Features: Full function of wireless router:
:Default work mode. In this mode, the device works as a wireless access point, support for plug-and-play, and no configuration needed.
:In this mode, the device is equivalent to a wireless router, wired interfaces can be used as WAN, wireless used as LAN. Multiple wireless clients can share a broadband line to search the Internet.
:Use the radio relay function of the device, achieve the radio signal repeat and amplified, and form a new radio coverage area, ultimately attain the purpose of extending the coverage of the wireless network.
:With the Bridging function of equipment, firstly, the module RM04 establish a wireless connection with the front-end wireless network itself ,then sending the wireless signal, at the same time, form a new wireless coverage, signal weak and signal blind spot can be solved effectively.
:The AP to work in this mode for the main AP is a wireless client, the equivalent of a wireless network card.
