OpenSuse 11.3: unable to connect to network, WLAN connectin is up

Hi

In OpenSuse 11.3 i can’t connect to the network. With DHCP i don’t get a IP-adress. If I configure the adress manually, I can’t even ping the IP of the router. But the WLAN connection ist up, I can see the connection in my Fritz!Box.

route -n gives

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.178.0   0.0.0.0         255.255.255.0   U     0      0        0 wlan0
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 wlan0

I don’t know, where the 169.254.0.0 comes from.

With whireshark I can see some traffic (LLC protokoll) between the router and an other linux box, but no TCP/IP traffic.

lsusb for my WLAN stick is:
Bus 001 Device 005: ID 114b:0110 Sphairon Access Systems GmbH Turbolink UB801R WLAN Adapter

It uses the rt2500usb driver.

The system worked with 11.1 and 11.3RC1 without problems.

Can anybody tell whats going on?

Lars

I have the same issue but with a iwlagn (intel wifi card), I have described it hereIntel 4965 doesn’t work on OpenSuse 11.2

That is a Zero Configuration Address. If an interface is unable to obtain an IP
address through DHCP, then it gets a 169.254.0.X address. That lets two devices
connect in an ad-hoc network where there is no DHCP server.

What does “/usr/sbin/iwconfig” show? In addition, please check
/var/log/NetworkManager. Is IPv6 enabled? Do you need it?

As far as I know, there were no changes in any networking component between
11.3RC1 and 11.3.

IPv6 is disabled ( I tested with enabled IPv6, doesn’t change anything). I am using ifup, but testing with netwokmanger there was nothing abnormal in /var/log/NetworkManager except that autofs script gave an error, but I blame that on the missing net.

ifconfig on same machine, OpenSuse 11.1:


wlan0     IEEE 802.11bg  ESSID:"Matrix"

The signal qualtity seems to be better.

I have what seems to be the same problem:
Wifi doesn’t work
For some odd reason, neither the Atheros nor the Linksys (rt73usb in my case) works. Hopefully, someone has a solution to this problem.

I had a similar problem. I fixed it by not using the traditional ifup setting but used networkmanager. Go to yast and wireless setup. Under general tab you will see a set of radio buttons. One if for networkmanager and the other is for ifup. Use networkmanager. Yast will nolonger control the the wireless nic but networkmanager will. Then click on the icon for networkmanager in the systray and input your passphrase.

For those that can get info to the developers the problem with the traditional ifup is it doesn’t set the passphrase so you don’t get to the dhcp server so no ip. The nic comes up but it has no ip ( confirm with ifconfig ). If one does iwconfig you see that there is no passphrase. But networkmanager does set the passphrase.

Using netwokmanager doesn’t change anything. I don’t think its a problem with the passphrase since my FRITZ!Box tells me I am connected.

Same problem here.

Two comments: (1) I tested ifup and it works if configured correctly. (2)
Putting a message in here for someone to contact the developers does no good.
When you find a bug, you need to report it in the Bugzilla.

For wireless, ifup is hard to use. Finding the place to set the passphrase/key
with YaST is difficult. You can also edit /etc/sysconfig/network/ifcfg-wlan0,
but that is pretty obscure. For thos reasons, NetworkManager is better as it
looks after the details.

I had/have problems with wifi rt73usb on opensuse 11.3. Networkmanager didn’t work either in opensuse 11.2 and it isn’t better in 11.3. Networkmanager see AP and when I connect to AP I must provide password twice, why? Then was obtaining ip address and nothing (disconnected). I moved to traditional ifup method (that worked fine in opensuse 11.2) with this usb wifi stick and I can’t get ip address again like with networkmanager. I checked iwconfig and see I am associated with my AP, but still can’t get ip address from it. Then I disabled ipv6 in Yast and configured only dhcp4 daemon wlan0. Next I checked /etc/sysconfig/network/ifcfg-wlan0 and set WIRELESS_WPA_PSK password (I have WPA authentication), then reboot. After that I can get ip address from AP and wifi was working. But sometimes when I turn on PC and login a I haven’t wifi connection estabilished yet and must wait 10-20s when I get ip address.

Try WICD with ifup

I did an update today, and for some reason, networkmanager seems to be working now. Thanks openSUSE (Novell) devs!

After installing compat-wireless-2010-07-31 my WLAN works as before with 11.1.
