How do I disable and then re-enable network card?

[MlxySF]

Hi there everyone, I'm new to Linux and wonder if there is Plug N Play commands like on Windows available on Linux. Currently, I can't dig any information on the internet unless for lshw, udev and much more. The commands I need is the below :

pnputils /disable-device {device id}
and /enable-device

These are the command on Windows, wonder if anyone have a solution to have a similiar or run these on linux. Thanks in advance!

I guess you mean pnputil, not pnputils. This tool: https://docs.microsoft.com/en-us/window ... and-syntax

I don't think there is a single command that is equivalent for all device types. Perhaps instead start with specifically what device you want to disable and why?

I wanna disable my network card and re-enable it. It's because my PC is kinda weird with the internal network cards. In Windows, I have to disable and enable it using the commands I stated in the ori post in order for the network card to be able to connect to internet and be used without any issues. Without disable and enabling it, network card will have issues in Windows, and also Linux of course.

And yea its the pnputil.exe in windows which have the command that I stated above.

Also, a thing to mention is that the network card will boot as "The device is not working" and therefore there is no logical names to do sudo ifconfig name up.

Rather trying try to find an equivalent to your Windows bodge, it would be better to fully describe your problem in order to get a proper fix.

If the NIC shows in lspci as e.g.

Code: Select all

[ ... ]
00:19.0 Ethernet controller: Intel Corporation 82567LM-3 Gigabit Network Connection (rev 02)
[ ... ]

you can try

Code: Select all

sudo sh -c 'echo -n 1 >/sys/bus/pci/devices/0000:00:19.0/reset'

or maybe

Code: Select all

sudo sh -c 'echo -n 1 >/sys/bus/pci/devices/0000:00:19.0/rescan'

If need be,

Code: Select all

sudo sh -c 'echo -n 1 >/sys/bus/pci/devices/0000:00:19.0/remove && sleep 1 && echo -n 1 >/sys/bus/pci/rescan'

Supposedly at least of one those does what Windows' PNPUTIL does.

Could OP just use ip(8) to enable and disable the network interfaces? IE: ip link set IFACE [up|down]

[rene]

No; see just above me; there's seemingly nothing to ip up/down. I assume it's a matter of a firmware reload trigger and that might point to possible better solutions such as resetting the card from the initramfs so that the later module load finds it in consistent state -- but if it's not working on Windows either, whatever I guess, at least for now.

Have no luck on trying all the above, my network card is bcm4359 which is using the firmware-b43-installer. Whenever I boot, network card will either be disabled and wifi internet connections cannot be turned on, or the card works and it can find internet connections, but it will be stucked at connecting when prompt to be connected and coming out lots of internet password request, and then the network card will went down and can't enable wifi anymore.

This issue also happens in Windows but a different situations. In windows, it will boot fine or sometimes marked as problematic, and after internet connected after a few mins of usage it will disconnect from the internet and the network card cannot connect to WiFi anymore. But this problems are all fixed by everytime I boot like I said I created a bat file with the first post commands to disable and enable the network card and it works well without any issue till the next reboot.

Wonder if anybody had any similiar problems and have any other possible solutions? Thanks!

So as to give people google fodder you will want to post output of inxi -Fxz.

These are the results from inxi -Fxz

Note that you can just mouse-select the text in a terminal window, rclick-copy and rclick-paste into a reply box such as here on the forum; preferably in between [code ]...[/code] tags (also available from the </> button above the reply box when you are replying) so as to retain formatting.

Any case; am not finding similar issue for your Lenovo G460 with BCM43228. Your v2.15 BIOS version appears latest -- but it's a system from circa 2010 and with specifically troublesome closed/proprietary Broadcom WiFi. I believe you can try to run

Code: Select all

sudo apt-get install bcmwl-kernel-source

which will install a driver, and then reboot to see. If not I'll need to excuse myself from the thread; am not a mobile tech person, and this system is getting to be too old to have many relevant google results around even if they exist.

[MlxySF]

I tried installing drivers too, but doesn't fix the problems. It might not be driver issues but others which I'm not sure. As in Windows, just a simple disabling and enabling the device back again fix the problem. On Linux, I can't find anything to enable and disabling the driver unfortunately, bad for me as I really wanna try out Linux mint

[rene]

Have you tried the exact apt-get command (and reboot) I suggested?

Otherwise; my above advised echoing into sysfs should disable/enable, certainly the last remove/rescan. No other suggestions I'm afraid...

Yup I have tried the apt-get install bcmwl-kernel-source command and sudo reboot. But didn't work

Also sometimes the echoing commands works, it does disabled the network card, but then I can't enable it anymore for some reason. Well, I guess I have to abandon the toughts of using Linux on this old machine and stick with Windows 10 then

[rene]

Well; it's supposedly at least somewhat Broadcom specific, so I guess it might be worth a shot to see if the board's expert on those matters feels anything worth mentioning; he'll get pinged by the below quote. I myself am as said not a mobile tech person.

Just so as to doubly note for his potential sake, in case it needs to be undone again for the sake of further tries: bcmwl-kernel-source has been installed, i.e., the driver DKMS-ed.

[sleeper12]

Try:

Code: Select all

sudo apt remove firmware-b43-installer && sudo apt install --reinstall bcmwl-kernel-source

Reboot

Also post what this shows:

Code: Select all

iwconfig

Hi there sorry for the late reply, tried the command too and still not working. Have uninstalled Linux Mint, but I'm always interested in testing and moving over from Windows, just need the WiFi thingy to be fixed like on Windows.

Just an off topic right here, maybe anyone knows whats the problem of my Mini PCI-E slot is or any other things that may be related to cause this network card issue? I bought another Intel Mini PCI-E network card too, and also it's the same problem on Windows and I have to disable and enable using the commands in the bat file everytime I boot up.

Thanks in advance!
