Before you get started Check your Internet connection If you don't have a good internet connection, the router setup experience will be frustrating. The simplest method is to connect a computer to the modem or gateway device supplied by your Internet service provider ISP. If your computer detects an Internet connection, you're ready to set up the router. Gather documentation Here's another "seems obvious" step—but one that will save you aggravation when you're in the middle of setup. Keep an eye out for stickers or slips of paper that might include important setup information, like the router's default username and password. Check for an app Many router manufacturers provide mobile apps or web dashboard that can be used for both setup and management. With a smartphone app, you may not have to connect the router to a computer to configure it. Check the documentation that came with your router to see if an app is available. Install and extend antennas If the router has antennas and they're separate from the router box, you'll need to install them. In addition, you should extend the antennas before beginning the setup process. Videos Router setup steps Step 1 Decide where to place the router The best place for a wireless business router is in an open area of the workplace, as you'll benefit from even coverage. However, sometimes it's not easy to find a space out in the open because you must connect the router to a broadband gateway from your ISP Internet service provider, which is usually attached to a cable near an outside wall. Step 2 Connect to the Internet Attach 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 ISP gateway's Ethernet port. Another option is to run Ethernet cables through the walls of your office to the chosen central location for the router. Yet another option is to install a mesh network with a router. A mesh network allows you to place multiple Wi-Fi transmitters across your home or office, all on one network. Unlike extenders, which can be used with any wireless router, mesh networks require a router with this capability built-in. No matter which option you choose, you'll use a basic Ethernet cable, plugged into the router's wide-area network WAN or Internet port. The Internet port is typically set apart from other ports by a different color. Check the router's LED lights Your router's LED lights tell you if you've successfully made an active Internet connection. If you don't see lights confirming such a connection, make sure you've plugged the cable into the correct port. Test the connection with a device Confirm 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 begin a wired connection, just as you did when confirming an active Internet connection. Step 3 Configure the wireless router gateway In some cases, ISPs offer customers gateways with built-in routers. In most cases, these combined devices are not built for business environments, nor do they have extra ports, security, and other options that allow you to add services and expand networks as the business grows. If you have a gateway with an integrated router, you'll have to configure the gateway to disable the router and pass the WAN IP address—the unique Internet protocol address that the Internet provider assigns to your account—and all network traffic through to your new router. If you don’t take this step, you may run into conflicts that prevent devices from working properly. You may need to contact your ISP for help with this step. Step 4 Connect gateway to router First, turn off the gateway. If there is already an Ethernet cable plugged into the gateway's local-area network LAN port, unplug the cable and plug it into your router's WAN port. Turn the gateway back on and wait a few minutes for it to boot up. Plug in the router's power supply and turn it on, again waiting a few minutes. Step 5 Use app or web dashboard The easiest way to continue with router setup is to use a mobile app if the router maker provided one. If there is no app, or you'd rather use the router's web-based dashboard, connect the router to a computer via an Ethernet cable. You might find the router's IP address printed on the back of device itself; if not, type a common router address, into the browser search bar. Step 6 Create a username and password To configure the router, you'll need to log in, using its default admin name and password. You can usually find this information printed on the router itself, or in an accompanying user manual. Next, enter the required credentials. Once you're 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 make sure to change them at the first opportunity. Step 7 Update the router's firmware Your router may need an update of the "firmware," or software that operates it. Update it as soon as possible, since the new firmware might fix bugs or offer new security protections. Some routers may download new firmware automatically, but many do not. You may need to check for updates through the app or the browser interface. Step 8 Create a Wi-Fi password Just as most routers come with preassigned admin usernames and passwords, most also come with preset Wi-Fi usernames and passwords. You’ll likely be prompted to change the Wi-Fi username and password, but even if you don't see such a prompt, plan to do so quickly. Step 9 Use auto-configuration tools where possible If your router is equipped with auto-install features, rely on them to help complete setup. For example, you should be able to use auto-configuration to manage IP addresses with the Dynamic Host Configuration Protocol DHCP, which automatically assigns IP addresses to devices. You can always change these addresses later. Step 10 Set up security Many router manufactures provide security functionality to safeguard network and user privacy. You can login into the web dashboard and enabling added security features such as firewall, web filtering, and access controls to protect yourself from malicious traffic. You can also set up virtual private networks VPNs for privacy. Shop for routers You’ve graduated from setting up that new wireless router and are ready for your next adventure setting up a firewall. Gulp. We know, seems really intimidating. But breathe easy, because we’ve broken it down to 6 simple steps that should help you on your way to network-security nirvana. And off we go… Step 2 Architect firewall zones and IP addresses No heavy lifting required. To best protect your network’s assets, you should first identify them. Plan out a structure where assets are grouped based on business and application need similar sensitivity level and function, and combined into networks or zones. Don’t take the easy way out and make it all one flat network. Easy for you is easy for attackers! All your servers that provide web-based services email, VPN should be organized into a dedicated zone that limits inbound traffic from the internet—often called a demilitarized zone, or DMZ. Alternatively, servers that are not accessed directly from the internet should be placed in internal server zones. These zones usually include database servers, workstations, and any point of sale POS or voice over internet protocol VoIP devices. If you are using IP version 4, internal IP addresses should be used for all your internal networks. Network address translation NAT must be configured to allow internal devices to communicate on the internet when necessary. After you have designed your network zone structure and established the corresponding IP address scheme, you are ready to create your firewall zones and assign them to your firewall interfaces or sub-interfaces. As you build out your network infrastructure, switches that support virtual LANs VLANs should be used to maintain level-2 separation between the networks. Step 3 Configure access control lists It’s your party, invite who you want. Once network zones are established and assigned to interfaces, you will start with creating firewall rules called access control lists, or ACLs. ACLs determine which traffic needs permission to flow into and out of each zone. ACLs are the building blocks of who can talk to what and block the rest. Applied to each firewall interface or sub-interface, your ACLs should be made specific as possible to the exact source and/or destination IP addresses and port numbers whenever possible. To filter out unapproved traffic, create a “deny all” rule at the end of every ACL. Next, apply both inbound and outbound ACLs to each interface. If possible, disable your firewall administration interfaces from public access. Remember, be as detailed as possible in this phase; not only test out that your applications are working as intended, but also make sure to test out what should not be allowed. Make sure to look into the firewalls ability to control next generation level flows; can it block traffic based on web categories? Can you turn on advanced scanning of files? Does it contain some level of IPS functionality. You paid for these advanced features, so don’t forget to take those "next steps" Step 4 Configure your other firewall services and logging Your non-vinyl record collection. If desired, enable your firewall to act as a dynamic host configuration protocol DHCP server, network time protocol NTP server, intrusion prevention system IPS, etc. Disable any services you don’t intend to use. To fulfill PCI DSS Payment Card Industry Data Security Standard requirements, configure your firewall to report to your logging server, and make sure that enough detail is included to satisfy requirement through of the PCI DSS. Step 5 Test your firewall configuration Don’t worry, it’s an open-book test. First, verify that your firewall is blocking traffic that should be blocked according to your ACL configurations. This should include both vulnerability scanning and penetration testing. Be sure to keep a secure backup of your firewall configuration in case of any failures. If everything checks out, your firewall is ready for production. TEST TEST TEST the process of reverting back to a configuration. Before making any changes, document and test your recovering procedure. Step 6 Firewall management All fires need stoking. Once your firewall is configured and running, you will need to maintain it so it functions optimally. Be sure to update firmware, monitor logs, perform vulnerability scans, and review your configuration rules every six months.
