Internet Servers not found in OpenSuse 13.2

English Network/Internet
#1

Hi I have installed OpenSuse 13.1-64 as dual boot on my laptop: HP EliteBook 6930P, Intel Core2 Duo T9550.
It is working fine and the network too. Wine is installed and working too.
When OpenSuse 13.2 went available, I’ve installed it on another partition on the same laptop. I’ve encounter problem with the Internet.
The Network looks working fine as it find and connect to my router, but is unable to connect to any server on the Web, neither the repositories.
As I never find the solution, I’ve tried to install OpenSuse 13.2-32 to replace the 64 version.
The network is now working. I can navigate the web but Wine is not working.
So when I found that Wine is 64 bit, I’ve reinstalled OpenSuse 13.2-64, forgetting about the network.
I’ve look in OpenSuse forum, but didn’t find answer to my network problem that I was able to apply.
Which files (and directories) from the version 13.1 and 13.2 should I compare to find which setup of the versions are differents.
Many thanks

You’ve got a number of issues here that seem to not be related - please
post a single post per issue (WINE isn’t going to be at all related to
network connectivity issues, for example).

For network issue diagnosis, we need to know what the network card is in
the system - and if it’s wireless or wired.

Hi JIm Sorry for the confusion. I added the info about Wine just to explain why I try different versions and what is working and not with each. I thought it would help. My question is only related to the network connection on 64 version. My network card is: Intel Ultimate N WiFi Link 5300, and the problem is with Wifi connection I forget to say that I’ve tried some settings with the firewall, AppArmor and Proxy, and nothing has worked as you now know Thanks for your answer

It’s unusual that the 64-bit OS install bhaved differently than the 32-bit OS install, but I did find this posting about similar issue reported (with openSUSE 13.1, 32-bit KDE and 64-bit KDE installs)
http://codeverge.com/opensuse.network.wireless/help-selecting-using-intel-wireless/1910944
where the problems seems to be related to missing firmware.

The firmware should be provided by the kernel-firmware package, but can also be got from here
http://wireless.kernel.org/en/users/Drivers/iwlwifi

Thanks deano_ferrari

I will try that

He mentions connecting to the router, so it can’t be that.
I would look at name solving and routing, but I have problems
understanding him (language barrier), so better you handle it :slight_smile:

Okay, but just to clarify further, if you are able to connect to your wireless AP, and you can ping it successfully, then we need to investigate other possible issues.

For example, can you ping by IP address?

ping 8.8.8.8

By domain name?

ping google.com

Is a nameserver assigned? (It might be the router address for example)

grep -i nameserver /etc/resolv.conf

could you please sort the text out in readable sections, rather then 1 big line with text?

I’m sorry I’m unable to have line return

What append

what you post here is more or less unreadable / understanding in order to help you

could you at least change the opening topic in readeble sections?

I've tried the iwlwifi:    From the wireless.kernel.org,

 I've downloaded  and tried this file : Kernels 2.6.38+ iwlwifi-5000-ucode-8.83.5.1-1.tgz   which contains  iwlwifi-5000-5.ucode 332.7 Kb dated 2011-04-20 11:48

   The one from OpenSuse 13.2 is dated 2014-08-28 10:51

  No success

    I've  tried: to ping    ping 8.8.8.8  64 bytes from 8.8.8.8: icmp_seq=1 ttl=55  time=23.9 ms    ping google.com  ping:

Okay, it looks like you have internet connectivity, but no nameserver configured. (Usually assigned by the router for DHCP connections.)

One way around this would be to add a nameserver manually

echo nameserver 8.8.8.8 > /etc/resolv.conf

Then you should be able to browse the internet. (Most domestic DSL routers will also act as DNS servers if you substitiute the address above with the router address.)

NB. It won’t be overwritten until you remove it in the future though.

#14

You could also try to run this to recreate /etc/resolv.conf from scratch:

sudo netconfig update -f

If you’re using DHCP (which you do probably), this should normally be able to determine the correct nameserver (the router should tell your system).

If this doesn’t work, you could still add a nameserver (like 8.8.8.8) manually.

Thanks for you help Sorry for the previous text formatting. I’ve tried to correct it many times, but nothing works. There’s something I don’t understand I’ve run this command: echo nameserver 8.8.8.8 > /etc/resolv.conf and I can now surf the web After, I’ve run this command: sudo netconfig update -f And it reset the resolv.conf file without DNS, and the internet access is blocked Now I have a workaround to be able to surf the web After that: I’ve start to install OpenSuse 13.2 64 (DVD) again, to try to find out what I did wrong In the network config step, I put an IP address for the card (192.168.1.100) and a Hostname (GLElite) and filled all the other fields as usually (Network name, password…) The system is unable to connect to the web to update the online repositories. I’ve tried a lot of setup and was unable to start the network during the installation I think there are 2 problems 1. The installation can’t start the network card and connect to the router (to update the repositories) 2. When OpenSuse is installed it connect to the router, but can’t automatically manage the DNS like the other versions The router has always the same config. I think I install 13.2 64 the same way I did for 13.1 64 and 13.2 32 and both are working fine I hope you can find a solution to solve these bug at the installation times. Thanks again for your help

Sorry for the text formatting. I’ve tried to correct it many times, but nothing works. There’s something I don’t understand

I’ve run this command:
echo nameserver 8.8.8.8 > /etc/resolv.conf
and I can now surf the web

After, I’ve run this command:
sudo netconfig update -f
And it reset the resolv.conf file without DNS, and the internet access is blocked

Now I have a workaround to be able to surf the web

After that:

I’ve start to install OpenSuse 13.2 64 (DVD) again, to try to find out what I did wrong

In the network config step, I put an IP address for the card (192.168.1.100) and a Hostname (GLElite) and filled all the other fields as usually (Network name, password…)
The system is unable to connect to the web to update the online repositories.

I think there are 2 problems

  1. The installation can’t start the network card and connect to the router (to update the repositories)
  2. When OpenSuse is installed it connect to the router, but can’t automatically manage the DNS like the other versions

If you setup a static IP address, you also have to specify the DNS-Server yourself, which apparently you didn’t.

I think there are 2 problems

  1. The installation can’t start the network card and connect to the router (to update the repositories)

Yes, because your settings are wrong, it seems.

  1. When OpenSuse is installed it connect to the router, but can’t automatically manage the DNS like the other versions

It can, if you use DHCP.
It should then get all necessary settings from the router.
If you configure it manually, you have to provide all settings and they have to be correct.

I think I install 13.2 64 the same way I did for 13.1 64 and 13.2 32 and both are working fine
The router has always the same config.

You probably have not changed the network card settings there. The default is to use DHCP to configure everything automatically.

So, try to set “DHCP” in YaST->Network Devices->Network Settings, and it should work. (or alternatively, configure a DNS-Server there, probably either your router’s IP or 8.8.8.8, which is Google, should work)
But as you modified /etc/resolv.conf manually, you probably should remove it first.
