How do I configure Wireless Radio?

The Radio screen allows you to configure the wireless radio, including the country, channel number, and bandwidth control.

  1. Login into the device as described in the “How do I log into the modem’s Web User Interface?” FAQ.
  2. Select Wireless on the main menu.
  3. Select Radio from the left side menu.

  • Wireless Interfaces – Displays the wireless name (SSID) and the device MAC address.
  • Wireless – Displays the wireless radio’s status (Enabled or Disabled).
  • Country – Defines the country where the device is used.
  • 802.11 Band –Defines the 802.11 as either 2.4 GHz or 5 GHz. Note: The distance coverage for 5GHz is less than for 2.4GHz.
  • 802.11n-mode – Sets the wireless networking standard. Default is set to Auto, to use 802.11 n mode when possible.
  • 802.11 N Support Required – Defines whether 802.11n support is required (On) or not (Off).  “On” selection forces the gateway to 802.11n mode and clients must support 802.11n.
  • Bandwidth – Sets the bandwidth to 20 MHz or 40 MHz. For 40 MHz, set the sideband to lower or upper 20 MHz. 40 MHz channels double the channel width. This allows doubling the PHY data rate over a single 20 MHz channel.
  • Sideband for Control Channel (40 MHz only) – Only when using 40MHz Bandwidth should you choose the Lower or Upper 20MHz.
  • Control Channel – default setup is Auto.  Selects a specific channel to deploy the wireless network.  This allows you to set the operating frequency/channel depending on your particular region.  Channel selection can have an impact on wireless networking performance.
  • Regulatory Mode –Defines whether the Regulatory Mode is set to Off, 802.11d, or 802.11h.
  • Pre-Network Radar Check – Defines the number of seconds to check for radar on a channel before establishing a network.  Current specs specify 60 seconds.  Range 0-99.  Zero disables checking.  Designed so access points avoid channels that contain radar systems.  Used for 802.11h only.
  • In-Network Radar Check- Defines the number of seconds to check for radar when switching to a new channel after a network has been established.  Current specs specify 60 seconds.  Range 10-99.  Cannot be disabled.  Designed so access points avoid channels that contain radar systems.  Used for 802.11h only.
  • TPC Mitigation (dB) – Defines the transmitter power control (TPC) mitigation setting as 0 (off), 2, 3, or 4.
  • OBSS Coexistence –Enables or Disables overlapping BSS coexistence.
  • STBC Tx –Sets the space-time block codes (STBCs) for the transmitting antenna.
  • Apply – Saves all screen changes when clicked.
  • Restore Wireless Defaults – Restores the factory default settings for wireless configurations when clicked.
  • Scan Wireless APs – opens a new window with a list of Nearby Wireless Access Points, including the corresponding Network Name, Security Mode, PHY Mode, RSSI, Channel and BSSID.  Click Refresh to update the Wireless AP table.
