Cast to tv does not work (youtube, mobile screen share etc.). AP305C

invisible132 — Fri, 17 Jul 2020 03:41:26 GMT

Hi all,

I have an issue when “cast to tv” button on youtube is missing when connected on AP305C, while on AP122 everything works fine.

I’m not sure how mobile phone finds tv, but I guess broadcast packets is involved here and it’s not being forwarded correctly.

Does anyone has similar issue?

Hi,

The quick way to check it would be to perform a “show run-config” on CLI on the controller and to compare the assigned parameters to the different APs.

Something has to trigger this difference.

I am managing these AP’s from extremecloudiq, so I guess I won’t be able to do this.

I did ssh to AP, but didn’t noticed any valuable differences between configurations.

Configs added. Maybe someone could check it. Thanks.

You can compare the two texts here to see the differences: https://www.diffchecker.com/

Mainly it looks like you’re using a different radio profile between the two configurations.

I have checked every radio profile setting. There are some differences because hardware of these AP’s are different, but I couldn’t find any setting differences which could cause behavior like this.

I guess it could be software bug.

Hi,

It’s most likely multicast based discovery (like Bonjour, mDNS), make sure that when client connects to another AP, both client and TV reside still on the same subnet (I don’t see much details on this in pastebin and frankly speaking I still have to improve my XIQ AP cfg reading skills, I’m used to WiNG much more). If this is ok, you can check underlying switch port. If it’s the same port, it shouldn’t be a problem. If it’s a different port and client/server are on different APs, take a look at any security/storm control related settings that might prevent multicast traffic from passing thru between switch ports. If all is good here, I’d try to look around if there is a different default behavior regarding BUM traffic handling on these AP models, call GTAC eventually.

Hope that helps,

Tomasz

I must say I had no clue that this function is called cast to tv but it works for me.

Samsung TV with a Chromcast connected to it - AP305c - smartphone

I haven’t configured anything special on the AP.

Is the Chromcast and the cellphone in the same VLAN/subnet so they could see each other ?!

Yes. Actually I have connected AP302c in place of AP122. Same cable, same switch port, same network.

I’ve compared it with my AP CLI config and the only big difference is that you’ve enabled a lot of advanced features on the radio…. OFDMA uplink/downlink, radio-balance, band-steering, 80Mhz channel.

Could you just try it with a clone of the default AP305c device profile and change only the absolute necessary parameters to see whether that will change anything.

Could you also explain the involved devices in more detail i.e has the smart tv build in function or is a chromcast connected.

Do the involved clients connect to the 5GHz or 2.4GHz radio of the AP.

Could you post a screenshot of the client view for both involved clients.

Sorry for a late reply. I was on vacation.

I’ve tried using default profile with no success.

It is smart tv built in function. I’m using 2 different tv’s LG and Samsung brands.

TV’s are connected by cable, spmartphone/laptop connected to 5ghz. All devices are on the same vlan and ping from laptop to tv works well.

One thing that I’ve noticed that AP power led is blinking white, but I can’t see anything wrong on status page.

Hi again!

I’ve found a solution to this problem. Now I am able to see cast button in youtube.

Just disable “Broadcast and Multicast Handling” under SSID optional settings.
