Wireless - configure a 1941W router with a single subnet on wired and wireless interfaces

The 1941W router is a home/small business router that has an integrated wireless access point. It is possible to configure this device to use the same subnet for both wired and wireless networks by creating a bridged network configuration. This can be done like so:

  • Configure the LAN interfaces:
    • Connect your wired devices to the LAN interface on the router.
    • Assign an IP address and subnet mask to the LAN interface using the “interface” command in global configuration mode.
  • Configure the wireless interface:
    • Enable the wireless interface using the “interface wlan0” command in global configuration mode.
    • Configure the SSID and security settings for the wireless network using the “ssid” and “encryption” commands in the WLAN interface configuration mode.
    • Assign the same IP address and subnet mask to the wireless interface as the LAN interface using the “ip address” command in the wlan interface configuration mode.
  • Bridge the interfaces:
    • Create a bridge group using the “bridge” command in global configuration mode.
    • Add the LAN and wireless interfaces to the bridge group using the “bridge-group” command in their respective interface configuration modes.

Once you have completed these steps, the wired and wireless interfaces will be bridged and devices connected to either interface will be on the same layer 2 network segment and share the same IP subnet.
