Issues with connecting for android devices only (specifically pixel 7a devices)

[01cooperl]

Hi all,

I have 26.1.6 and have been over the last few months having intermittent issues connecting to the network with two pixel 7a devices. The behaviour is that when they are successfully connected via wifi (using unifi access points), there is no issues accessing both local IPs as well as out to the internet. The devices, in no set pattern, drop off the wifi and do not connect with a "Saved / IP configuration failure" status on the android device.

Since this issue I have since migrated the DHCP server to Dnsmasq, ensured that the devices are using device MAC addresses (this was already the case), disabled IPv6 for all interfaces, ensured Router Advertisements are not enabled, checking Unifi settings to ensure there was no issues.

I have Windows, Mac, and other Android devices which are not pixel 7a which work without issues.

I have tried to look at the DHCP and live firewall logs to see what is happening, however I am really at a loss of what is happening short of setting up a fresh instance and starting again (a real nuke for two devices!).

Any advice or things to investigate would be greatly appreciated. Thank you for your help in advance!

And what do you see there?
Share it with us?

So If I understand this correctly, when you have the disconnection you get that popup or error message on those phones?

The Pixel phones sadly are know to such issues, there are several post on reddit reporting such issues across the pixel phone series. So its as well possible google just once again broke them with a software upgrade.

I had major problems with Unifi U-6 Lite and Pixel 6 and 6a devices. No problems with other wifi devices.  The first thing to check is the version of Unifi software.  Some of the Unfi versions simply did not work with Pixel devices.  I am currently at 10.3.58.  Earlier solution, I also found that I had to set the ipaddress and NOT use dhcp on the Pixel.  I do not know if that is still the case.  The problems went away with updates to Unifi and Android version  updates (currently version 16).  Connections were worthless until the slow progression of updates from Android and Unifi.
