Unable to connect to the Internet

Support Network
1

I am unable to connect to the Internet using my Manjaro system. I am not sure if I lost the ability to connect after an update, or if something else caused the problem. I have not done anything out of the ordinary that I recall. I’ve been unable to connect to the Internet for about one month. Why did I lose Internet connection and what should I do to try to fix the problem? I am not an expert, but I usually fix my problems using the Manjaro wiki and forum. Not this time. Below is some system information.

What kind of internet connection did you used to have?
Wired or wireless?
Only your wired connection shows up here as a possibility - as far as I can see.

3

Wired. I’m connected to a eero beacon, which is bridged with a Verizon Fios router. I also cannot connect using Wi-Fi. I can connect using Windows.

4

What is the output of systemctl status NetworkManager?

That looks good. Let’s check your available devices: ip link

Do you have “fast boot” enabled, by chance? If you are not sure, it might be good to check and disable it before we continue troubleshooting.

9

No, fast boot was/is disabled.

10

Okay, a few other things that might help us identify where the problem is.

ip route should show the IP address of your gateway (your router). If it does not, there’s the problem.

You should be getting an IP address assigned from your router through DHCP. Run ip address, and your device’s IP address should be listed next to the device NetworkManager listed above (enp34s0).

Try to ping your router using the IP address from the ip route command above. If the IP address is 192.168.0.1 for example, the ping command would be ping 192.168.0.1. If the ping is successful, it will keep going until you press Ctrl+C.

Try to ping an external IP address. A commonly used IP address is 9.9.9.9 because it is easy to remember.

Try to ping a website with its FQDN, for example ping forum.manjaro.org.

11

A couple things you could try is connect directly to the router and see if that solves the issue.Also you could update to a newer LTS kernel like 5.10 or 5.15.

12

ping forum.manjaro.org failed. I was able to ping my router IP address and IP address 9.9.9.9

I recall now that I may have made a change to my BIOS when I was trying to remote access computers on my network using NoMachine. I was also creating VMs in Windows at the time. Enabling Hyper-V may have been the BIOS change, which I’m recall from memory a month back, so not 100% sure. Hyper-V is currently enabled. Would that affect Internet connection in Manjaro?

14

I do not know the answer to that, but if so that would be something I have never heard of.

It might be your DNS assignments just need to be adjusted. I have seen cases where Windows is able to work around bad nameserver assignments from the gateway (perhaps Windows has baked-in DNS alternatives), but Linux tends to do as it is told and if you ask it to use a bad DNS server it will just fail.

What is the output of cat /etc/resolv.conf?

15

[mike@mbbrady ~]$ cat /etc/resolv.conf

Generated by NordVPN

nameserver 103.86.99.99
nameserver 103.86.96.96[mike@mbbrady ~]$

16

That may be the crux of the issue right there. Although I do get a ping back from the first address, I cannot get a response from 103.86.96.96.

ping 103.86.96.96 PING 103.86.96.96 (103.86.96.96) 56(84) bytes of data. ^C --- 103.86.96.96 ping statistics --- 272 packets transmitted, 0 received, 100% packet loss, time 277535ms

I am guessing those IP addresses are assigned by your ISP. ISPs are notorious for setting up their own nameservers so they have an easy way to collect information about their subscribers browsing habits. Often times these nameservers do not function well or are broken.

The best fix would be to log in to your router’s admin portal and change your DNS servers to something better. This change would trickle down to NetworkManager automatically and would result in the least amount of fuss. Logging in to your routers admin portal is different for every device, but typically it isn’t hard to find some instructions by doing a web search for the model of your router.

Note: some routers do not allow changing DNS settings. Typically this would only be the case if you rent a device from your ISP and that is how they have configured it.

Another option is to edit your /etc/resolv.conf file to include the DNS servers you would like. You can use nano or whatever editor you are comfortable with to make the edit. The tricky thing is that NetworkManager will automatically update this file with whatever settings it gets from the gateway on your next boot (that is why it is ideal if you can change the DNS server settings in the router itself). You can work around this if you need to by making /etc/resolv.conf write protected by assigning the immutable file attribute to it. To do this, as root run:

chattr +i /etc/resolv.conf

Good DNS servers to choose are OpenDNS: 208.67.222.222 and 208.67.220.220. A lot of folks use the Google nameservers because they are fast and reliable (and easy to remember): 8.8.8.8 and 8.8.4.4.

Again, my guess is Windows has a backup nameserver baked in and is able to work around this on its own. Try changing the nameserver and see if your internet connection is restored.

Do I use 208.67.222.222 and 208.67.220.220 for start and end IP address, respectively? When I try to save I get an error: “IP Addresses: Start IP address is greater than End IP address”

18

Is that an error message you are getting from the admin portal on your router? Is it possible to post a screenshot of what you are seeing?

NordVPN on Manjaro

Due to the way NordVPN work the system nameserver does not get restored correctly - which is the root cause of your issue.

The long version

The short version - be sure you read above topic

sudo systemctl enable --now systemd-resolved
sudo mv /etc/resolv.conf /etc/resolv.conf.bak
sudo ln -s /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
sudo systemctl restart NetworkManager

:point_up_2: My mistake, I did not notice that. Looks like a good tip!

I am connected to the Internet on Manjaro - thanks so much everyone.

I had to reboot to move the .conf file.

In Windows, I successfully changed my DNS server name to OpenDNS (thanks BluishHumility). However, the server name was not changed in Manjaro.
