[SOLVED] why ip addr & nmcli output result 30 over seconds later on a live iso

andrewysk · 01-08-2022, 05:09 AM

Recently i have mpv problem after updated manjaro kde.
Now MPV just doesn't work anymore even after several times of reboot.
I even force uninstall mplayer, mpv and smplayer the reinstall mpv to no fix.
Hence i try to run manjaro live os that i have burnt into usb stick (1 year ago), to install mpv on the live os to see if it works.
Successfully installed MPV from remote depo.
However i put the system to "sleep" when i left the system.

After wake up , the desktop has got no more ethernet connection to internet. **i have experienced this WOL issue on this distro before, i know this bug exist.
However i forgot how to fix it.

I wanted to try out these 2 originally available network tool on the system:
$ ip addr
and
$nmcli
I found out the

Code:

ip addr

command too forever to output result, it just hanging there chilling.

and with

Code:

nmcli

tool, it took around 30secs to 1 minute to give output.

Anybody know why does it takes so long to produce any output (if any output at all) ?

I would like to know the reason behind all these..
and hopefully able to enable the network connection so that i can continue to use it to find some info while troubleshoot mpv.

ps: I wonder is it again have to do with IP6 issue that causing the nmcli and ip tool behave so bad ?

Thx

By the way "inxi -N" shows that i have 2 ethernet device. I am sure they are all functioning physically.
*i wouldnt' type the output here, because the pc involve has got no internet connectivity..

What I have seen here implies that this may be a problem with letting the system sleep or suspend. I seem to recall that others have solved it by never sleeping but instead doing a full shutdown and a clean restart.

While I don't use manjaro I would suggest you try this workaround and see if it helps.

I expect the long hang with ip and nmcli is due to the state of the ethernet cards.

Thanks for your opinion, That's all i need.
Thanks.

Do you know where i can find the whole list of ethernet driver ? I have read some old similar issue with suspend, and someone responded the driver is not uptodate.. hence i would like to know where they know what is the lastest driver ? .. is there a website to it ?

Code:

https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-usb-3-0-software

the only version is: r8152 (r8152.53.56-2.15.0.tar.bz2)

while the ethernet driver mentioned in the post was never than that posted on official website realtek :
r8169

Thanks

You can do 'lspci -nn' and look for the adapter there. There should be a part formed like [xxxx:yyyy] and that would be the actual chipset ID for that adapter. Using the value inside the [] will allow you to search for the exact driver.

Some of the newer ethernet cards (of all brands) do not work well with the older drivers and that may be a factor.

Thanks @computersavvy for the good info.

BTW, I just realized that the original question was about network issues after sleeping or suspending when booted from live iso.

Since all configs for the live iso are done and stored in memory it seems likely that a wakeup after sleeping may not properly restored / reconfigure everything. It may also be the reason for the network slowdowns noted since the drivers on the installed system may have been updated from the repo but booting from the iso gives older versions of software than may be in the repos.

Ya, the issue is after sleep.
The rest (about driver) i have no idea, since i wasn't able to upgrade the system. .
As for older version of driver that causes slow in respond.. that should be it.. because it was running totally fine when just started up.. it only happens like that after wake up from sleep.. When i tried $lspci -nn , it also never respond me but just kind of keep waiting for output.

However, since i didn't manage make a brand new live iso to work for testing out mpv player issue (which the whole purpose of the test is to test out if mpv also have problem on the brand new live iso, or it just have problem on my current upgraded desktop) , hence i gave up messing around with it..
I even got a cold pour of water from Manjaro team, they harshly responded me for messing around with live iso as pointless, and even unlisted my thread. lol
