It specifies various protocols adopted for wireless transmission.
2.4 GHz WiFi network supports 11b, 11g, 11b/g mixed and 11b/g/n
mixed modes.
11b/g/n: It indicates that all devices compliant with IEEE 802.11b or
IEEE 802.11g protocol, or work at 2.4 GHz with IEEE 802.11n protocol
can connect to the 2.4 GHz WiFi network of the router, therefore
enjoying a maximum transmission rate of 300 Mbps.
11b/g: It indicates that devices compliant with IEEE 802.11b or IEEE
802.11g protocol can connect to the 2.4 GHz WiFi network of the
router, enjoying a maximum transmission rate of 54 Mbps.
11b: It indicates that devices compliant with IEEE 802.11b protocol
can connect to the 2.4 GHz WiFi network of the router, enjoying a
maximum transmission rate of 11 Mbps.
11g: It indicates that devices compliant with IEEE 802.11g protocol
can connect to the 2.4 GHz WiFi network of the router, enjoying a
maximum transmission rate of 54 Mbps.
It specifies the operating channel of a WiFi network.
By default, the wireless channel is Auto, which indicates that the
router selects a channel for the WiFi network automatically. You are
recommended to choose a channel with less interference for better
wireless transmission efficiency. You can use a third-party tool to scan
the WiFi signals nearby to understand the channel usage situations.
It specifies the bandwidth of the wireless channel of a WiFi network.
Change the default settings only when necessary. By default, the
wireless bandwidth is Auto.
40MHz: It indicates that the channel bandwidth of a router is 40
MHz.
20MHz: It indicates that the channel bandwidth of a router is to 20
MHz.
