DeletedUser115 It has been a while. I wanted to give as much data as I could in regards to the above issue and suggestion...
After having several people over the last year connect to my home network and perform some stability tests using Android and iOS devices, all other devices had stable wi-fi connections for hours under data transfer load. My Pixel 4a 5G with GrapheneOS also performed as expected in regards to Wi-Fi stability connection, whereas the Pixel 6 failed as before.
Taking the Pixel 6 to other network locations along with the 4a 5G pixel also had similar outcomes.
Needless to say, the Pixel 6 Wi-Fi dropping is an issue with the unit, and not the network.
Just today, I had a new Pixel 8a arrive. I ran Wi-Fi stability tests before flashing GrapheneOS onto it, and had only one wifi drop. I turned off the "Adaptive Connectivity" in the original OS and that solved that issue. However, after flashing GrapheneOS onto this brand new from amazon pixel 8a, the exact same Wi-Fi dropping issue is there.
At this point, I believe it is safe to say that the issue is not my home wireless network, but an issue with the OS not having the option to disable "Adaptive Connectivity."
Any further advise and assistance is welcome.
