I just upgraded to openSUSE 13.1 from 12.2, and since then I have not been able to connect to the Internet from Linux. Web browsers function normally, but cannot connect. The clock cannot connect to the time server, and update checks fail to connect. (I am posting this via Windows.)
I am getting 3 of 4 bars for wireless connectivity, which is normal for my setup. I use Gnome’s nm-applet instead of KDE NetworkManager because I have never been able to get NetworkManager to work properly.
Any idea why I can’t get Internet even though I’m getting a strong wireless signal?

If a Web browser cannot connect to the Internet, it hardly seems that they are
functioning normally.

The KDE applet works great for me.

It is likely routing or name service.
Have you checked the routing using ‘route -n’?
If that is correct, can you ping your router by IP number?

Most likely DNS is not properly set. What do you get from:
cat /etc/resolv.conf | grep nameserver
Try using google’s public DNS servers 8.8.8.8 and 8.8.4.4

It looks as if you are using DHCP.That means that your DHCP server (the router) will give you an IP address (you got it), a default router (you got is) and the address of a DNS server (often the router itself). But that last one does not show in your /etc/resolv.conf.
The most likely reason for this is that someone/something altered that file “manualy”. Now the automatic process (the DHCP client) guesses that there is there a prefered configuration and does not change it to not frustrate that manual configuration.
Now you can walk two ways:
Check the comment lines in /etc/resolv.conf. They should read:
### /etc/resolv.conf file autogenerated by netconfig!
#
# Before you change this file manually, consider to define the
# static DNS configuration using the following variables in the
# /etc/sysconfig/network/config file:
# NETCONFIG_DNS_STATIC_SEARCHLIST
# NETCONFIG_DNS_STATIC_SERVERS
# NETCONFIG_DNS_FORWARDER
# or disable DNS configuration updates via netconfig by setting:
# NETCONFIG_DNS_POLICY=''
#
# See also the netconfig(8) manual page and other documentation.
#
# Note: Manual change of this file disables netconfig too, but
# may get lost when this file contains comments or empty lines
# only, the netconfig settings are same with settings in this
# file and in case of a "netconfig update -f" call.
#
### Please remove (at least) this line when you modify the file!
Specialy the last line is important (as it says there) because it triggers the automatic entering of the DNS server.
After checking and maybe repairing, reboot and see if you are OK now.

Do as venkzep suggested. Add the Google DNS servers to the file. I do not know how you tried that (you speak of a greyed out button???), but use an editor of your choice as root and add the following lines at the end of /etc/resolv.conf:
nameserver 8.8.8.8
nameserver 8.8.4.4
Remove the line
### Please remove (at least) this line when you modify the file!
Well, as you changed the file file now, nobody can prove this anymore. But when it was, I did not mean that you did that “willingly”. It can be done poking around in YaST, Network manager and back again. We see it happen now and the. Mostly after the system manager can not reconstruct exactly what he did over time. lol!
It should not look like. It should be this. And I posted the text, you only have to edit the file and replace the existing text with the one I gave you. But you choose for the other option and that is OK.
Thanks!
