[Bug] Connection to the wifi network sometimes failed without reasons

lark582

Hello,

I was able to successfully connect to my Wi-Fi access point with the
default ROM on my Pixel 8, but once I installed GrapheneOS, the Wi-Fi
started malfunctioning and sometimes I can't connect; I have to try
several times.

I don't have this problem on my other devices either.

I don't have any other Wi-Fi networks on the same channel, and I use 5
GHz Wi-Fi with WPA2/3.

I have already tried to reset the phone again, without success.

Would anyone have any idea where the problem is coming from please? I contacted the support by email, but I was sent back here.

Hello! Sounds like you're able to adjust the AP/router. Try turning off a few to all of these, then connect. If successful, narrow down the issue by reverting some changes.

Most of these are only for mesh networks. (Many, collaborative wifi stations)

First do any updates on your wifi router!

turn-off/disable
802.11r - fast bss transition or FT roamign
802.11w - protected management frames or PMF/MFP
802.11k - radio resource management or RRM
802.11v - BSS transition management
Switch to WPA2 ONLY

The fix is likely 1 or a few things above. You could also try:
Disable wifi 7 and/or 6 (force wifi 5, 4)

You can try on your phone:
settings > system > reset > reset wifi and bluetooth
This'll also make it forget your saved wifi passwords and bluetooth devices.

Let me know how it goes.

It could be your phone is compatible with whatever you changed but your router has a broken implementation of it.

Could be a hardware issue since your phone should be new enough to be compatible with somewhat not recent wifi technologies.

Might be your router behaves poorly when dealing with MAC address randomization. First thing to try is changing from "Use per-connection randomized MAC (default)" to "Use per-network randomized MAC" as described in the link below.

What surprises me is that I'm having this problem on other Wi-Fi networks, and that wasn't the case before :/

I don't have these settings:
802.11r - Fast BSS Transition (FT-Roaming)
802.11w - Protected Management Frames (PMF/MFP)
802.11k - Radio Resource Management (RRM)
802.11v - BSS Transition Management

I’ve also already tried disabling Wi-Fi 6 and 7.

I’m not sure about trying WPA 2 only, so I’ll stick with what I have.

But thanks

This is the WPA3 that does not work properly at all with GrapheneOS.

Thank you for the help, especially Johnnyloans

No, unfortunately, I've already changed that too, and it didn't make any difference—it happens on every Wi-Fi network.

Sometimes when I tap a Wi-Fi network a few times, it completely cuts off my Wi-Fi; the button on my phone switches everything off by itself.

😭

But thanks

lark582 it happens on every Wi-Fi network.

Try flashing GOS again.

Or this could mean your phone has a hardware issue. Return/warranty it or use stock OS.

Also, there is no technical support email for GOS

I had the same problem and I suspected GOS for this. But later I found that there were several misconfigurations in my DNS and IP routing settings. I managed to fix that with the help of AI.

Have you tested that both IPv4 and IPv6 route correctly and both protocols resolve hostnames and IPs?

I don't have any problems on my other devices and I didn't have any before installing GOS so I think it's weird.

Johnnyloans

Do you have developer options enabled or changed settings inside of there?

lark582

Johnnyloans

Developer options are disabled

lark582 That, probably is not it, but anyway - is your system datetime set properly? After my phone is kept off for a while and upon boot it doesn't get datetime update, I can't connect to wifi.

lark582

mmobder Yes my system datetime is correct
