Hello,
I seem to have an issue with the network connection:
After downloading large files (and stressing the network connection a bit) it just stops working.
Network manager doesn’t seem to crash, the symbol is still there, one can view the connection details etc but there is absolutely no data flow. I assume it just freezes in the background.
So I did:
tracepath 192.169.0.3
Which retured:
1: sent failed
Resume pmtu 65535
Then one after the other: systemctl restart systemdateien-networkd... sudo service network-manager restart .... sudo systemctl restart NetworkManager.service (which pops up a window telling me I‘m disconnected).
ifconfig
returns:
inet 127.0.0.1 netmask 255.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1 (Local Loopback)
RX packets 4693 bytes 1124018 (1.1MB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 4693 bytes 1124018 (1.1MB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
In the end there is no (known) way to restore the WiFi connection without a full reboot.
Very annoying! Has anyone else experienced this (and maybe even found a solution)?

What is the WiFi adapter hardware?
In order to exclude a hardware problem, I'd recommend live booting another distro (preferably one using a different code base) and see if the problem persists.

To answer your question, I did a lshw.This returned (amongst other things):
*-pci:0 […]
*-network DISABLED
description: Wireless Interface
product: PRO/Wireless 3945ABG [Golan] Network Connection
vendor: Intel Corporation
…..
So something disabled it. It should suddenly be disabled.
So I did a complete reboot of the machine and the DISABLED label went, everything else is the same.
But which is the service / module that needs restarting?
I cannot keep rebooting the machine as I sometimes have unsaved work on it which needs to go to a remote location first before I shut down.

I think Intel devices are usually supported in linux kernel itself, so probably your driver is okay...
I personally am not familiar with the services/etc so can't help there, but I did see in another thread where kiezel posted a link suggesting disabling network adapter power management. Perhaps its relevant to you, can't hurt to try.
Did you ever check if other distros have similar issue?

Also worth a try if you haven’t already is check it’s not disabled via the Fn key or switch somewhere. I know it sounds patronising, but I have actually spent time troubleshooting wireless stuff and it was that all along.

Thanks for the hints. Got something to read and check now.
No worries about the Fn key. Yes, these things can drive you crazy and I expect something simple to be behind it actually.
I do have a suspicion that the WiFi module gets disabled due to overloading or so, since this occurred when I was importing a large file while at the same time working on a spreadsheet and saving it remotely.
As for other distros: Had Mandriva and Mint on this machine before and it never happened.

Update:
I got kicked out of the WiFi module again, this time w.o a big file download/upload.
lshw always shows the wireless as „DISABLED“
sudo rfkill list however does not show wireless lan as soft or hard blocked.
So I am assuming a kernel module was kicked out I will need to analyse the lsmod output a bit further
iwl3945 appears to be the driver.
It is listed under lsmod output, nothing I can identify there 🤔
So IF it has to do with the kernel module, how can I restart it?
