As follows:
DTIM threshold: is the frequency at which data packets are sent wirelessly when using a wireless router. 1 is the lowest interval and 255 is the highest.
Fragmentation threshold: If the fragmentation is too small, the efficiency of router processing will be reduced. If the fragmentation is too large, it will cause errors. If a data packet is too large, it will have to be fragmented. The maximum transmission unit of the Internet is 1500.
But if you want to make the connected device reach the highest operating speed, adjusting to the maximum value of 255 will not work. Each device has different requirements for DTIM, so you need to use testing software to test yours one by one. The device operates at optimal speed.
Standard wireless routers support the selection of 11 channels. However, choosing a device set to channel 3 will cause interference to devices using channel 1 and channel 6. Choosing a device set to channel 9 will interfere with devices using channel 9. Interference occurs with devices on channel 13.
In order to avoid channel conflicts in our wireless router, we can try to enter the background management system of the device and adjust the channel parameters to uncommon wireless channels.
For example, you can set the wireless router's channel to channel 1 or channel 6, or you can set it to channel 11 or channel 13. These channels are often less prone to channel conflicts.
