Description
By default, 20/40 MHz coexistence is enabled to prevent interference between WiFi
networks in your environment at the expense of the WiFi speed. If no other WiFi
networks are present in your environment, you can clear the Enable 20/40 MHz
Coexistence check box to increase the WiFi speed to the maximum supported
speed.
Note: 20/40 MHz coexistence applies to the 2.4 GHz band only.
The fragmentation length (the default is 2346), CTS/RTS threshold (the default is
2347), and the preamble mode (the default is Automatic) are reserved for WiFi
testing and advanced configuration only. Do not change these settings unless
directed by NETGEAR support or unless you are sure what the consequences are.
Incorrect settings might disable the WiFi function of the modem router unexpectedly.
