Internet is not working

ShailMurtaza

Hi!
I tried to connect with PPPoe connection using rp-pppoe but that didn't worked.
After that when I tried to use WiFi which was working fine before, was not working. I was connected to WiFi and had access to network. I can open routers login page but internet is not working.
I tried to restart NetworkManager and reboot but nothing was working. I was unable to access internet even using ethernet
Can anyone please help me?

pomon

First, see what interface is connected nmcli connection show and systemctl status NetworkManager What the ping shows ping google.com. You can also try to uninstall rp-pppoe, remove wifi connections in NetworkManager and configure the connection again.

Here you have more about nmcli

pomon

output of ping is ping: unknown host
systemctl status NetworkManager Active
DEVICE: wlp3s0

pomon

Or maybe you would write something more.

What are the active connections?
Have you removed the package and connection and created new ones?
If you expect help, provide as much information as possible.

I have a WiFi connection
I created a new connection but that didn't worked. I tried to use ethernet but that didn't worked
rp-ppoe was not installed using eopkg so I could not remove it using "eopkg remove"

brent

~$ sudo systemctl | grep network
Password: 
  network-online.target                                          loaded active active    Network is Online
  network.target                                                      loaded active active    Network

I think pomon is very on target about: a possible services issue and you should really give more information than you are giving about the driver install and circumstances and observations etc etc. You seem to have brought in and installed a 3rd party (outside of repo) driver that maybe swang a sledgehammer around your Budgie. This is likely very solvable.
Also it never hurts to see if a package is broken: sudo eopkg check

Output of sudo systemctl | grep network is same as yours
I checked for broken packages and everything seem to be alright
Only this file is missing which I don't think is related
Missing file: /usr/share/fonts/conf.d/66-noto-color-emoji.conf Broken
Please let me know if there is any other detail you want and what type of details should I provide?

I had my WiFi go out two years ago and I've never been able to make it work consistently again. After much trials and many curse words being uttered I found out that, in my case, it was a kernel issue.

There were two things I did to ensure that my internet connection is fast, reliable, and never gives me problems.

First.. I switched to the LTS kernel. That fixed my issue immediately. However I sporadically had connectivity issues and so I had a second option which I use right now. Since my ethernet port was broken I bought a USB ethernet cable.

I get why ethernet connections would suck for most people. However my laptop doesn't move so it works for me.

Let me explain the process of setting up the LTS kernel. I have a strong feeling this might be kernel related and changing kernels is surprisingly easy. For reference here is the Boot Management help file from the main Solus Site

Check your Linux Kernel.
In a terminal type uname -r. It should say "5.15.50-216.current".
Displaying the Solus boot menu by default on boot
In a terminal type sudo clr-boot-manager set-timeout 5 && sudo clr-boot-manager update
Install the Linux LTS Kernel.
sudo eopkg up linux-lts linux-lts-headers.
Once you do this you are going to need to reboot. You can type reboot in the terminal or do it manually.
After rebooting the Solus boot manager should display. There should be 2 or 3 options. The current kernel is 5.15, the LTS kernel is.. I believe.. 4.14. (In case the option isnt there, continue reboot normally and then reboot again.. the kernel may not have been added yet.)
Once you login check your kernel by typing uname -r again.

When your kernel gives you the output that says 4.14.xxx-xxx.lts or something similar then you are running the LTS. This is when you check your WiFi connection.

If it works then you can choose to stay on the LTS kernel by typing:
sudo clr-boot-manager update

Let me know how this turns out for you.

jrsilvey

Changing kernels can be intimidating. I laid out all of the instructions that I use to do it and the process is super easy. Try not to deviate from any of the instructions I gave.

In my case my internet connectivity issues were kernel-related. I am hoping that yours is as well. If you DO have internet stay on the LTS kernel. If you DO NOT have internet on the LTS, then switch back to the current kernel.

Type uname -r to see your current kernel.

You can revert to the current kernel by typing:

sudo clr-boot-manager list-kernels

It should be give an option that shows the LTS and the current kernels. 5.15.50-216.current is the most up to date kernel.

Then type sudo clr-boot-manager set-kernel 5.15.50-216.current

When you are successfully booted into the current kernel type sudo clr-boot-manager update to boot into the current kernel every time instead of the LTS upon start up.

Use the same process to boot into the LTS kernel if that is your issue and your internet works using it.

jrsilvey Do I need internet connection for this?

xahodo

Your router seems to respond to ping, which means that your wifi is functioning.
Have you got some strict firewall rules up? If so, could you try without the firewall and check again?
Are you able to get to your router's webui using your browser? If so, it might be a problem with your internet connection or your router's firewall and not with Solus.
Something else you might want to check is whether you get a dynamic ip from your router (in which case dns is automatically configured) or you configured a static ip (in which case you need to point solus to a dns server).

ShailMurtaza

xahodo It is not router's problem. Many devices are running on that router. I'm not using static ip but I have tried to use static ip as well.
Yes! I'm able to get login page of router and I can also access to local web servers from solus. I have dual boot windows 10 whom WiFi is working fine
I also checked router's config to see if there is something like bandwidth control or something like that
Can you please tell me how to disable firewall? I tried to use ufw disable and systemctl stop firewalld but that didn't worked

jrsilvey

ShailMurtaza You sound like you know what you are talking about with your router and I strongly suggest you check and see if it is a kernel issue. Im sure you can follow the second set of commands without needing the internet.

Im more certain that this is something kernel related now that you said everything else works on the router. I had an issue with my realtek WiFi driver which made my second laptop unusable for months. I tried everything. It wasn't until I did the kernel change that I was able to get connectivity again.

jrsilvey

Sorry for the delay in responding.

I hadn't considered that. sudo eopkg up does use the internet.

Ok.. You can still change kernels though.

uname -r to see your current kernel. Write down what the number is.

sudo clr-boot-manager set-timeout 5 && sudo clr-boot-manager update to set the Solus boot manager.

The type reboot right in the terminal. When you reboot you will see the Solus boot manager.

You will have five seconds to choose a kernel from a list. If you press the arrow key up or down that will stop the timer.

Pick the kernel that is the opposite of whichever you have installed. Solus keeps a backup of the kernels as a fallback in case something borks your computer. Press the Enter key to select that other kernel.

If your internet works with the other kernel, you have a kernel issue and not a Solus issue. You have to wait for an update to the kernel.

If your internet DOES work while logged in using the other kernel, type sudo clr-boot-manager update to set the make this your new default kernel.

You can do ALL of this without the internet, I am sure.

jrsilvey Your suggestion might be very useful in future
Thanks for that 😀 😃

xahodo

I don't think it's his kernel, as he's able to ping the router, and the interface shows as being up.

I'm more inclined to think that he has a misconfigured firewall. Anybody in here know how to disable ufw AND make it reset iptables to the default state?

elfprince

xahodo sudo ufw off sudo ufw reset
man ufw

ShailMurtaza

elfprince sudo: ufw: command not found

elfprince

ShailMurtaza Is ufw installed? try whereis ufw, to see if it is. I don't think it is installed by default. I rememmber that I had to install and activate it.

brent

elfprince correct on all of that

jrsilvey

elfprince OMG I never knew about this command whereis and it's awesome.

Hi guys. Thanks for your help. I'm able to run the internet. It was not kernel or firewall issue. So here is what I did.

I noticed two things. systemd-resolved.service was not enabled and not running. Second one was /etc/resolv.conf file was missing.
I enabled and started the systemd-resolved.service but that didn't worked. Rebooted, systemd-resolved.service was running but internet still wasn't working.
I created resolv.conf file and put nameserver 192.168.0.1 in it since this file was not created by resolv service even after reboot. Restarted systemd-resolved.service. It didn't worked. Then rebooted and still didn't worked.
Then I delete resolv.conf file rebooted. This time internet worked I don't know how and why. But this time systemd-resolved.service created resolv.conf file automatically which content was nameserver 192.168.0.1.

I does not really know why systemd-resolved.service didn't created file first time when I rebooted. But now internet is working fine. What you guys think about this?

brent

ShailMurtaza Now that you've had some time, do you believe your install of the github driver (rp-pppoe) disabled the resolve service and toasted the file?
