SBG6400 (v1.3.x): Scan Wireless AP Tool

The SBG6400 now includes the ability to scan for existing Wireless APs (Access Points) in aiding the installation and configuration of the SBG6400 in noisy WiFi areas.  This tool is used to determine the wireless channels that are in use by other Wireless APs and verifies which channel to use in order to eliminate any wireless interference.  Once it is determined which channels are in use, verify the channel with the least amount of users.  Making the best channel selection for the SBG6400 requires a close analysis of the scan results and also determining which channel is used least for best connectivity.  The scan results contain the following:

• Network Name - List the SSIDs of Access Points seen by the SBG6400
• Security Mode - Displays the type of security and encryption in use 
• Mode - Current Mode (generally managed)
• PHY Mode - Available 802.11 operating mode
• RSSI - Receive Signal Strength Indicators in dBm, Power Level seen by the SBG6400 at the time of the snapshot
• Strength - Wireless signal strength of nearby Access Points to the SBG6400
• • Green Star indicates weak signal strength
  • Yellow Star indicates moderate signal strength
  • Red Star indicates strong signal strength
• Channel - Current WiFi transmit channel of nearby Access Points
• BSSID - Basic Service Set Identifier (MAC Address of nearby Access Points)

This document describes how to use the Scan Wireless AP Tool and to change the wireless channel.

5. Click the Login button.  The Home page will appear.
   
   
    
6. Move the mouse cursor over the Wireless tab and select 802.11 Radio from the drop-down submenu.  The Wireless - 802.11 Radio page appears.
   
   
    
7. Move the mouse cursor over the Wireless tab and select 802.11 Radio from the drop-down submenu.  The Wireless - 802.11 Radio page appears.
    
8. On the Wireless 802.11 Radio page, click the Scan Wireless APs button.  A Pop-up window with a list of nearby wireless access points appears.
   
   NOTE: Pressing the Scan Wireless APs button executes the tool and will Pop-up another window displaying the scan results.  Be sure to disable the Pop-up blocker on the browser to allow the tool to work. 
   
   
    
9. On the Pop-up window, determine which channel would be the best to use by verifying which channel is used the least or not used at all.
   
   
   
   NOTE: In the example above Channel 6 is highly used, while Channel 11 is moderately used.  The best Channel available to use is Channel 1 or the remaining channels not in use.
   • Network Name - List the SSIDs of Access Points seen by the SBG6400
   • Security Mode - Displays the type of security and encryption in use 
   • Mode - Current Mode (generally managed)
   • PHY Mode - Available 802.11 operating mode
   • RSSI - Receive Signal Strength Indicators in dBm, Power Level seen by the SBG6400 at the time of the snapshot
   • Strength - Wireless signal strength of nearby Access Points to the SBG6400
   • • Green Star indicates weak signal strength
     • Yellow Star indicates moderate signal strength
     • Red Star indicates strong signal strength
   • Channel - Current WiFi transmit channel of nearby Access Points
   • BSSID - Basic Service Set Identifier (MAC Address of nearby Access Points)
10. Once the channel has been determined, close the pop-up window.
11. On the Wireless 802.11 Radio page,
    a.   Control Channel - Click the drop-down tab and select the desired channel.
    
    NOTE 1: It is recommended to leave the Channel default setting at Auto and restart the SBG6400.  The best Wi-Fi channel will be selected upon restart.  Keep in mind that the connected Wi-Fi clients temporarily lose Internet connection when the SBG6400 is restarting.
    
    NOTE 2: When choosing to set the Wi-Fi channel, it is recommended to set the channel to 1, 6, or 11 for better performance and stability because they do not overlap.  Other Wi-Fi channels overlap and degrade performance. 
    
    b.   Click the Apply button.
