around and stay connected, even in your own home or office.


The last, Sharing Connectivity

It's very useful to share with friends. 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 use the Web and e-mail, but can't see your stuff. Small retail establishments can use this to be a free hotspot for customers. Offices can use it for visitors in for meetings.
