Contents: How to setup AP to share a Internet connection or to access your private LAN
Remark: Tested on AirOS version 3.3.1

Network Topology

We'll consider this simple network topology:

  • 1 Router/Gateway connected to Internet and/or private LAN (IP Address: 10.10.10.254/24)
  • 1 Switch for private LAN (optional)
  • 1 AP AirOS device directly connected to Router (IP Address: 10.10.10.253/24)
  • 1 or more Wireless Clients (Notebook, WiFi-Phone, other Wireless devices...)
  • The Router assign IP Address to network devices by DHCP Server. Alternatively, if you prefer, you can set static IP Address on Client.

Devices configuration

Router Setup

Router can be your ISP ADSL Router, a Ubiquiti Routerstation or a Mikrotik RouterBoard plus Ethernet Modem... please refer to device manual.

  • Set your Internet connection according to ISP paramenters (WAN IP Address, DNS IP Address, ...)
  • Set LAN IP Address/SubnetMask: 10.10.10.254/255.255.255.0 (10.10.10.254/24)
  • Enable DHCP Server to assign IP Address to Network Devices (e.g. range Client IP Pool from 10.10.10.1 to 10.10.10.100)

AirOS AP Setup

Connect your PC directly via Ethernet cable to AirOS Device to configure as AP and login into WEB-GUI.

Note: need to configure your PC with an IP Address of same Subnet of AirOS device.
By default, AirOS device have 192.168.1.20/255.255.255.0, you can assign your PC IP Address like: 192.168.1.1/255.255.255.0 (see this guide)

  • In LINK SETUP Tab, set:
    • Wireless Mode: Access Point
    • SSID: yourSSID (or any other string to identify your WLAN)
    • Country Code: set according your country
    • IEEE 802.11 Mode: B/G mixed (assuming devices running in 2.4 GHz)
    • Channell Spectrum Width: 20MHz
    • Channel: 1 - 2412 MHz (or any other free channel)
    • Output Power: 10 dBm (or check Obey Regulatory Power according your country law)
    • Data Rate, Mbps: 54, Auto
    • Security: WPA (or any other, supported by Wireless Client)
    • WPA Preshared Key: yourpassphrase (this is a secret key for your WLAN, minimum 8 printable ASCII chars, maximum 63)
    • Click "Change"
    • Wait until process is complete and click "Apply" to confirm new configuration (or click "Discard" to refuse).

Note: we suggest to set Wireless Security only after you are sure that Wireless Client are able to connect your AP.
Note: not all Wireless devices support all Wireless Security (WEP, WPA, WPA2, ...)

  • In NETWORK TAB, set:
    • Network Mode: Bridge
    • IP Address: 10.10.10.253
    • Netmask: 255.255.255.0
    • Gateway IP: 10.10.10.254
    • Primary DNS IP: 10.10.10.254 (or DNS IP provided from your ISP)
    • Secondary DNS IP: as Primary DNS IP
    • Click "Change"
    • Wait until process is complete and click "Apply" to confirm new configuration (or click "Discard" to refuse).
    • Now the devices should be reachable on new IP Address 10.10.10.254.
    • Remember to assign to your PC a IP of Subnet 10.10.10.x (e.g.10.10.10.200/255.255.255.0)

Client Setup

Wireless Client devices can be: Laptop (whit Windows, MAC, Linux...), PDA, WiFi-Phine, WiFi IP Cam... refer to manual.

In TCP/IP Network Section:

  • If supported, set device to obtain Address IP automatically
  • Otherwise set statically:
    • IP Address: any free IP 10.10.10.x/255.255.255.0
    • Gateway: 10.10.10.254
    • DNS: 10.10.10.254 (or DNS provided by your ISP).

In Wireless Section, set the same parameters used in AP Setup:

  • WiFi Channel
  • Wireless Security (WEP, WPA, WPA2,...)

Monitoring Associated Clients/Stations

  • In MAIN TAB, select Show Station from Extra info menu.
    .
    A popup window will list Associated Stations For detailed info, click on the MAC address.
