Internet Connection down after first update

ShalokShalom · April 21, 2025, 5:36pm

I installed the Mocca ISO, and in both the live mode and at the initial boot, it supported an internet connection.

I had my phone connected via USB tethering.
I updated, and once the update was done, I rebooted.

After the reboot, I wanted to do the pacdiff merge, since the welcome app suggested me to do it.

I tried, but I received no promised merge application. After I inputted my password, just nothing happened. So I opened the Terminal via the button on the top of Radi, and it said I had no internet. Low and behold, I had no active connection.

Checked the phone, all was fine. Added an external Wifi dongle, the network widget wouldn’t recognize it.

I restarted NetworkManager by hand, nothing.

OK, lets look into the pacman log. The entire /var/log is empty. What?

I have a perfectly running Garuda (Dragonite) running on my laptop, nothing like that happened.

(I was also not promted to merge some pacdiff there, but this shouldn’t matter)

Due to a mistake of myself, we have no snapshot anymore as I booted into the second oldest, to see if that is recent enough to re-establish the connection (there were three entries) and somehow came to the decision, to save that snapshot before making sure the internet is really back.

I forgot that this resets all the snapshots, as this is now the only remaining one (somehow weird decision to delete all other snapshots then, I could swear that wasn’t the case previously)

Let me upload the logs and inxi that I have, I used journalctl -b -r and garuda-inxi.

Sadly, there is no pacman log, as mentioned.

From the topic template:

After rebooting, post the FULL output of garuda-inxi in the body of the post (not linked externally, or collapsed with the “hide details” feature)

Format terminal output (including your garuda-inxi) as a code block by clicking the preformatted text button (</>), or put three tildes (~) above and below the text

I’ve fixed it for you.

ShalokShalom · April 21, 2025, 7:19pm

I reinstalled the system. Could reproduce. I suspect something with the kernel or network stack. Since the device is already quite old, I doubt its something on the driver level, personally.

I will use NixOS and see if its the same.
Thanks for the help so far.

Edit: NixOS doesn’t bother to come up with working internet even in live mode.
I tried the current 2024.11 ISO, and that puzzles me, since Broadwing was released after that. (There is currently no way to see the release date, since the Blog is down, but I remember it was just a month ago, or so)

So if the NixOS release from November 2024 does have this issue, the March release from Garuda does not, and some update after that (re)introduces it - I dont know what to say. ^^

Also, it seems the WiFi dongle is not even recognized by lsusb, so maybe its broken. (Its lights are on, but that does not mean its good)

That means, maybe its something in the stack, that handles the usb tethering (I know nothing about that) so I am going to try to find a way to connect this machine by some other means to the internet.

nepti · April 21, 2025, 7:44pm

In this case it is always recommended to test another kernel first - for example linux-lts + linux-lts-headers.

ShalokShalom · April 21, 2025, 7:51pm

Yes, true. Now I just need to find a way to do that without internet.

Will move the files from the other computer or get the internet running somehow else.

Issues like these are the worst, since you are so limited with bug tracking due to the very issue itself. Alone moving the logs from the computer to my main machine in order to upload them, was a pain. xD

Thanks for helping

nepti · April 21, 2025, 8:10pm

Since the issue obviously only occurs after the first system update, install Garuda Linux and simply do not perform a system update. Instead, install the linux lts kernel:

sudo pacman -S linux-lts linux-lts-headers

Then reboot and select linux lts in the grub menu and boot with it. Then open the “Garuda Boot Options”, set the lts kernel as default under “Boot to”, click on Apply and Close.
Then run garuda-update, reboot and check if everything works without issues.

ShalokShalom · April 21, 2025, 8:45pm

I connected it via Ethernet to one of my access points, and it worked. Download the LTS now, but its safe to say its something with the USB or Wifi probably.

Edit: No success. Booting with LTS does not solve the issue.
Additionally, I plugged in another Wifi dongle, that does work on my main machine, and that one is also not showing up in the widget.

It does show up on lsusb, though.

The way the USB subsystem handles data packets is different. Ethernet uses MAC addresses and operates at layer 2, while USB tethering would encapsulate network traffic within USB packets, handled by the appropriate kernel modules.

Since the device itself is recognized (both the phone and the second WiFi dongle) I assume its about the way USB internet is handled.

Afaik, it could be about some USB powersave mode, maybe? I could play with sysfs or tlp to see, although I am fine with using an Ethernet from my access point for now.

Afaik, USB network stuff creates its own virtual interface, while ethernet works right on a physical port.

Try the suggestions below:

Disconnect any network devices other than the wifi adapter you wish to get working properly.. This includes LAN Ethernet cables, USB to Ethernet adapters, other USB wifi dongles, and USB phone tethering. Disconnect any USB peripherals connected to the computer such as powered USB hubs.

Then, power down the computer and remove the power plug from the PSU or the wall power socket. Let the computer sit without power for a few minutes. Then, hold down the power button for approximately 30 seconds. Pressing and holding the power button will drain any residual power from the computer’s motherboard, which can often help fix strange hardware issues.

After that procedure is complete, reattach the AC power cord and restart the computer. After rebooting, hopefully your wifi adapter will be working properly. If not follow the instructions below.

Resetting the BIOS back to the factory default settings sometimes helps to get a troublesome wifi adapter working again. Boot into your BIOS utility and reset the BIOS back to the factory default settings. Save the default settings, and power down the computer. After the factory reset you will need to ensure the Linux compatibility bios settings are set correctly again. You will likely need to disable secure boot and fast boot, and be sure the sata controller is set to AHCI mode.

You may think those suggestions are unlikely to help, but that procedure often corrects many hardware issues.

Good luck.
