The bandwidth limiter allows the user to control and monitor Internet traffic. This issue can occur on new and existing Asus routers, and the reasons can vary, including incorrect network configuration and hardware failure. In this article, we take a look at a few troubleshooting steps to help you resolve the Asus bandwidth limiter not working problem quickly.

How do I fix the Asus bandwidth limiter not working?

1. Use a third-party bandwidth limiter 

While the built-in bandwidth limiter offers basic network monitoring and traffic control features, specialized bandwidth limiter software like PRTG Network Monitor is an excellent tool for network monitoring and traffic management. PRTG Network Monitor specializes in capturing networking traffic in multiple ways. It uses protocols such as SNMP, packet sniffing, and NetFlow to help you manage and monitor your network. On the routers that support Netflow, sFlow, or jFlow, you can use PRTG Network Monitor to control bandwidth usage. Compared to packet sniffing, protocol-based bandwidth control reduces CPU loads on the server.

2. Disable IPv6 on Asus router

Next, restart your PC. Connect your computer to the network and check if the Asus bandwidth limiter not working issue is resolved. SPONSORED According to Asus, the network bandwidth limiter stops working if you turn on IPv6. This is due to the bandwidth limiter not supporting IPv6 for the router.

3. Disable NAT Acceleration 

After the reboot is complete, reconnect your router and check if the Asus bandwidth limiter not working problem is resolved. NAT acceleration is a set of hardware tools and software features to speed up a fast Internet connection on NAT routers. Asus routers support both QoS bandwidth limiter and NAT acceleration functions. However, these two functions cannot work at the same time. So, if you want to use a bandwidth limiter, make sure NAT acceleration is disabled.

4. Update Asus router firmware 

The Asus bandwidth limiter not working issue in your router can occur due to several reasons. First, make sure the NAT acceleration is disabled, and turn off IPv6 as it is not supported by the bandwidth limiter feature. Additionally, use a specialized bandwidth limiter for advanced network monitoring and control features. As a last resort, update and reset your router settings to fix the issue.
