ASUS Router Configuration GUI Continued
One of the features you need to look for when purchasing a router is to ensure the router supports Guest networks. What is a guest WiFi network? It’s a separate WiFi SSID / Network from your main network and can be restricted so that users on the Guest network cannot reach your internal network servers, computers, or services. This is great for when family is visiting where they may bring devices that are already compromised and instead of them compromising the rest of your network, they are contained within the Guest network to keep things secure.
Below is a screenshot of what this looks like and how to configure them. With this particular router you can create up to three separate Guest networks per band (2.4GHz and 5GHz). I always create one with -Guest and 5G-Guest to indicate the difference. One nice feature that ASUS provides us is the ability to restrict users of your Guest network by time limits. This may not be as useful in a home environment but a small business like a coffee shop, it could be very beneficial.
One area where ASUS has spent a lot of time it seems is on the AiProtection. AiProtection works with Trend Micro to provide real-time network monitoring to detect malware, viruses, DDoS, and other intrusions before they reach your internal network. You can also enable so fairly decent Parental Control options for your kids and their devices such as iPads or other tablets.
First let’s take a look at the Network Protection settings of this ASUS wireless router. You can see that you can scan the router to generate a security assessment, enable site blocking of known malicious sites, block common exploits with the vulnerability protection, and also prevent infected devices from talking to your network.
The security scan shows some recommended steps that you should take to help secure your wireless router. You can click on each of the weak items and you will be taken to the config page for that item to address it. You can also click Secure Your Router and it will take care of the settings all for you.
You can modify the Alert Preferences under the Infected Device Blocking section. This will send an email to you when the router detects that a device is infected with a virus.
The Parental Controls tab allows for you to enable Web and Apps filters. This is on a per device (Mac Address) basis and you can configure what content categories you wish to block. I think this is a great addition to a wireless router and traditionally only seen in paid-for-subscription higher-end routers and firewall devices. You can also configure Time Scheduling on a per device level as well. Perhaps you wish to keeps your kids off the Internet before 9AM on the weekends or after 10PM at night?
One of my favorite features of this ASUS router web-GUI is the ability to easily monitor the traffic going through the network. With the WAN/LAN Bandwidth Monitor you can see your real-time upload and download statistics but you can also see the real-time traffic stats for each of the connected devices.
Furthermore, if you enable the Apps Analysis option you can drill down the devices to determine what application or service is using all of the bandwidth on a particular device. As you can see below, I have a wireless bridge connected to a TV which is streaming Netflix.. You can see that very easily in the graph below.
Enabling the Adaptive QOS feature, is very simple and easy to do. Once enabled you can drag-in-drop the different categories between high and low priority. The high priority ones will be granted the most bandwidth and the low ones will have limited when demand is high.
The web history tab give you some insight into the domain’s the different devices on your network are attempting to hit. This can be useful for watching your kids or for identifying malware or viruses attempting to phone home.
The last tab, Traffic Monitor gives you traffic graphs in real-time or over-time for all channels of traffic on your router. This is for WAN, Wired, and also 2.4GHz and 5GHz WiFi traffic.
