Support the AP (wireless access point), the Client (Client), the Repeater (wireless relay), Bridge (wireless Bridge), the Router (wireless Router) five working mode
AP mode - the default work mode.This mode device is a wireless access point, support plug and play, no configuration.
The Router mode - this mode device is equivalent to a wireless Router, the wired interface as the WAN, the wireless LAN.Multiple wireless clients can share a broadband link on the Internet.
Repeater mode, use of equipment of the wireless relay function, realizes the wireless signal relay and amplified, and form a new wireless coverage area, finally achieve the goal of extending wireless network coverage.
Bridge model, use of equipment of Bridge function, first RM04 set up a wireless connection with the front end of wireless network, a wireless signals, and then itself to form a new wireless coverage, can effectively solve the problem of weak signal and signal blind spots, such as wireless coverage.
Client work mode - in this mode the AP for the AP is wireless Client, equivalent to a wireless network card.
