wifi connection issues

breathless19

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.

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?

Hi all,
I realize I'm a little late to the party here.

TL;DR:

Check if DHCP Auto Reservation is enabled in your router.
If so, disable it.
Then, on your GrapheneOS device, change the network setting under Internet -> [your network name] -> Privacy to "Use per-network randomized MAC"

I too was having this problem, specifically not being able to connect to my home network and receiving the "failed to obtain IP Address" message. In addition, my father's roku was also having trouble connecting.

Since other devices on my home network were still connected but the Roku was having a similar problem, I too thought it was a DHCP issue.
I rebooted my router ... no change. Saw my DHCP lease time was 4 hours and there were 200 IP's available by default so I too didn't think I'd be hitting that upper limit.
However, there was a separate section in my router's GUI for DHCP reservation and a toggle for DHCP Auto Reservation which was toggled on (which apparently associates the same IP to a device's MAC address on first connection). Under it was a huge list of MAC addresses and associated IPs.
Since I have multiple access points in my house and manually change between them and my phone was set to "use randomized MAC on each connection" I guess I filled this table of reservations as I moved throughout the house.

So after toggling DHCP Auto Reservation off and setting my phone to "Use per-network randomized MAC" for my home access points, I received an ip address right away and connected no problem.

Since disabling DHCP Auto Reservation cleared the table of saved IPs and MAC addreess entries, I reenabled it since I think majority of the excess entries were when my phone was set to use a randomized MAC on each connection.

Hope this helps.

MadeThisAccnt4DisQuestion Hi. I haven't checked your solution with my home router yet, as I'm out of town. I'll do that once I'm back.

In the meantime, I'd like to ask about other cases of this issue. I need to have access to LTE or 5G on my daily routine, and I'm getting this error both on those and on work WiFi. The thing is that this only happens on my Owner account, and not on the user I'm on for most of my daily tasks. However, that means I don't have access to all network settings, as those are only available on the Owner's side.

Basically, my Owner is deprived of a connection (no Vanadium, no app stores, no app installs), and my daily user is deprived of network settings. This has been happening since the last update.

Any possible solutions would be much appreciated.

Are any VPNs, ad blockers, or content filters installed? If so, try deleting all of them, from all user profiles.

davidnarok

de0u Only Orbot on Owner profile. I tried simply turning it off but it doesn't make a difference. If anything, there are apps that show me a connection error with VPN off but they don't when full device VPN on Orbot is on. Still, they don't manage to actually go online.

As far as I understand it, it's recommended to use Orbot so that all app store traffic goes through Tor. Of course, I'm willing to try your solution, but would it be viable to avoid using VPNs permanently if I'm privacy-focused?

Thanks for your reply!

davidnarok As far as I understand it, it's recommended to use Orbot so that all app store traffic goes through Tor.

"It's recommended" doesn't say who is doing the recommending. There is a fair amount of discussion of Orbot on this forum, hardly all positive, such as: https://discuss.grapheneos.org/d/19391-why-is-orbot-so-unstable

If apps in the owner profile are having networking problems and Orbot is installed in the owner profile, there might be a relationship.

davidnarok Would it be viable to avoid using VPNs permanently if I'm privacy-focused?

Some VPNs work better than others.

davidnarok

That's a good

de0u yeah, that's a good point. And the thread you linked actually shed some much needed light on the subject of Orbot.

Thanks for the help. I'll try ditching Orbot and finding an alternative.

davidnarok

Back with an update.

Disabling Orbot worked. But after a few days, my LTE connection stopped working on my Owner profile, which I need for certain uses I make of it. Also, my phone number is not showing up in the settings.

I had previously followed the instructions posted by other users on this thread. I don't know what to tweak anymore.
