Working with a Cisco router and the Cisco Internet Operating System (IOS) is a great way to experiment with networking concepts and equipment and could have a positive impact on your career development. Learn the basic steps to configure a Cisco router to provide Internet access on a small network. Working with a Cisco router and the Cisco Internet Operating System (IOS) is a great way to experiment with networking concepts and equipment and could have a positive impact on your career development. You can get hands-on experience with IOS by installing a Cisco router at the edge of the Internet in your test lab at work or in your home office.

A Cisco router gives you more flexibility (with more granular controls than the Linksys or NETGEAR hardware commonly used in home offices) if you later want to add a Microsoft ISA Server firewall to the back end of your setup. If you don’t have a good internet connection, configuring the router will be frustrating. The easiest method is to connect a computer to the modem or gateway of your Internet Service Provider (ISP). When your computer detects an Internet connection, you can configure the router.

How to configure a Cisco router

Decide where to place the router

The best place for a corporate wireless router is in an open area of ​​the workplace because it will have uniform coverage. However, sometimes it is not easy to find an outdoor space as you have to connect the router to a broadband gateway from your ISP (Internet Service Provider), which is usually connected with a cable near an outdoor wall. .

Connect to the internet

Connect the router to a cable or choose a mesh router

To solve the “long distance” problem when connecting a router, you can use a CAT5e or CAT6 cable to connect the router to the Ethernet port of the ISP’s gateway. Another option is to run the Ethernet cables through the walls of your office to the central location chosen for the router.

Another option is to set up a mesh network with a router. A mesh network allows you to place multiple Wi-Fi transmitters in your home or office, all on one network. Unlike extension cords, which can be used with any wireless router, mesh networks require a router with this built-in capability.

Whichever option you choose, you will use a basic Ethernet cable, connected to the wide area network (WAN) or to the Internet port of the router. The Internet port is usually distinguished from other ports by a different color.

Check the router LEDs

The LED lights on your router let you know if you have successfully established an active Internet connection. If you don’t see any lights confirming this connection, make sure you’ve plugged the cable into the correct port.

Test the connection with a device

Verify that your router has a working connection by plugging a laptop computer into one of the device ports on the back of the router. If all goes well, you should be able to start a wired connection, just like you did when you confirmed an active internet connection.

Configure the wireless router gateway

In some cases, ISPs offer customers gateways with integrated routers. In most cases, these combo devices are not designed for commercial environments, nor do they have additional ports, security, and other options that allow you to add services and expand networks as you go. your business grows.

If you have a gateway with a built-in router, you will need to configure the gateway to turn off the router and forward the WAN IP address (the unique Internet Protocol address that the ISP assigns to your account) and all traffic. network to your new router. If you don’t follow this step, you may come across conflicts that prevent devices from working properly. You may need to contact your ISP for assistance with this step.

Connect the gateway to the router

First, turn off the gateway. If an Ethernet cable is already connected to the gateway’s local area network (LAN) port, unplug the cable and connect it to the WAN port on your router. Power up the gateway again and wait a few minutes for it to start. Connect the power to the router and turn it on, again waiting a few minutes.

Use the app or web panel

The easiest way to configure the router is to use a mobile app if the router manufacturer has provided one. If there is no application, or if you prefer to use the router’s web-based control panel, connect the router to a computer using an Ethernet cable.

You can find the router’s IP address printed on the back of the machine; otherwise, enter 192.168.1.1, a common router address, into the browser’s search bar.

Create a username and password

To configure the router, you will need to log in with your administrator name and default password. You can usually find this information printed on the router or in an accompanying user manual.

Then enter the required credentials. Once you are logged in, you should immediately create a new username and password. The defaults are usually something like ‘admin’ and ‘password1234’ which are obviously not secure, so be sure to change them at the first opportunity.

Update the router firmware

Your router may need to update its “firmware” or the software that operates it. Please update as soon as possible, as new firmware may fix bugs or provide new security protections.

Some routers can automatically download new firmware, but many don’t. You may need to check for updates through the app or browser interface.

Create a Wi-Fi password

Just as most routers come with pre-assigned administrator usernames and passwords, most also come with preset Wi-Fi usernames and passwords. You’ll likely be prompted to change your Wi-Fi username and password, but even if you don’t see this message, plan to do so soon.

Use automatic configuration tools whenever possible

If your router has automatic installation features, you can rely on them to complete the setup. For example, you should be able to use automatic configuration to manage IP addresses with Dynamic Host Configuration Protocol (DHCP), which automatically assigns IP addresses to devices. You can always change these addresses later.

Configure security

Many router manufacturers offer security features to protect the network and user privacy. You can log into the web panel and enable additional security features such as firewall, web filtering, and access controls to protect yourself from malicious traffic. You can also configure virtual private networks (VPNs) for privacy.
