No network and intenet [SOLVED]

[pujithadimuthu]

OS: Windows 10 Pro x64 and Mageia 9 x64 (Up to date)
Desktop: HP ProDesk 600 G1 Tower PC
Network: Intel(R) Ethernet Connection I217-LM

Windows I can connect to network and the internet. but in Linux sometimes I can not connect (connect and disconnect..) to internet and network.
Checked both auto and manual. DNS 8.8.8.8 and 8.8.4.4

Hi there, how should the dxdiag from windows help us figure out why your network connection under Mageia does not work _sometimes_ ?

[pujithadimuthu]

what do you need?

[doktor5000]

Some actual details on your network connection under Mageia? And some more information on when it works and when not.

At least the output of the following commands would be required:

Code: Select all

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

ping -c4 8.8.8.8
ping -c4 <IP_of_your_router>
nslookup mageia.org
ping -c4 mageia.org

yesterday night I installed the OS. Updated the OS. After the update internet connation got issues as I understand.
sometimes if I change auto to manual and manual to auto network worked.
Now internet not working.

Problems occurred during the network connectivity test.

This can be caused by invalid network configuration, or problems with your modem or router.

You might want to relaunch the configuration to verify the connection settings.

---- what will happen if i put yes to "allow interface to be controlled by network manager"?

Added code tags to output of commands. ~Germ

There's no connection to your router, hence also no internet connection.

---- what will happen if i put yes to "allow interface to be controlled by network manager"?

Nothing, that would allow networkmanager to manage the interface if you would use networkmanager.

Maybe it would help if you simply switch to networkmanager:

if i do not have internet how can i write these sentences? That is the problem. no connation to router or internet.. from the OS. Router is working

Please use code-tags when posting output.

Also what is your ping output supposed to show? You ping your loopback adress and your own local IP adress, you still don't have a working network connection to your router.

today morning installed openSuSE Leap 15.6 x64 (Updated) in a separate hard disk. it is working fine. FYI

[pujithadimuthu]

Today managed to get an update. Now OK. Thanks...

Please don't forget to mark the thread as solved, by editing the subject of the first post and prefix it with [SOLVED], thanks in advance.
