Networkmanager - no route after User-Switch - Suse 11.2

English Network/Internet

Hi everyone,

hopefully someone could help me. Here’s my problem:

The System:

  • KDE 4 - NetworkManager is used to access Mobile Internet with a USB Stick K3565-Z (Vodafone).

The Problem:
Above config worked until I switch to another user, while a mobile connection was active. Then it wasn’t working with the user I switched to. As I tried to get NetworkManger working again on this user, it doesn’t worked on all users anymore. Meanwhile I reinstalled NetworkManager, ppp, vodafone-mobile-connect software and so on. The stick is still recognized by NetworkManager, but when a connection is established no Websites could be viewed in Firefox or the like.

While investigating the problem, I setup another Desktop PC to use the stick and found that the above mentioned Notebook doesn’t have the same Routes as the Desktop PC. The Notebook only has:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
loopback * 255.0.0.0 U 0 0 0 lo

While the Desktop PC shows:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.64.64.64 * 255.255.255.255 UH 0 0 0 ppp0
loopback * 255.0.0.0 U 0 0 0 lo
default 10.64.64.64 0.0.0.0 UG 0 0 0 ppp0

But if I try to add a route, the following error message appears:
SIOCADDRT: No such process
or
SIOCADDRT: No such device
depending on the route add command.

Furthermore, there is no ppp0 or the like on the Notebook anymore, while the Desktop has lots of them.
However, as the stick is recognized and it is possible to establish a connection, I assume that the Problem must be the Route and/or the ppp stuff.
ppp had been newly installed, but still no changes to routes and interfaces.

Now, I have no clue how to solve the Problem.
Any ideas? All help is welcome.

Thanks.

I can report the same problem here.
After configuring the network with Network manager and obtaining a successful connection, there is no default route.
I tried deleting the configuration and restarting, without success. The network is detected by network manager, the
information is handled, everything EXCEPT adding a default route. I can of course add it “by hand” but it appears to be
a bug in NetworkManager.
The problem does not appear when connecting via ifup/ifconfig/iwconfig to the same wireless network.
Any ideas?

Thanks,
