Google Chromecast and AP-7522I

joesatriani — Fri, 27 Mar 2020 17:09:06 GMT

Hi, I have this device and I have a problem with Google Chromecast.

Chromecast connects to wifi but my phone doesn’t find the Chromecast and cast doesn’t work.

Can you help me please?

Hi Joe,

Experienced same issue and this helped resolve it: https://gtacknowledge.extremenetworks.com/articles/Q_A/why-Chromecast-is-blocked-by-a-Wing-AP

In my case it was the "BROADCAST-MULTICAST-CONTROL" ACL. Once disabled Chromecast worked as it should.

Hope this helps,

Chris

Download, install and run Putty.exe
Select the SSH radio button
Enter IP address of the AP in the Host name (IP address) field and click Open
When prompted with security popup select “Yes”
Log into the AP using the same credentials you would use when logging in via GUI
Enter the following commands:

>en

#show run wlan <wlan name> (enter name of wlan the Chromecast should be connecting to)

Do you see the following lines in the output:

#use ip-access-list out BROADCAST-MULTICAST-CONTROL

#no client-client-communication

If you do, proceed:

#conf t

#wlan <wlan name> (enter name of wlan the Chromecast should be connecting to)

#no use ip-access-list out

#client-client-communication

#com wr

Install the best practices firewall policy per these instructions if not done yet:

Best Practices firewall policy

Thank you,

Chris

From your output:

Casa#show run wlan 5
wlan 5
ssid Telecom1567725
vlan 1
bridging-mode local
encryption-type ccmp
authentication-type none
no client-client-communication
no fast-bss-transition over-ds
wpa-wpa2 psk 0 ----
use wlan-qos-policy 5

Remove this and test:

#conf t

#wlan wlan 5

#client-client-communication

#com wr

#show run wlan 5

Also make sure you are on the latest firmware.

Did you implement the best practices firewall policy yet?

How to remove this? excuse me but I don’t understand.

Can you help me for check the firmware version?

Re: Google Chromecast and AP-7522I

Christoph_S — Fri, 27 Mar 2020 22:10:14 GMT

Run putty.exe
Select SSH radio button
Enter IP address of AP and click Open
Log into AP and type the following commands

conf t press enter

WLAN wlan 5 press enter

client-client-communication press enter

com wr press enter

OR an easier way for you may be to follow these instructions from GUI:

https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-enable-client-to-client-communication-Wing-Express

For the version just type the command: show version

or from GUI go to Configuration » Access Points » You should see the version in the Firmware column.

Thank you,

Chris

Firmware is

Re: Google Chromecast and AP-7522I

Radio 1 should be 2.4GHz or off if you don’t want to use it and radio 2 should be set to 5GHz.

Firmware is dated but not too badly.

If you want to upgrade you will need to have a valid support contract to be able to download the firmware.
