Wifi worked great: now, I'm connected but no data

English Network/Internet

I’ve got a Thinkpad T61 laptop that has been running 12.1 w/few issues until now…

The wifi has been working great w/my home network, installed and configured nicely, however this evening even though I was connected to my Linksys router I am unable to send or receive packets. Upon closer inspection, I discovered that my wifi receiver was not in the list of devices allowed access through the firewall. I then reconfigured the wifi receiver in the laptop using a functional T60 running 12.1 as an example. No luck. I see packets being sent in my Conky dashboard, but none are coming in. Opening a terminal and typing ping cnn.com gets me no response.

Any suggestions? This is bizarre. I’ve reinstalled the wifi receiver 3 or 4 times and tried modifying settings w/no luck.

Thanks. Bye.

…in addition, turning the firewall off has no effect, packets still do not come in.

Any chance you ran into this bug: https://bugzilla.novell.com/show_bug.cgi?id=727857 ?

I don’t think so, although the install is a 64-bit. The problem seems somehow related to the firewall. Packets go out from my computer, but they do not come in. Curious that this problem persists with the firewall turned off. I’ve also recreated the configuration of a working T60 running 12.1 in the T61 with no luck.

How do you know that packets go out?

I think you may have either a routing or DNS problem. Please post the output of


/sbin/route   -n
cat   /etc/resolv.conf

In the latter case, please remove all the lines that start with the # symbol.
They are comments.

Got it.

Resolve.conf is an /etc file that I am not familiar with.
It appears that the nameserver and search IPs had magically changed themselves in this file to my work network which is behind a firewall. I find this very curious as I have been using laptops configured in this exact manner for several years and this is the first time that has happened. The only change is that I have changed from Gnome to XFCE with the 12.1 version of openSuse.
But that’s another thread.

Thanks for your help and illumination on the source of this problem.
