Feature
1.full function wireless router :
2.Support AP ( wireless access point ), Client ( wireless client ), Repeater ( radio relay ), Bridge ( wireless bridge ), Router ( wireless router ) five operating modes
3.AP mode - the default mode of operation . In this mode the device is a wireless access point supports Plug and Play , no configuration .
4.Router Mode - In this mode the device is equivalent to a wireless router , wired interfaces as WAN, wireless to LAN. Multiple wireless clients can share a broadband Internet line .
5.Repeater mode - Radio Relay function uses the equipment , wireless relay and amplify the signal , and the formation of new wireless coverage area , and ultimately to extend wireless network coverage purposes.
6.Bridge mode - use the device bridging function, first RM04 establish a wireless connection with the front-end wireless network and then send out a radio signal itself , the formation of new wireless coverage , can effectively solve the signal is weak and blind spots , such as wireless signal coverage problems .
7.Client Mode - In this mode the AP is a wireless client to the main AP , the equivalent wireless card.
