Found the thread above from a month ago, but without the "not really" in the title, and sadly it is closed, but this is a pretty significant issue for anyone running a secure network and using Chromecast. Chromecast is DoS-ing my netgear router running in AP mode.
Really this is an issue regarding Chromecast on a network where the router, in my case a netgear R7800, running in AP mode vs router mode. I have a firewalla gold and the r7800 needs to be in AP mode for the firewall to do its best work. Apparently chromecast blitzes your network with a ton of traffic, apparently thousands of packets, and crashes routers in AP mode. YES literally crashing the router, hard line and wifi are dead and an AP power cycle is the only remedy. Some Google update broke the chromecast and R7800 relationship late on Feb 27th or early on Monday the 28th. Nothing else on my end changed. I control the updates for the router, running Voxel's firmware on the R7800. The chromecast worked for months before that day. Called Google support for the chromecast and they were no help at all, giant surprise.
An identical issue from 2018 was all I could find out there, and in that case, it seems like chromecast would flood the network with some sort of advertising packets causing a bunch of different vendor's network devices to crash. Google fixed it but it looks like it resurfaced at least for my model. Going to follow up with voxel. Let's see what happens?!
Only just seen your post here.
Identical issues experienced by me and a few others with similar set-up. Have put a few posts on here with no response.
See this for protracted commentary:
Issue started same time (end Feb/beginning of March) so clearly a server side coding change/bug.....but one that has not really been acknowledged and most certainly not resolved for 2 months!!
Hey there kamaniwanalaya,
I apologize about the late response on this, thank you for being patient! Were you able to fix that crashing issue? If not, we'd be happy to look into it, as I can imagine this issue is quite frustrating. First, please reboot the router and make sure all of your devices' firmware is up-to-date. Afterwards, if the problem persists, I would recommend that you get a hold of Chromecast support as they would need to see your router logs for packet requests, and we don't want you posting that to the forum.
I hope that helps, and if you have any other questions or concerns for me, please let me know.
Hi kamaniwanalaya and rhammond84,
Just checking in to make sure that you've seen our response. Please let us know if you have other questions or concerns as we will be locking this in 24 hours if we won't hear back from you again. Feel free to start a new thread and we'll be happy to help.
I got specific support from senior engineering support to resolve an issue/bug having given access to my Home Graph. This has resolved the issue.... But it still exists for other customers. There's no clear route for them to get the senior support to resolve the bug. So issue is not structurally resolved - that needs to be worked internally.
Hey there rhammond84,
I'm sure that the Senior Engineering Support agent already took the logs, but if you have the time, would you be able to submit feedback about this issue? That way, we can have all the details about this issue, and the Engineering team can look at what is causing this to occur. If anyone else is also experiencing this, please reach out to support and submit feedback as well.
I look forward to your response on this, and if you had any other questions, please let us know.
