Cannot connect to wired internet in Opensuse 12.1

English Network/Internet
1

Hi friends,
I am coming from applications section.
I’ve installed Opensuse 12.1 with gnome 3.
There is no problem with my wired connection till i configured the wvdial.conf username and password for my new wireless modem.
Since then, i cannot connect to the internet using the wired connection, however i can connect through the usb wireless modem.
When using wired connection, the LAN icon near the battery/bluetooth indication shows as connected to internet and a popup displays that its connected to local area network but I can’t access the internet.

Please help.
Thanks.

It is very likely that you are still configured to use Traditional Method using ifup which supports one connection at a time. So you need to select Activities, find and run YaST and enter the root user password. In YaST find Network Devices, Network Settings and open it up. Go to the Global tab, and select the bullet for User Controlled with NetworkManager. Accept the warning and press the OK button on the bottom right of the window. Now you should get a small network icon on the top right to select your connection from.

Thank You,

ping -c 5 173.194.69.147

The result is:

Here is what I get with the same command:

ping -c 5 173.194.69.147

you ARE connected to the internet! otherwise you couldn’t be getting
those ping replies!

what is the problem?

well, most machines won’t know what to do it you try to use the wired
(ethernet) connection to the net WHILE the wireless is working…also,
if the wired is working it might go crazy if you try to at the same time
go wireless–so, use one at a time…

Dear Denver,
You didn’t completely understand my situation - (Hmm its my fault i didnt mention it)
See, I have three sources of Internet access - only three.

  1. My home - 2Mbps Broadband connection (ISP: BSNL) - This one is wired and this causes the problem in my openSUSE (but works fine in windows)
  2. College - Wifi
  3. My wireless modem - 3.1Mbps Broadband (ISP: Reliance)

At one time, I will have only one source of internet. (When at college, college wifi, when at my room (near college) my wireless modem and when at home - wired bsnl broadband)

So, Now I am on my wired connection which is causing the problem. As you said, I tried the ping and got the reply only from my wired connection - believe me!
But i cannot access the internet - help me!

Regards,
Anish

well look, maybe i do not understand exactly what you write above, but i
see: “Now I am on my wired connection” and you are writing to me and i
received it…i received it through the internet…so you ARE
accessing the internet, and sending info to me through the internet!!

so, you have
no wifi problem at school
no wifi problem using your wireless modem
no wired problem at home

so, WHY do you say you “cannot access the internet”? what do you mean by
that exactly?

i mean, you can use a browser, right? (you must have used one to type
“Now I am on my wired connection” above, right?)

so, what is it that you cannot use when wired and therefore say “cannot
access the internet”:
-Skype
-msn
-irc
-email
-hotmail
-twitter
-google
-facebook
-youtube
-google +
-myspace
-etc
-etc
-etc
-etc

btw: i have a good friend visiting in India just now…and another good
friend who is half Indian and living in Copenhagen…

Hi Denver,
Again i am responsible for your confusion! I failed to mention that i am having a pc@ home running windows.
I cannot access internet from my lappy running opensuse 12.1 gnome-3

I am typing this very post from my pc

i have a good friend visiting in India just now.

Count me too (strike out good) :wink:

ok, so this problem computer is a laptop running Gnome 3 which i know
less than nothing about!

so, most modern laptops have some key combo which turns off its internal
wi-fi, if the laptop is now running i want you to turn off the wi-fi
using the key combo (look at your laptop documentation to learn how, if
you don’t know)

then, shut down the laptop and remove the plug in wireless modem

then, attach the wire from your broadband modem to your laptops ethernet
port and boot up your openSUSE 12.1

when i comes up, open a terminal and issue this command


ping -c 5 173.194.69.147

if you get ping replies use Ctrl+c to stop the ping and then issue this
command
ping google.com

if you get replies, open your browser and welcome yourself to the internet…

if you didn’t get to the net with the browser…hmmmm, do this are
return the in/output to here:


/sbin/ifconfig -a
ping 192.168.1.1     <*or* your-router-IP-address>
/sbin/route -n

and, one more question: what else have you forgotten to tell?

Hello denver, At last! finally I found the problem… Thankyou Denver for you support… This is what I did: 1. first fed the command “ping -c 173.194.69.147” into the terminal and yes I got ping replies 2. I tried “ping google.com” and got the error “ping: unknown host google.com” 3. Just something flashed in my mind… I entered “173.194.69.147” in the browser address bar - know what? I got google :smiley: Now I figured out that I’ve messed something with the DNS - please guide me here.

and, one more question: what else have you forgotten to tell?
Are you angry with me?

12

problem solved! - I opened up the network settings -> configure
There under IPv4 tab, i selected Automatic DHCP address only (before it was Automatic DHCP) and rebooted
The problem was solved! and under the IPv4 tab, it again changed itself to Automatic DHCP - but i got the wired connection working!

Thanks to Denver - - - - - - -

One more question: why cant I edit my posts? I mean when i edit, It says the moderator has disabled edit for me! and now, i dont have the edit button on my posts.

13

All users are limited to about 10 minutes to edit their posts. After that, it can not be edited except by a moderator. Basically it makes you responsible for what you post when you post it as you can’t take it back. We also have NTTP users that have issues with changes in the message thread after a small period of time. If you have some real issue as in posting technical data that is flawed, just ask a moderator for help. Otherwise, you can also post a correction in the thread that you responded in and don’t worry about it. We all make mistakes here.

Thank You,

Please run the command ‘cat /etc/resolv.conf | grep -v #’ and post the results.
Being able to ping an IP, but having it fail with a name is a sign that DNS is
failing.

Hi here is the output of the command you gave, please help.

anish@linux-jmbg:~> cat /etc/resolv.conf | grep -v \#

am HAPPY you are making progress!! good find on the DNS problem, that
was exactly what i was trying to find when i asked you to ping both
google, and its IP address, so now we think we know the problem, so:

hold down Alt and press F2, a ‘run command’ should open up (though i
know you are running gnome 3 and i have NO idea where it will be, or
what it might look like–or even if it will actually pop up)…

into the popped up run command type


gnomesu gedit

and, give your root password when asked…
when gedit comes alive, navigate to /etc/resolv.conf

and CAREFULLY modify it to look like this:


#nameserver 220.226.6.104
#nameserver 220.226.100.40
nameserver 8.8.8.8
nameserver 8.8.4.4

the “#” tells the system to NOT read that line, and the two new
nameservers are free ones provided by Google to the world and are known
to be better, faster and more IPv6 friendly…

save it and then try browsing to www.google.com again…

i think it will work…but, you may need to restart networking…there
is a way to do that without booting, but i forget the details…you can
look it up with a carefully crafted google using the site specifier of
site:forums.opensuse.org

and, regards your question “Are you angry with me?” the answer is: no,
not angry but we all need you (and all the others asking for help) to
recognize the fact that we can’t see your machine or monitor…we have
no idea if you sitting at a supercomputer or a net book, running KDE or
just command line terminal…so, it is up to you to tell us what is
going on…

Yeah got it.

And again, thank you Denver, Iwfinger and James.
I learnt much through this problem. (for me its muchrotfl!)
You people made me a student penguin and I am happy that I learnt something.
Perhaps, in future, i may help someone with the same problem or sort it out myself when it comes to me!

At the midst of this problem, I felt desperate and it occured to me to format my system and install fedora or Mandriva! But something kept me from doing it (I think its the force :smiley: )

Have a nice day flux capacitor penguin, May the force be with you:P
