    FAQ are frequently updated with latest information. In addition, you might find new firmware that either increase software functions or provide bug fixes for A.DUO. You can reach our on-line support center at the following link: http://www.airlive.com/support/support_2.jsp Since 2009, AirLive has added the “Newsletter Instant Support System” on our website.

  • Page 10: Dual Band Router Mode

    1.5.1 Dual Band Router Mode In Dual Band Concurrent mode, the radio1 works in 5Ghz while radio2 works in 2.4GHz mode. That means the A.DUO can provide Internet service to both 5GHz (like game network) and 2.4GHz (like PC network) at the same time.

  • Page 11: Dual Ap Mode

    1. Introduction 1.5.2 Dual AP Mode In Dual AP mode, both wireless interface of A.DUO are set as AP and provide hotspot service on each interface. Radio1 is set to 11a mode while Radio2 is set to 11g/b Mode (changeable to 11a also). This mode is most useful for Dual Band Hotspot function such as in the hotels, shopping malls, or offices.

  • Page 12: Wisp + Ap Mode

    In this mode, Radio1 (in 11a mode) acts as a client to connect with remote WISP Base Station. Radio2 (in 11g/b mode) works as an AP router to allow subscriber to share the WISP connection wirelessly. Using the A.DUO, WISP no longer requires 2 AP/CPE to provide wireless access in subscriber’s home or office.
