![]() Now, we need to configure the wireless networks using more or less the same method:įigure 2 – This is how your screen will look while you configure your networks. Under Virtual Interfaces, click Add Virtual AP to create two other wireless networks (Guest and Work) and configure them in a similar fashion. Our next step is to set up the virtual networks for Fox – Guest and Fox – Work. The below image displays these steps (highlighted). Once this is successfully set up, save your settings and apply changes. As shown in the GIF below, we are changing all of the SSIDs to Fox – General. We want Fox – General to have both 2.4GHz and 5GHz capabilities. To kick things off, go to Wireless → Basic Settings in DD-WRT to change the name of the router.Īfter changing the name of the router, go to Wireless → Basic Settings in DD-WRT to set up your wireless networks. However, many devices are making the switch to 5GHz. You might need the 2.4/5GHz capabilities if some of your IoT devices still require 2.4GHz. If you need both 2.4GHz and 5GHz wireless bands, you’ll need to bridge the wireless networks together or use separate SSIDs for 2.4/5GHz. In this example, we will be building a network where Fox – General has both 2.4 and 5GHz capabilities however, the Fox – Guest and Fox – Work networks will be 5GHz specific. Closely follow the steps below to ensure your efforts are successful, and your home or small business network will become that much more secure. Now it’s time to actually segment our network. The General network will host any personal devices (e.g., Wi-Fi cameras and smart TVs), the Guest network will host visitors’ devices finally, the Work network will be a dedicated network for work-specific devices (e.g., work-sanctioned laptops).Įach of these networks will have a different IP subnet for organizational purposes. We’ll name these according to their intended use: Fox - General, Fox - Guest, and Fox - Work. NOTE: This is the most important part of the process! Make sure you’ve enumerated all of these requirements before you even begin.įigure 1 – A layout visualizing how our three networks will interact with our router and connect to the Internet.īased on our requirements in the example above, let’s create three wireless networks. And should you have a temporary visitor, you may want them to access a separate network away from your trusted devices. #Dd wrt v24 guest wifi Pc#For example, your PC will need to communicate with your smart printer, but you probably want your IoT devices on a separate network altogether. Identify each device and map out what access each device needs. To start, you’ll need to design your new network layout. ![]() (Some recommended alternatives to DD-WRT you might consider are OpenWrt or Gargoyle Firmware.) PART 1: PLANNING And while we will use DD-WRT in this example, the ideas and concepts presented here are applicable to other platforms. #Dd wrt v24 guest wifi how to#We won’t cover how to flash the router with DD-WRT, but follow flashing instructions carefully or you may end up with a bricked router. Not sure if your router supports DD-WRT? You can find out here. The default ASUS firmware is pretty capable itself, but we’ll use the DD-WRT firmware since the router supports it, and it will give us an extremely powerful and flexible working environment. This is our (updated) guide to “do-it-yourself network segmentation” where we’ll walk through how network segmentation can be accomplished practically with inexpensive equipment.įor our example, we’ll be using an ASUS RT-AC3200 as our hardware platform as it gives us relatively modern hardware (Wireless AC and Gigabit Ethernet) for a low price. This way should a security incident occur, you don’t risk entire network compromise – rather, it will only affect an isolated portion of your network. ![]() If you want to ensure the security of your network, network segmentation is a necessity (especially in this era of rampant Internet of Things (IoT) devices co-mingling with more traditional workstations). Network segmentation is not only for large corporations – you can segment your home network or small business network securely, and for a reasonable price, too.
