One problem: After the CSI tool is installed, a TCP packet with a size greater than 400 bytes cannot be sent out. Why? The test conditions are as follows: Computer A, without CSI tools installed; Computer B, with CSI tools installed. Both are connected to WiFi sent by OpenWRT, A -> B sends, 400 bytes of TCP packets, B can receive normally. However, when B -> A, a 400-byte TCP packet, A cannot receive it. Therefore, it is judged that the computer with the CSI tool installed has a problem with the sender. What causes it? Where can the driver be modified? Or can you increase the size of the allowed message by modifying the kernel parameters?
