It depends on what feature you're turning off. Checking for potential issues is always a good idea.

In short: By switching off NAT Boost, my router behaves strangely. I’m worried we won’t be able to use Wi-Fi for our online lessons. I need QoS enabled so my phone gets priority without my family noticing any changes. I’ve dealt with Wi-Fi issues before—my older brother once broke it and got in trouble for playing games. My situation is similar; I have three brothers, and during the recent holiday, we had to adjust our online routines.
Our school introduced an “Online synchronise lesson,” requiring us to wake up at 6:40 AM. This added extra load on our network, causing delays and slow speeds. We’re using different devices with varying Wi-Fi standards—my Asus Transformer Book T100Chi (Wi-Fi 4), my brother’s Honor Magicbook (Wi-Fi 5), and another laptop with a weak adapter.
My third brother uses a Gigabit LAN port, but he’s not using it properly. He ended up replacing our old router, which was much faster, because it kept dropping connections. Now he’s using a subpar Wi-Fi USB adapter. I’m trying to fix this by finding a better adapter and maybe switching back to the original router.
I noticed in the router settings that QoS is disabled when NAT Boost is active. This means my phone’s internet speed won’t be fast enough, even if I don’t realize it. I want to keep my family unaware of any changes while blocking other features until I’m ready.
Please let me know what you think—I’m trying to balance performance and privacy here.
These technologies enable low-end CPUs in devices like routers to achieve speeds up to 1 Gbps. They work by using software tricks—such as bypassing certain network filters—and some hardware capabilities. However, they often clash with advanced router features like QoS, and turning them off can restrict your maximum WAN speed. The exact limit varies by router model and its CPU performance. Generally, a modern router can support about 300 Mbps even with NAT acceleration disabled, so the impact is mainly tied to your internet connection speed. If you're on a slower connection like 30 Mbps, disabling NAT acceleration won't noticeably affect performance.
