Network Manager

Hi there…

From this location I connect to the internet using a usb stick (mobile broadband: 3g). When attempt to use EndeavourOS the led’s on the stick light up as usual, showing I am connected at the basic level. I use NetworkManager to set up a new connection. then I save the settings. When I re-open the settings manager, the settings I have used are remembered. However, nothing I do prompts the Network Manager to actually make a broadband connection and my settings check shows nothing for broardband. I am able to send this plea because in another partition of my hard drive I have set up LinuxMint and the same modem/mobile broardband works perfectly.

It has been suggested that I need to uninstall/reinstall NetworkManager. What do you think of this suggestion? At home the internal wifi setup on this laptop works 100%.

riccardo - some additional information: my usb modem is a Telstra approved modem and is mentioned in the output of the ‘lsusb’ command, the laptop is a Compaq model which I carry about while I am on holiday, & I have tried putting the modem in before starting and after everything is ready. Nothing seems to work!

I don’t have any direct experience with mobile broadband USB modems, but have you checked the Arch Wiki page on the subject, especially the section on Network manager? There’s a lot of info there re: what you need installed and running.

:australia: :kangaroo: :koala:

Maybe you should check that ModemManager is running:

systemctl status ModemManager

If it is not running correctly be sure to post the output.

Thanks tbg for your thoughtful comment. I immediately thought: if systemctl status ModemManager is NOT working, would I expect to have difficulties with my wired contact thru eth0 at home, and also my wifi contact through wifi … when using my local wifi (router)???

However, when I am back home in about 24 hours I will do as you ask and post the result.

ModemManager is used/needed only for mobile broadband devices.

Yes, I was thinking that was what he was using.

Apparently, he’s not from his last post.

Confusion on my part.

He is trying to use a mobile broadband USB dongle; I think he was just wondering why, if the ModemManager service isn’t enabled/working, he could still connect via ethernet and wifi. I was just letting him know that ModemManager is only necessary for mobile broadband devices, i.e., it’s not needed for ethernet and wifi. :wink:

Ay yes, not enough coffee with the heat here. Not at my best. :sleepy:

Oh please, you have forgotten more about networking then some people know :slightly_smiling_face:

Greetings everybody

Thanks for your help. I am back on my desktop a.d have the laptop setup in the next room. I did a complete re-install of EOS and (unsurprisingly) the problem remains: although the mobile broadband modem works perfectly, it is not seen by my laptop. In reply to the suggestion above I issued the command : ‘Systemctl status ModemManager’ and in response I got;: ‘Unit Modemmanager.service could not be found’. Are we onto something here??
How do I go about installing ModemManager??

…is rarely the solution, for nixes.

What do you get with these commands?

If you genuinely need it & genuinely don’t have it, to install:

sudo pacman -S modemmanager

Thanks for your help. I am getting increasingly frustrated by EOS’s quirks! I tried to run the suggested pacman command … very logical. Unfortunately, my machine decided it had to upload all the changes since the release of the iso. This it could not do because my connection to the internet was via mobile b/band. Talk about Catch-22!! Then the booting stopped working … and the machine froze about 20 sec into the process! What a tail of woe!! I install another linux … which just works for me. I shall return to EOS on another machine… probably on old desktop with an eth1 connection to my router. Thanks for all the help people.

riccardo

Maybe a fixed-release distro might be more suitable for you. Rolling distros tend to… roll.

Final Reply…

Thanks to ALL who have contributed to this issue. After some reflection and a try of a couple of other distros, I bit the bullet and installed Manjaro [Gnome] today. It just did what I wanted and I am able to connect and use three different forms of internet connect viz. ethernet, wifi and mobile broadband. It is from the same family, but set out a little differently to EOS. I am enjoying the learning experience!

Thanks again everybody!

riccardo

Instead of just enabling ModemManager.service, you installed a distro that has ModemManager enabled by default.

Talk about taking the long way around.
