Wakeup networking issue

whismerhill · 28 February 2020 20:35

Hi,
the problem:
-upon wakeup the network interface says "cable disconnected" (it is not)
and there is no more network communication.
-Physically the Gigabit switch, has a yellow light indicating a 100Mbps link (which is expected) and the powerlines are fine as well (all green lights)
-rebooting fixes the problem until next sleep

So I'm pretty sure it's a software issue.

Me: I can take terminal commands, but I'm a manjaro newbie, (not a complete computer newbie). I already fixed some manjaro pacman issues with the help of the wiki for example.

I don't really know where to start that troubleshooting
I tried searching but none of what I found seemed similar enough (but maybe I searched badly) or involved deep modifications I wasn't really comfortable with.

Thanks for any help

Welcome to Manjaro!

Concerning this:

could you elaborate on the bold text below?

whismerhill:

Physically the Gigabit switch, has a yellow light indicating a 100Mbps link (which is expected) and the powerlines are fine as well (all green lights)
Are you a Windows power user or a Linux user? (I.E. have you tried restarting the NetworkManager instead of rebooting? If not: try that and what does that do?) because of this:

whismerhill:

I can take terminal commands, but I'm a manjaro newbie, (not a complete computer newbie).

whismerhill:

-rebooting fixes the problem until next sleep

(No offence intended, just trying to find out how detailed I need to be in my responses)

P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you're using, which CPU/GPU you have, ...

whismerhill · 29 February 2020 22:04

First no offence taken, I understand perfectly
so yeah kind of a windows poweruser
heck I have worked as a windows helpdesk for a while so I know the drill...

On my network I have a router which is connected to internet, from this router a powerline is connected which converts the network signal to make it transit through regular house power cables, then another powerline, then a switch, then this laptop.
In any case, I'm not sure why I started talking about that since it doesn't really matter.
if a powerline is down, it wouldn't show "cable disconnected", but instead "cable connected but no internet connection" or something akin to that. (because of the switch in between the two)
I tried systemctl restart NetworkManager.service which AFAIK should do what you asked. no changes.
I'm not sure if there should be log files, but at least the command terminal shows nothing.
it still says the network cable is disconnected (which again is not)

Fabby · 29 February 2020 23:14

Thanks. Some people are more susceptible to perceived insults than others.
That's exactly what I wanted to know: Thank you and that explains 100Mb, because 1Gb over power-line adapters is unfeasible.
Drat! Not what I expected.
I don't know if XFCE has an "airplane mode" (I'm on KDE) but what happens if you turn that on and off?

Why all these stupid questions?

Well, if we find a way of turning the network connection back on again without rebooting, we can script it and put it in the wake-up script and then your problems are gone...

whismerhill · 1 March 2020 00:03

100Mb is actually the max link speed of this network adapter of this crap laptop I currently use (due to a motherboard failure on main system but that's another story)

It's just the link speed to the switch, it could be 1Gb even if powerlines couldn't handle that amount of data throughput afterward. (there's another 2 computers on this switch)
And to be complete on this matter, my powerlines actually do have a Gb link to whatever they are connected to as well. (D-Link DHP-P600AV)
the actual speed on the powerlines depends on the quality of the connection between all the powerlines though.And it doesn't max out the 1Gb link for sure

Anyways, I can't find any airplane modes,
I do have options to disable/enable network
and option to disable/enable wifi network
none of these do anything.

Just an idea, maybe if there was a way to restart the network card driver ?

I found this thread which sounds interesting but is aimed at another network card, so the solutions outlined seem to not apply to me. Not to mention complicated...

Fabby · 4 March 2020 12:45

In the script here, instead of enp2s0 use:

and instead of r8169, use:

(check your own inxi output to know why)

And don't worry about the blacklist note at the end: That doesn't apply to you (as you have different hardware and no conflict between different versions of the same adaptor)

cc @tbg Yet another issue _(probably) solved by your genius!

whismerhill · 1 March 2020 13:37

Soooo unfortunately .... it didn't work

I'll verify that I didn't make any mistakes while editing a bit later.
Pretty sure I didn't but you never know...

Thanks for the help anyway

Fabby · 1 March 2020 14:13

doesn't help us help you...

Please post your script, the relevant dmesg output, systemctl --list-unit-files, ...

and try this to see whether it provokes the same issue as going to sleep and coming back:

nmcli r all off; sleep 5; nmcli r all on

(also from the same thread)

whismerhill · 2 March 2020 11:04

so just a quick update
I haven't done all you asked because I ran into level of competence issues ....
still searching how to output terminal to file (and yeah I used to know that but I forgot, I'm ashamed of myself)
and honestly I am a bit busy these days...
however I tried this : No Ethernet Network Connection after Resume; very recent problem
and didn't even need to sleep/resume in between
So what it looks like so far :
0. Just waked up laptop, network connection is "unplugged"

sudo systemctl stop NetworkManager.service
sudo ip link set enp9s0 down
sudo modprobe -r sky2
Wait 5"
sudo modprobe sky2
sudo ip link set enp9s0 up
sudo systemctl start NetworkManager.service
Dance & whoop in joy as i see my network come back.
I don't know why though, it created a new connection that had IPv4 disabled
no matter I just enabled IPv4 and it worked fine
after comparing characteristics of the two wired connections (same MAC address & stuff, only graphical interface name was different, the new one having the name of the device "enp9s0")
I just deleted the original wired connection (e.g. not the newly created one)

Posting this, so I don't lose this text but I will come back and post more, I have a lot more diagnosis/testing to do yet

Fabby · 2 March 2020 12:45

That's good! So add commands 1-7 above to the script here and then your computer will wake up with a network connection automatically!

whismerhill · 4 March 2020 12:00

so two problems so far :

each time I do it manually it does create a brand new connection with IPv4 disabled
the services fail to execute properly

Weird... What are the contents of your NetworkManager.service? Something is there...

EDIT2: I was incorrect in here

and there were some updates that just came up ...

Fabby · 4 March 2020 12:19

I'm at a loss here: Did the upgrades solve your issue? or are you still having the issue? Or something else entirely?

whismerhill · 4 March 2020 12:42

alright so I was sightly wrong

the update came up
reboot
problem fixed (sleep, resume, network connection working)
disable the two services (that we created) and reboot
problem is back
re-enable the two services and reboot
problem fixed (sleep, resume, network connection working)

so the update (or one of the updates) seems to have fixed the errors I was getting with the services execution ? honestly I am a bit at a loss as well
additionally I'm not getting any new network connections creations so far.

Fabby · 4 March 2020 12:45

Good, so your original problem is fixed by the scripts. I'll mark that as a solution. Please open a new question for the new issue because this conversation is getting too long and everyone is going to be confused.
