focusing on bandwidth through QoS
focusing on bandwidth through QoS
Hello, I’m new to routers and networking but I attempted to give my desktop PC priority over other devices at home for bandwidth. On the router’s interface I enabled QoS and included the IP addresses of the devices I want to manage download speeds. After completing the list, I saved it, checked the box to activate it, and set the QoS bandwidth to 2mbs. The issue is that even though my PC’s IP isn’t on the list, it still gets affected by the restriction. How can I fix this? Also, I have an Air6372SO.
I don’t have access to the exact configuration, so I can only offer possible assumptions. It’s likely the device was placed on a whitelist or exception list restricting bandwidth for certain clients. You might have entered an exception where only those users are allowed up to 2MBps. Consider deleting that list completely and restarting the modem/router afterward.
For QoS to function properly, the system needs to understand your overall bandwidth capacity so it can control traffic accordingly. The goal is for your router to discard packets rather than forwarding them to the ISP, meaning you should set a maximum rate slightly lower than your ISP limit—typically around 90% of that value. For example, with a 100Mbps download speed, you’d configure the router to allow only 90Mbps for all clients. Make sure you correctly interpret the "QoS Bandwidth" setting as a total allowance rather than per-device limits.
Initially everything was at 0. You want your PC to get 90% of the download speed, with the rest split among other devices. That’s achievable if you adjust settings properly.
Check if one "QoS Bandwidth" entry exists or if multiple fields are present. If just one, adjust it to 90% of your actual ISP speed.
The goal of QoS is generally to rank packets based on their type (for example, VoIP gets higher priority than file downloads) to ensure interactive apps remain stable and data doesn’t drop during busy periods. It focuses more on managing network resources for application needs rather than restricting bandwidth on individual devices.
I tried to adjust it to 90% speed, but it seems I might not reach my aim. Thanks for understanding.
You should be able to manage priorities effectively—there’s likely a method to set desktop as top priority. I can check your current QoS settings and provide a screenshot if you’d like.
