Remaining connected while in sleep mode

depscribe

This is an unusual situation, but I doubt it's unique. Pixel 6a, up-to-date GrapheneOS. There is no cellular service where I live, and won't be until Elon's skymodem or whatever it is comes into service. This means that to keep from burning battery at home, I keep it in airplane mode with wifi on.

So far, so good. But after a period of time sleeping -- don't know how long -- it drops the wifi connection, so when I awaken it it goes through the whole connecting-to-vpn routine, then downloads every message that would have been there had it stayed connected, as it's supposed to. This also prevents it from receiving incoming calls, while with my carrier's wifi calling, calls should come through fine, as they do when it is awake.

I can't help but think there is an alchemic recipe of settings that keeps the wifi connection alive when it sleeps, as ut would cellular. Anybody know the secret handshake?

Thanks.

depscribe is it rebooting ? Do you have a short auto reboot time ? Only time I sew VPN reconnect is after reboot .

WiFi should stay connected while sleeping and auto connect if the connection is interrupted, see if you have it turned off

I didn't understand whether your Wifi connection is dropping or the internet connection behind it.

If the suggestions already given do not work - two ideas:

1) Have you activated a WiFi timer?
(settings> Network & internet>internet> Network preferences>turn off WiFi automatically)

If your WiFi connection is briefly disconnected at night, this setting may trigger the timer to automatically switch off your phone's WiFi.

2.) Have you configured a VPN kill switch?
(settings> Network & internet>VPN> always on VPN | block connections without VPN)

If your Internet connection is interrupted shortly this can lead to the VPN not reconnecting automatically even when the Internet connection is restored, depending on the configuration. If so, you should see internet disconnections in your router's error logs.
