Network OK but no internet [done]

[JJF1]

Dual boot system: Windows 11 and Mageia 9 installed on Asus laptop.
Only in the last 2 days when I boot Linux, I am unable to access any internet site
(If I boot Windows, I can access the internet with no problems).
Please advice

Well, you would need to troubleshoot your network connection first, but you don't include any details.
At least the output of the following commands would be required:

Code: Select all

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

Code: Select all

[doktor5000]

Well, you have an IP adress and a default route to your router, and nameservers point to your router and the second to google nameserver.
Looks fine so far, how do you actually test internet connectivity in particular?

Please also post the output of

Code: Select all

ping -c4 8.8.8.8
ping -c4 192.168.1.1
nslookup mageia.org
ping -c4 mageia.org

[doktor5000]

So that seems like a problem with your router then, if you can't even ping it. What type of device is 192.168.1.1 actually ?

Do you have any kind of firewall on your Mageia box enabled ? Please post the output of

Code: Select all

iptables -L -v -n

[JJF1]

[I have to switch from Linux to Windows and vise versa in order to read the Linux data / command requested and back to Windows to submit ans be able to send the reply].
BTY, I could, only, run this command as Root

Code: Select all

iptables.txt

Chain INPUT (policy ACCEPT 32 packets, 2944 bytes)

Chain OUTPUT (policy ACCEPT 62 packets, 4876 bytes)
 pkts bytes target     prot opt in     out     source               destination         



[JJF1]

No firewall exists. niether in the router nor in Mageia.
(It did not change before or after the internet connection was lost)

[doktor5000]

Please also post the output of

Code: Select all

ip -c -o l

I just checked again your output from "ip -o r" and it shows as linkdown which indicates that the link/interface for that connection is down currently.

It would be helpful if you could run

Code: Select all

journalctl -ab > /tmp/journal.log

as root after a fresh boot, and then later attach /tmp/journal.log here.

[isadora]

Code: Select all

ip -c -o l

journal -ab is longer than the allowed size (>60000 charachters) . Please advice

[JJF1]

As the size of journalctl exceeded the permited size, I "grepped" it to filter only 'network' , as it is quoted below (I hope it contained a clue to the solution):

See the relevant excerpt above, you need to clean up / fix your network interface configs. eno2 does not have a link, that's why you don't have an internet connection or connection to your router.

[Well, even after 10 years of using Mageia, I am still ignorant vis-a-vis using the various feature as well as the Forum's help]
Attaches below is the required root journalctl after boot.
I do want to mention that local network communication is ok, i.e. connection to the router is alive.
Ready to get more help.

I do want to mention that local network communication is ok, i.e. connection to the router is alive.

You mean after a fresh boot? Because according to your previous ping output it was not reachable.

Apart from that you seem to have configured both your wireless and wired interfaces to use the same adapter so they are conflicting.
Best remove those two and make sure to delete or rename/move away /etc/sysconfig/network-scripts/ifcfg-eno2 and /etc/sysconfig/network-scripts/ifcfg-Auto_Frommer3
(when renaming make sure the name does not start with ifcfg-) and then configure your wired interface fresh.
