Google devices (Android 15, ChromeOS) losing WiFi connectivity

Question

Greetings,Since November 2024 or earlier, two of four devices at home have intermittent losses of WiFi connectivity. We're at a dead-end with troubleshooting, and so is Cox Complete Care. Here are some facts so far:HP multifunction printer (2011) on Ethernet has no issuesMoto g Play (2021) Android 11 on same WiFi: no issues, no interruptions, fast downloads and streaming.WiFi connectivity only for this device, which stays at home.Panoramic WiFi routers indicate no outages. This is the third router we've swapped out with same behavior. Our home connection is DOCSIS 100Mbps with over 10 years of superb reliability.Router factory-reset has been performedConfiguration to ensure maximum connectivity and minimal complexityNo MAC filtering, firewall interference, or other security blocks are evident3 types of system logs indicate no relevant entries96% uptime on the WiFi connections to the Google devices. This is an intermittent and brief interruption.The main symptom is a notification: '<SSID> has no Internet access' which will persist awhile, then the device may dissociate entirely from the Panoramic WiFi signalOn the Pixel 8 Pro, Cox Mobile data is reliable and operating correctly for Internet accessSeveral Android updates since this issue began, possibly as early as Android 14Several [private] DNS configurations have been tried, with no reliefPixel phone generally exhibits the same glitch at same time as ChromeOSOn the Acer Chromebook, Ethernet connectivity is reliable and uninterrupted at these timesWiFi configuration has been modified and reset in every imaginable permutationCox Support was unable to disable IPv6 or otherwise simplify the variables so that more troubleshooting could proceed. I told them, if a technician was dispatched, that they'd find no issues, because this is intermittent, and doesn't seem to be a Cox Equipment issue at all.So Google's OS between 13-15 somehow incompatible with Cox Panoramic WiFi. Here are some hypotheses:Dual-stack IPv4/IPv6 is very problematic for any customer or any service provider.Google's 'Internet access detection' may be deceived by poor connectivity for one protocol.Not all sites/apps have dual-stack connectivity, but is Google checking something specific?DNS always suspect.Disabled/re-enabled Private DNS.DNS is dual-stack as well; see above.Surely Google's access test relies on DNS in some way.All the custom settings applied locally.Why is connectivity excellent, 96% of the time when we're not tinkering with it?Devices updated, settings reset, routers swapped; no relief from configuration tweaks.Malware/threat detection by Cox network?Locking out the WiFi connection in a reaction to a threat from customer's network, but why is Ethernet unaffected?No warning emails or comments from tech support?Radio-interference issuesThis is a dense multifamily housing community.Congested 2.4GHz WiFi band was disabled with no change in symptoms.Android 11 has no issues, and streaming is normal, and download speeds are fast, with full bars.Next steps, I'll follow up with Google Support, increase WiFi logging on the Pixel phone, and wait for another glitch.

By chance do you have Private DNS and Adaptive connectivity enabled?  I could see both of those causing network connection problems.  I have those both off on my Pixel 8 Pro and no issues.

IPV4 and IPv6 isn't the issue. Depending on your devices, it could be several things. First, ensure your pano router is out in the open, NOT in a smartbox, NOT behind anything, (Especially a TV), and not UNDER anything. It HAS to be in the open, and raised as high as you can place it, so that it reduces the number of objects that are physically between the router and the device trying to reach it.
