Problems with Mobile Tethering

[hosadeeb]

Dear all,
Sometimes my ISP dies on me, and I try to connect through my mobile data connection. Now, the problem is: my Mageia 9 box declares the connection established, but no browser finds any address! I'm not using any proxy, so all my browsers are directly connected to the Internet. And when I checked, the tethered connection does have its own DNS servers.

I even tried connecting through the mobile's Hot Spot, still to no avail, although, again, the connection is declared established.

Strangest thing of all: using the same mobile and SIM card, when I use my laptop (instead of my Mageia desktop), the connection works just fine, whether I'm using tethering or the Hot Spot.

So, what I'm asking for here is: where should I look for the culprit? What could be that I'm doing wrong?

A million thanks in advance for your effort <3

You could try
https://wiki.mageia.org/en/Switching_to_networkmanager
as that works better for some.

Well, it would be helpful to know if you use net_applet (default MCC tool) or networkmanager to manage your network connections.
Also when you are tethered to your phone, some more details would be helpful in the case where it doesn't work

can you reach your default gateway? can ping any adress like 8.8.8.8 ?
what does your routing look like, what does your resolv.conf look like, and what does the browser show as exact error message?
what happens if you resolve any DNS entry?

Code: Select all

ip -o a
ip -o r
cat /etc/resolv.conf

I do have NetworkManager. And its applet is indeed the one XFCE has.

Still, when I try

Code: Select all

sudo systemctl enable --now Networkmanager.service

I get an error:

Failed to enable unit: Unit file Networkmanager.service does not exist.

And, no: pinging doesn't work at all when tethered to the mobile. I believe I did mention this in my original post.

Well you have 2 default routes, that by itself is a problem because the system does not know where to send outgoing packets.
From the order of the routing table it first tries to send them over your your wired interface enp8s0 so that's why you cannot reach a DNS server nor anything else.

To configure your tethered hotspot as backup connection you'd have to write a script which needs to at least

Code: Select all

ifdown enp8s0

to remove IP and route for it.
Or you can switch to networkmanager, which you don't have currently as otherwise the error would not show that you posted.
Please read the wiki page that morgano linked.

[hosadeeb]

I did manually disconnect my wired connection! Still to no avail.

[doktor5000]

If by manually disconnecting you mean unplugging the cable, that will do nothing to the interface configuration nor your routing table for a statically configured connection.
See above, you need to actually ifdown the interface or you will have the same configuration as before.

[hosadeeb]

I meant, I used NetworkManager applet to "Disconnect" the wired interface. Isn't that enough?

[doktor5000]

Doesn't seem like it. Might help if you would explain some details about the two interfaces enp8s0 and enp1s0f0u10

And please post the output as regular user of

Well this is pretty clear - your mobile connection seems to be connected, but you have no network connectivity at all.
You need to check your mobile connection.

Please also post the output as root after disconnecting your wired connection:

Code: Select all

ps -ef | grep -i net
systemctl status NetworkManager -al -n 750


[hosadeeb]

I do have NetworkManager. And its applet is indeed the one XFCE has.

Still, when I try

Code: Select all

sudo systemctl enable --now Networkmanager.service

I get an error:

Failed to enable unit: Unit file Networkmanager.service does not exist.

And, no: pinging doesn't work at all when tethered to the mobile. I believe I did mention this in my original post.

That error I was getting, does it mean the functionality of NetworkManager is just not complete, or is somehow prevented?!

[isadora]

The mobile connection, on the mobile itself, works fine.

Code: Select all

sudo systemctl enable --now Networkmanager.service

I get an error:

Failed to enable unit: Unit file Networkmanager.service does not exist.

By reading the wiki link from the first comment you could have found that you have a spelling error in your command....

WRONG (yours):

Code: Select all

sudo systemctl enable --now Networkmanager.service

CORRECT:

Code: Select all

sudo systemctl enable --now NetworkManager.service

You do have systemd-networkd running, but this is disabled by default. Why did you enable it ?

Here's what it looks like by default on Mageia 9:

[doktor5000@Mageia9]─[20:04:48]─[~] sudo systemctl status systemd-networkd
○ systemd-networkd.service - Network Configuration

The mobile connection, on the mobile itself, works fine.

What does that mean in particular? The connection on your smartphone works fine, but you've never successfully used it on your PC with this setup?
Also as this seems to be based on some USB device, how do you tether to the phone exactly? Why not simply use a wireless hotspot for tethering ?

After activating your mobile connection your system changes from CONNECTED_GLOBAL to CONNECTED_LOCAL

The mobile connection, on the mobile itself, works fine.

You do have systemd-networkd running, but this is disabled by default. Why did you enable it ?

I honestly have never interfered with that! Maybe it was enabled in a previous installation. I mean, I've been upgrading the distro for many years, not installing it from scratch. If I do need to have it disabled, how should I do that?

The mobile connection, on the mobile itself, works fine.

[doktor5000@Mageia9]What does that mean in particular? The connection on your smartphone works fine, but you've never successfully used it on your PC with this setup?

Exactly!

[doktor5000@Mageia9]Also as this seems to be based on some USB device, how do you tether to the phone exactly? Why not simply use a wireless hotspot for tethering ?

I have neither bluetooth or wifi on that particular desktop. But, in order to cover all bases, I did borrow a USB WiFi thing and tested using the mobile's HotSpot. Same frustration!

You forgot an important part, besides the connection details via nmcli:

Also as this seems to be based on some USB device, how do you tether to the phone exactly?

I simply connect the USB cable, and then choose "USB Tethering" instead of "File Transfer" from the connection options available. That's exactly what I do every time with my laptop (not Mageia, though).


Removed duplicate post. ~Germ

[doktor5000]

It has "ipv4.never-default:no" which means DEFROUTE=yes which means that NetworkManager will move the default route to this interface when it's activated.

And you get an IP adress over the tethered connection via DHCP, so that seems to work fine.

Although you still didn't mention if it works if you manually ifdown the other connection.

To configure your tethered hotspot as backup connection you'd have to write a script which needs to at least

Code: Select all

ifdown enp8s0

to remove IP and route for it.

Another option would be to reduce the cost for that interface (metric) as it's currently higher than the wired connection

Code: Select all

nmcli connection modify 'System enp1s0f0u10' ipv4.route-metric 50
nmcli connection reload 'System enp1s0f0u10'
nmcli connection up 'System enp1s0f0u10'

and then reactivate the connection as that is not applied live by networkmanager.

[hosadeeb]

Well, since I only need that tethering in the event my ISP is down, I turned the router off completely. Even then, the tethered connection didn't function. I mean, the desktop couldn't reach the Net, although on the mobile itself the connection worked just fine.

Still, I'll give it a try the modifications you suggested for the tethered connection and tell what transpires.

Thank you a lot for bearing with me.

[hosadeeb]

The connection modifications didn't work either. Unfortunately.

[doktor5000]

"didn't work" is not really helpful. What was the outcome? At least provide

Code: Select all

ip -o r

output, otherwise nobody can really help you remotely.
Also it doesn't matter if you turn off your router, if your default gateway still points to the wired connection as the first in your routing table, then you will still have the same initial problem.
This is the same where simply unplugging your wired connection does nothing if the interface is still configured.

[pmr]

I would check firewall settings.
If you use shorewall, check if the new interface is present in /etc/shorewall/interfaces
