wifi connection issues

mat1024

Hi all,

My Pixel 7 Pro has stopped connecting to my home WiFi since Nov 25.

information
Pixel 7 Pro
GrapheneOS TD1A.221105.001.2022112500
Netgear AX12 RAX120 Firmware V1.2.8.40, WPA3 Personal

error messages
"Can't connect. Try again later.""

(a) the phone used to connect to my home wifi without any issue before nov 25

(b) already tried to reset all connection settings, reset the router, reboot the phone, used different MAC settings (peer etc.), change to password with no special characters, connect to WPA/WPA2 2.4Ghz wifi

(c) the phone connects to public unsecure network, to my office network (but no internet available), used to connect to my secure laptop hotspot but not anymore

(d) all my other non grapheneos devices connect flawlessly to all networks

Please help.

Might not be related but check if Private DNS is disabled (Settings - Network and Interner - Private DNS).

Also check your routers DHCP IP pool config (maybe there are no free IPs available for your device, especially if its set to use randomised MAC on each connection), also check if there are no specific rules for your device on your router. Also try to reboot your router to clear DHCP lease pool.

I can second this - nothing in my home setup of wifi has changed, the only thing changed was installing an update for GrapheneOS and rebooting and ever since then, my home wifi is not abnle to connect any more.

My Pixel 6 tries and then after a few seconds gives back the message: ip-configuration issue ("IP- Konfigurationsfehler", since I am located in Germany).

Like OP, all other devices in our household remain functionable, also: I have not actively changed or tempered with any settings whatsoever and also not the slightest issue with wifi connections before (using GrapheneOS with this particular device for almost 3 months now!

Open for suggestions where to look - and mostly: to look for what exactly, since I cannot figure out what has changed.

These connection problems remain. I am on TD1A.221105.001.2022120300.

Go to settings - privacy settings - permission click network than click on three dots in right corner and display systems apps and make sure that you haven't declined network access to something that you shouldn't have.

Also your router should keep log, check if you find something there.
I would test creating a new separate network on your router and test if I could connect there. This could help you find out if you should search a problem in your network settings or innyour phone's settings.

Thanks, I have done / checked all that already. There is nothing wrong with my home router, it used to work before Nov 25. Even my old kindles can connect to my wifi.

What does it mean you checked everything?
All system app have network permissions allowed? You think or you really checked? Did you also checked your routers log? Do you see there your device connected and what does it says when it disconnected? Did you try creating new network and connect there? Does it behave the same way or not?

As your issue is isolated and doesn't affect other users, the issue is on your side. I would guess you denied some system app's network permissions.
It is easy to say that something doesn't work.

Also the only way I can sustain a connection more than like 24h, including carrier data, is to reset all internet, blutooth etc. settings and re-add the networks every day. This situation is immensely frustrating.

Where did you read that I "checked everything"?
I already did all the steps described above, it is in the first post.
I cannot connect the phone to the router, while everything else can that's my main issue, first post also mentions I am on my laptop hotspot.
And yes, all system apps have network permissions allowed.
Reading and guessing surely aren't your strong points.

Would you say that based on what you previously wrote it is absolutely clear that you cannot connect to your router at all? Nevermind...

Tact and courtesy toward the people who try to help you would be a better way to achieve what you want than to attack people who try to help you.

I want to make it clear that everybody posting on our forum, or our community in general needs to be kind and understanding.

I understand that things can get heated, especially when you're dealing with an issue that seems especially perplexing, but I will not tolerate any kind of arguments or bad faith back and forth in the community. Please be nice to each other, or simply stop engaging with one another.

@mat1024 Sorry to hear your experiencing issues. This isn't really something that we've heard from the community in general, so I don't have an immediate solution in mind. It's especially confusing that this also happens with carrier data.

Before we assume hardware issues, I'd like to exhaust every other possibility. It may be very bothersome to do so, but would you be willing to factory reset your device and see if that makes a difference?

If you're okay with doing that, I would recommend not installing or changing any settings. Simply factory reset the phone and see if you have the same issue again.

The next step would see if you can reproduce this on Stock OS as well, which would lead me to believe this either has to do with an AOSP bug affecting both Stock OS and GrapheneOS, or that it is a hardware issue.

HI Matchbox,
Sure! I'll try that and let you know.

mat1024

Phone reset to factory default. Tried to add the wifi on startup. It did not fix the issue. I get the same error message. Are you saying I have to revert to AOSP? Do you have any reliable guide for that?

mat1024

I am following this guide:
https://developers.google.com/android/ota
Failed to reinstall...

mat1024

(cannot remove the non-stock key: error device not found)

mat1024

Well I get the same error on AOSP. Must be a hardware failure. Thanks for the help.

mat1024

I cannot f****** believe it. I went to Google Help, and they advise not to hide networks. I enabled SSID broadcast and AOSP is connecting to my home WiFi now. In case it can help anyone..
Reflashing GrapheneOS.

Well, that is quite crucial information which you forgot to mention that you tried to use hidden network, but it's fine that you found the cause for your issue.

That Google help advice is not complete, because you can actually use hidden networks easily.

When you are adding your new WiFi network's credentials, there is an option below Advanced settings, there you have to explicitly choose hidden network. With this enabled the connection works. That doesn't explain, why it simply stopped working, if you were able to connect to the same network before, but if you need or want your SSID hidden, it is a solution. Happy WiFiying:-)
