Introduction

Wireless Repeater (http://en.wikipedia.org/wiki/Repeater) or Network Extender From UBNT Forum (http://ubnt.com/forum/viewtopic.php?t=7204)

Typical scenario is to install a Network Extender device to provide wireless signal to Clients that cannot be reached from AP #1 (poor signal level). We consider this simply network topology:

• 1 Router connected to Internet and/or private LAN (IP Address: 192.168.1.254/24)
• 1 AirOS device AP #1 directly connected to Router (IP Address: 192.168.1.21/24)
• 1 AirOS device AP #2 connected via wireless to AP #1 (IP Address: 192.168.1.20/24)
• 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 to Clients.

In this schema, AP #2 is a Wireless Repeater device.

Configuring

Minimal configuration:

• Nall AirOS devices in AP-WDS mode
• Bsame SSID
• same Channel
• enter mutual WDS Peers (or enable Auto WDS, not recommended)

AP #1 Setup

• Network Mode: Bridge
• Bridge IP Address: Static
• IP Address: 192.168.1.21
• Netmask: 255.255.255.0
• Gateway IP: 192.168.1.254
• Click Change button to confirm
• IClick Apply button to apply changes
• Wait until process is complete

• Wireless Mode: Access Point WDS
• WDS Peers: 00:15:6D:B6:6D:4E (WLAN MAC of AP #2, you can see on MAIN Tab of AP #2)
• SSID: mywlan (or any stringh to identify your WLAN, but the same for all WDS Peers)
• Country Code: set according your location
• IEEE 802.11 Mode: B/G mixed (assuming devices running in 2.4 GHz band)
• Channell Spectrum Width: 20MHz
• Channel: 1 - 2412 MHz (or any other free channel, but the same for all WDS Peers)
• Output Power: 10 dBm (or check Obey Regulatory Power according your country law)
• Data Rate, Mbps: 54, Auto
• Click Change button to confirm
• Click Apply button to apply changes
• Wait until process is complete

AP #2 Setup
