This article mainly shows you "how to improve the stability of Raspberry Pi network". The content is simple and easy to understand, and the organization is clear. I hope it can help you solve your doubts. Let Xiaobian lead you to study and learn this article "how to improve the stability of Raspberry Pi network".

1) Modify vm.min_free_kbytes in/etc/sysctl.conf (8192 modified to 16384)

# rpi tweaksvm.swappiness=1#vm.min_free_kbytes = 8192vm.min_free_kbytes = 16384

USB drivers allocate memory from the kernel, which can run out when the network is heavily loaded, resulting in failures.

2) Add smsc95xx.turbo_mode=N at the end of/boot/cmdline.txt

dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline smsc95xx.turbo_mode=N rootwait

Disable acceleration mode. This modification will slow down the network speed but improve stability.

Adding a heat sink to the chip and a stable power supply that can input high currents will make your Raspberry Pi more stable.
