Fragmentation Threshold
The value defines the maximum size of packets, any packet size larger than the value will be fragmented.
If you have decreased this value and experience high packet error rates, you can increase it again, but it
will likely decrease overall network performance. Select a setting within a range of 256 to 2346 bytes.
Minor change is recommended.
RTS/CTS Threshold
Minimum packet size required for an RTS (Request To Send). For packets smaller than this threshold,
an RTS is not sent and the packet is transmitted directly to the WLAN. Select a setting within a range of
0 to 2347 bytes. Minor change is recommended.

‧ Long –“Long ” can provide more reliable communication.
‧ Short –“Short ” is suitable for high traffic wireless network.
