Pi5 LAN connection issues

1

I’ve had this problem right from the beginning and have no ideas left on how to approach it.

For context: I’m usually the person that fixes your Windows problem, and I’ve already gone through numerous tips found on other forums (which unfortunately has been a while, so I can’t reiterate), but my experience with Linux is limited and I was mostly copying commands hoping I’d find a fix.

After booting, there’s a little popup at the top right telling me the Pi has an IP. It’s the IP I assigned to it via DHCP, and the Pi appears as connected in my Router, but the Pi has no access to the internet and I can’t ping any of my devices in the same network, and vice versa. The only “solution” I have is to reboot the Pi until it works (i.e. starts to inform about updates, too), which is silly and annoying.

It seems like there might be some services not starting properly. Also, whenever the Pi is not connecting, although it does appear in the Router’s menu, it’s not the same chain of icons as when it’s actually connected to the internet. (I’m aware that this isn’t very useful without screenshots, but I’ll deliver as soon as I can).

The Pi is not hindered by a firewall and I think it’s always using its physical MAC address. There is also no other device with the same IP around. It doesn’t matter whether I’m using WiFi or LAN, and it doesn’t matter whether I’m using DHCP or assign a fixed IP.

I’m hoping someone might’ve encountered this before and could give me an idea on how to further troubleshoot the issue :slightly_frowning_face: ?

Hi @verlakasalt,

I have been a Linux user practically since the beginning of this operating system.
Except for very specific cases where I am forced to use Windows, I use Linux for the vast majority of applications.

I think I can help you solve the problem.

We will probably have to exchange a lot of information. In order not to saturate the forum, if you think it is appropriate, send me a private message with your email and in this way we will have a more direct and fluid communication.

Regards

Not 100% sure it would resolve the issue, but worth trying.
Enable wait for network at boot in raspi-config.

@PM490 I don’t have that option in my raspi-config. But NetworkManager.wait-online.service says it’s active.

But since I booted the thing now…

This is how it appears in the router menu when the connection is only half-there.

Currently I can ping the Pi (IP and name), but the Pi can not ping my Windows PC or access the internet. SSH/VNC doesn’t work.

Now I rebooted, the Pi is online, pinging goes both ways, ssh works. My router says… the same as before :smiley:… I’m positive I had seen an extra icon when the Pi was online before, but I guess not today. So much for that.

Anyway. I’ve taken screenshots of the connection information window now. Maybe there’s a clue next time it doesn’t work.

@Manuel_Angel Will send a message. Thanks for the offer!

True, sorry I forgot that was changed in bookworm.
