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.

    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.

    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.

      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.

        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.

        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.

          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.

              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?

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

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

              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..

              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:-)

              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.

                13 days later

                Add me to the list too... Just got a "new" (refurbished) Pixel 6 Pro on Amazon.

                I just got the phone and had no issues with the stock OS. I played with the stock for about a half an hour on and off to make sure everything worked and so I could see what the stock OS was like compared to Graphene (I'm an iPhone user trying to switch). The phone had no issue maintaining wifi over this time (a total of several hours - but again, I only used it for a total of about a half hour, if that). Everything was working fine. I then installed GrapheneOS without issue - the brand new version that just came out yesterday. I literally did nothing with the OS besides change the wallpaper, install F-Droid and Aurora Store. No other apps whatsoever. After this I left it for a few hours unattended, came back, no wifi connection. Didn't change anything with my router settings, and all other devices in my house work fine. I did not monkey with any permissions / settings in the device. I simply cannot connect to my home network all of a sudden. I gave F-Droid / Aurora Store full permissions when installing - not that that should mean anything I don't think. Yes, I tried the mac address options for the network (per connection / per device / mac). It goes from "obtaining IP Address" to "Disconnected" (and I think I've also seen "failed to obtain IP Address") regardless of which of those settings I try.

                I've looked in my router and see nothing to be concerned about. I have under 50 DHCP leases, so its not like its bumping into an upper limit that I can see.

                Assuming there is actually some sort of DHCP limit that I'm bumping up against even though I'm under 50 devices, I think that the first time someone connects to a wifi network on GrapheneOS, there should be a short explanation of those three options and why someone may not want to use the "randomizing" thing at home. If this is all it takes for issues with many home routers to pop up, then its worth mentioning before someone fills up their DHCP allowance. Just my newbie opinion of course.

                Yes, I'm a networking idiot, but I do have 25 years or so PC tech / repair experience, so I should be able to figure this kind of thing out. The fact that I can't leads me to believe this is some sort of bug...

                It seems like rebooting my router with the "use device mac" setting enabled seems to have done the trick. Didn't work before rebooting the router. Hope this helps someone. If I have further wifi issues, I'll post back

                  breathless19 There's not really a reason to use the device MAC option. You could use the MAC per network instead of per-connection option instead.

                    I've since changed it to per network and haven't had any issues thus far, and no need to reboot router again.

                    3 months later

                    Can Confirm that going to Settings > Network and Internet > Internet > Click on your wifi "yourwifiname" > Privacy > "Use Per-network randomized Mac" or "Use Device Mac" will resolve the issue.

                    Though for privacy reasons I would recommend using the "Per-Network randomized mac" as both these options work just as well, it seems that some routers don't like the per connection randomized mac and this is what is causing the issue with network speeds being real slow or even network connections being denied.

                    I'm having the exact same issue. I've been trying to connect via ethernet. I did a factory reset and followed advice in this thread but still can't access any site via vanadium. I used to be able to access the internet on it but then one day recently it stopped. Maybe it's time to install android or get a new phone?

                      Ted It sounds as if something has gone quite wrong, but it's not immediately clear what. Can you give us more information about the situation before things went wrong and the situation now?

                      Before you ran into trouble, did Vanadium on your phone work using multiple Wi-Fi networks (e.g., your home and also some public/business networks) and also via cellular?

                      Now that you're having trouble, can you say more about what works and what doesn't? Do voice calls work? Text messages? Does Vanadium work over cellular data? What if you try two or three different Wi-Fi networks?
