Configuring Cisco 1702i Autonomous access point for use with Chromecast

Assuming you’d like to connect a client computer to your chromecast via the same WLAN on your Cisco AP, all you need to do is follow the below steps.

Assumptions:

  1. The Cisco AP is configured with only a single SSID, and that SSID happens to be associated with vlan 2.
  2. You are broadcasting the WLAN on both radios
  3. All the required configuration to support clients (SSID, Auth, etc) is already setup

Instructions:

  1. Login to your AP using the command line, issues a show run
  2. The output of your show run command should have some lines similar to what’s below:

!
interface Dot11Radio0.2
encapsulation dot1Q 2
no ip route-cache
bridge-group 2
bridge-group 2 subscriber-loop-control
bridge-group 2 spanning-disabled
bridge-group 2 block-unknown-source
no bridge-group 2 source-learning
no bridge-group 2 unicast-flooding
!
interface Dot11Radio1.2
encapsulation dot1Q 2
no ip route-cache
bridge-group 2
bridge-group 2 subscriber-loop-control
bridge-group 2 spanning-disabled
bridge-group 2 block-unknown-source
no bridge-group 2 source-learning
no bridge-group 2 unicast-flooding
!

So if our SSID is affiliated with vlan 2, we’ll need to issue a command to each of our sub interfaces using that vlan: Dot11Radio0.2 and Dot11Radio1.2

Enter the following commands:

  1. # config t
  2. (config)# interface Dot11Radio0.2
  3. (config-if)# no bridge-group 2 port-protected
  4. (config-if)# exit
  5. (config)# interface Dot11Radio1.2
  6. (config-if)# no bridge-group 2 port-protected
  7. (config-if)# exit

Now we’ll also need to globally stop IGMP snooping, we’ll enter this additional command from global config mode:

  1. # config t
  2. (config)# no ip igmp snooping
  3. (config-if)# exit

Lastly just save your config and test, you should now be able to connect to the chromecast from a wireless client connected to the same WLAN as the chromecast, or if you followed the previous post on configuring a sonicwall for use with a chromecast (located here), a wired client connected on another interface of your sonicwall.

    Hi!
    I brought a 1702i to use it as a autonomous AP but I cannot get it into autonomous mode, how did you do this?

    Model: AIR-CAP1702I-E-K9

    Thanks in advance from Denmark!
