TP-Link AC1200 QoS指南 帮助您优化网络性能与流量管理。
You're facing a common issue when configuring QoS on older TP-Link routers like the AC1200. It appears the system only permits QoS activation when NAT Boost is turned off. Disabling NAT Boost significantly reduced your bandwidth from 1Gb to around 100-150Mb. After researching, you found OpenWrt/LEDE as a potential solution, but you opted for version 1 instead of the recommended version 2. Many users believe this might be a hardware limitation, suggesting a new router or switch might be necessary. You're seeking advice from more experienced individuals to help resolve this problem.
I found QoS addresses bufferbloat issues based on advice from openwrt/fast/dslreports. I frequently play competitive first-person shooters and often experience connection problems because I download a lot on my laptop—probably because its receiver isn’t great. My internet speed is more than enough for the bandwidth, but my PC only manages up to 250 Mb/s, so it should handle the rest. The quality of my line is A+, yet bufferbloat stays between B and A, which affects my gaming. Also, during speed tests, my router’s CPU usage jumps to 85% or higher, which seems excessive for what I expect from it. I’m trying to keep my connection stable, and I suspect QoS is the starting point.
I think connecting your desktop straight to the modem avoids most problems in games. What’s your upload speed? Does enabling QoS fix the issue? Make sure you have sufficient bandwidth for QoS to work without affecting performance.
I recently attempted connecting my PC directly to the modem, but the router fails to receive the internet connection. No matter how many times I restart devices, the issue persists. Since I don’t have access to the modem’s login credentials, I’m left uncertain about troubleshooting steps. My upload speed ranges between 50-70 Mb/s, and it experiences the most bufferbloat. When I enable Quality of Service settings, internet performance drops sharply, capping at 150 Mb/s instead of the full 1 Gb/s. Disabling NAT Boosting worsens the situation.
The router reaching 85% CPU usage isn't always a concern, especially if you're playing games. Bufferbloat isn't necessarily a problem either, unless you're pushing your upload speed during gameplay. Keep in mind, tests that intentionally increase upload to check for bufferbloat are designed for worst-case situations, not everyday use.
You need to determine whether it's a modem or a gateway (a combination of both). Some modems have multiple Ethernet ports, which certain Docsis 3.1 models use to boost speeds beyond 1 Gbps. They essentially suggest avoiding 10 Gbps connections on consumer devices.
