Try disabling OFDMA in the wireless settings, and also disable AP Isolation in the wireless advanced settings.

Make sure no devices are connected to the guest network if the guest network is enabled.

@Tony 

Thank you for your response. Disabling OFDMA has worked (AP Isolation was already disabled).

I do not know the technical details of OFDMA, but my understanding is it is one of the biggest features of 802.11-AX. So it is a bummer that I have to disable the feature to cast videos to my Chromecast devices.

@RaviChelikani 

If you were to re-enable OFDMA does that bring you back to the issue to verify if that affects your Chromecast?

@Tony - I've turned on the OFDMA again and so far I was able to cast to the chromecast devices. Any idea why turning it off and on has worked? I hope this is a permanent fix. Thank you very much for replying to my questions, appreciate it.

@RaviChelikani 

I've seen something similar with AP isolation where you needed to do that.

I would monitor it closely and should the issue return I would reach out to our support team.

Hello,

None of the devices (Windows/Android/iOS) that are connected to my AX11000 router are able to cast to any of the chromecast devices. I have Chromecast Ultra and Google Nest Home displays. Every time I restart the router the chromecast devices show up on all devices. But after sometime they disappear and so cannot cast to any of them. Restarting the router seems to solve the problem all the time. But it is a pain to restart the router that frequently. From other threads it looks like there are other people facing the same problem. Can you please look into this issue?

 

Thanks,

Ravi

I have the same problem with my AX11000.  Chromecast devices would disappear and if I rebooted the router they come back for a period of time before they disappear again.  I tried disabling OFDMA and that worked for only a short time before I can't see my chromecast devices again.  This time, I turned OFDMA back on without rebooting the router and the chromecast devices showed up again.  Will see what happens now and how long they will stay visible.

I'm hoping there's a firmware update for this soon because it's very annoying since I use chromecast quite a lot.

Yeah, it is frustrating. I've opened a ticket with TP-Link. there is no resolution yet. I've given them a copy of my settings and they said they'll try their device with those settings. I'll post here when I hear back from them.

Right now I had to toggle the OFDMA to off again to see my Chromecast devices... Looking forward to hear what they say about this...

@RaviChelikani 

I have same issues with AX1500. Strange thing is that it started to happen only a few days ago. Got the same problem with file sharing from home network ... Cpmputers show up then disappear

@SebastienJP 

If you haven't please open a ticket with the support team. Hopefully if they see more tickets this thing will be prioritized. When I opened my ticket I got a response that they will look into it. I gave them a backup of my settings as well so they can use my settings. I haven't heard back from them yet. All they gave me is a beta of the next version of the firmware. That definitely has reduced the number of times I had to restart. Here's the link to it (hopefully it still works)
