Description
IEEE 802.11b or IEEE 802.11g protocol, or work at 2.4 GHz with IEEE 802.11n protocol,
therefore enjoying a maximum transmission rate of 300 Mbps.
5 GHz WiFi network supports 11ac, 11a/n/ac mixed modes.
11ac: It indicates that devices complaint with IEEE 802.11ac protocol can connect to the router,
enjoying a maximum transmission rate of 866 Mbps.
11a/n/ac mixed: It indicates that all devices that are compliant with IEEE 802.11a or IEEE
802.11ac protocol, or work at 5 GHz with IEEE 802.11n protocol can connect to the router,
enjoying a maximum transmission rate of 866 Mbps.
WiFi
Channel
It specifies the channel in which the WiFi network works.
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.
WiFi
Bandwidth
It specifies the bandwidth of the wireless channel of a WiFi network. Please change the default
settings only when necessary.
20: It indicates that the channel bandwidth used by the router is 20 MHz.
40: It indicates that the channel bandwidth used by the router is 40 MHz.
20/40: It specifies that a router can switch its channel bandwidth between 20 MHz and 40 MHz
based on the ambient environment. This option is available only at 2.4 GHz.
80: It indicates that the channel bandwidth used by the router is 80 MHz. This option is
available only at 5 GHz.
20/40/80: It specifies that a router can switch its channel bandwidth among 20 MHz, 40 MHz,
and 80 MHz based on the ambient environment. This option is available only at 5 GHz.
