Relay mode: Sometimes a device may be in the living room, but because of poor signal, the signal in the bedroom may only have one frame, which requires further expansion of wireless network. At this time, we can consider using another wireless router to expand the network through relay mode. The name of the "amplified" wireless signal is the same as that of the original wireless router signal, such as mobile phone, tablet, etc., which does not need to be manually switched and completely depends on the network to cover itself.
Features: When relaying settings, you need to connect to another WiFi signal, and keep the WiFi name settings completely consistent.
Application scenario: Expand the network and realize signal "roaming" within a certain range
AP mode: AP mode is quite special. Generally, it is only AP hotspot devices that have this function. At the same time, AP devices do not have bridging and routing modes, but support relay function. The difference between relay and AP hotspot is also very simple. Relay mode actually extends a wireless network by 1:1, and does not need cable connection, and both routers and AP devices support this mode; The AP mode uses the network cable to expand the WiFi signal, but it is not responsible for managing the network itself, which is equivalent to a switch with wireless function, which converts the wired signal into wireless, and other functions need to be realized by routers (IP allocation, network management, etc.).
Features: It is converted into wireless network through network cable, and has no management and routing functions.
Applicable scenario: Covering dead corner of signal, the function is similar to relay, but AP equipment does not need to be configured, so it is plug and play.
