4 features you should know about your router

Some tips and tricks that you need to know about the router which can come handy in near future.

The increasing growth of mobile technology has made Wi-Fi ​​networks increasingly popular, everywhere we go it’s hard not to find at least one wireless network that guarantees access to the Internet, as we know this is possible thanks to wireless router.

Wireless routers are fairly simple devices at least in appearance, in simple words, are responsible for providing connectivity between devices in a network and in turn interconnect multiple networks and route packets traveling between them, assigning IP addresses and even providing security, among other things.

These small devices are designed and programmed in such a way as to be easy to use for anyone, even for those whose knowledge of networks are practically nil. Most of them only needs to follow the instructions of a few pages of the manual and connect a pair of wires to start working. But beyond its simplicity there are a number of configuration options that many overlook and can be useful and important in certain situations .To access these options must enter the router configuration interface . Access to these options varies from one brand to another and precise instructions are in the manual of the device and in some cases, on a label attached to the base unit. Usually just enter in the browser address bar type the IP address or and to authenticate the session using a combination of username: admin and password(this also varies by brand and model ).

Once we enter the interface configuration of our router we will find a variety of options, some quite basic and some a little more complex. Let’s concentrate on the latter.

MAC Filtering

Although some routers have security options to control the devices that connect to it, there is a much more effective way to allow / disallow these connections and it is filtering by MAC.

Absolutely all devices that have a wireless network card or not-have a code that uniquely identifies this code is known as MAC address. Now, with MAC filtering enabled, you can create a list of addresses of the devices you want to connect or not your router.

Although this method is a little safer, has its cons. For example, every time a friend comes home and want to connect to his mobile phone with your router, you must manually enter the MAC address of your computer to the filter list, making one simple process cumbersome.

Port Forwarding

Data traveling over the Internet do so in the form of packets, these packets are addressed to a specific IP address and port. Every application installed on your computer uses a port (or a range of ports) to communicate, for example, browsers use port 80 for the http protocol that allows servers to connect to websites and apply its contents.

The routers are smart enough to determine to which network device is aimed a particular package, but sometimes you need to manually configure the way that traffic to specific ports is handled and thus ensure that applications run properly , is the case of some games, programs to download torrents, among others.

Also useful when opening some ports have a server installed on our computer and we need a network outside our local client to access the Internet-this-from.


QoS stands for Quality of Service,a very important feature that bring the routers to prioritize media packets traveling through the router. As I said earlier, data travels in packets and each application generates a different type of packages.

When we have many applications using the connection, online gaming and multimedia performance are affected significantly because, among other things, an increase in latency.When you enable QoS, the router assigns higher priority to multimedia packages and trying to reduce the negative impact. The rest of the applications load slower, but can enjoy games and streaming without jumps or known lag .

Guest Access

Most of us have a router configured to require a password to each new device trying to connect. By using this method, any user who knows the password can not just connect and get internet access, but you can also access the list of connected to the router or in other words, you have full access to our local network devices This can pose a security risk if an attacker manages to take the password.

To reduce the risk of this type some routers have the option to grant guest access ( Guest Access ) to specific users and devices. This option allows guests devices only have access to the Internet connection, but can not go much further into the local network .


To these characteristics we can add some tips to improve the security and performance of our Wi-Fi network that we had shared earlier.It is also worth remembering that, if something goes wrong we can restore the router to its original state using the button to reset it usually by the connector cord from the router, or using the respective option in the same management interface of the device.
