Kevin, Vladimir, can you take a look into 'dmesg' output and into /var/log/messages, /var/log/boot.msg if you find kernel Oopses as in bug 537350 comment 6? [Must not be related - just because you've disabled IPv6.] (In reply to comment #0)

Weird. You can ping the home via wlan0 from 11.1 but you can not from 11.2. Right ? What can be the difference if the AP is between and you can ping the AP from both 11.1 and 11.2 ?

Good question. I don't know.

Anyway, you can connect to the Internet from eth0. If I understand it right you cannot connect to the Internet from wlan0. It happens when you unplug the ethernet cable from the box. Right ?

If the eth0 is unplugged there should be no route via eth0 anymore.

I think maybe you misunderstood. I don't want to use both at the same time. I want to use either or. I usually use wlan0 so I don't have to run a 50 ft ethernet cable to the router from my computer. But sometimes I need to use the ethernet cable, such as when I'm changing settings to the wireless router or if I need the added security of a wired connection. I also discovered that I can have the same problem in reverse. I did a clean install of Milestone 8 and only wlan0 was configured. Then I added the eth0 configuration and eth0 can't ping any websites, only the assigned ip address. I have never had this problem before, going back to openSUSE 10.0. It only popped up in the Milesone releases for 11.2. So I edited /etc/sysconfig/network/ifcfg-wlan0 and eth0 like the examples above and both interfaces are working now. Shouldn't YaST do this automatically when more than one interface is configured? Why haven't I had this problem in the past? Is this a problem with ifup but not with NetworkManager?

OK.

OK.

YaST did this until now.

Is this a problem with ifup but not with NetworkManager?

NetworkManager has a daemon that AFAIK automatically selects the fastest interface, that is, this setup is default for NetworkManager.

Surely you don't expect new users to edit /etc/sysconfig/network by hand if they configure both wired and wireless interfaces.
