Networkmanager can't disconnect wired, wireless and dsl connections

[Phoenix]

Networkmanager is now able to have multiple network connections online, but there is now way of tearing a connection down or disconnnect a connection. In my setup, my office, I'm able to connect via the low speed wireless or the high speed wired network, which leads to situations, where both networks interfaces are up - and as I do assign static IPs, both interfaces receive the same static ip.

eth0 Link encap:Ethernet
          inet addr:192.168.170.251 Bcast:192.168.170.255 Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

eth1 Link encap:Ethernet
          inet addr:192.168.170.251 Bcast:192.168.170.255 Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.170.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
192.168.170.0 0.0.0.0 255.255.255.0 U 2 0 0 eth1

There is now way of tearing down the wireless connection but to either push the radio-switch on the notebook or disable wireless in NetworkManager, but neither is desired - I simply want to disconnect from a network, but not disable the networking at all.

This situation is far from odd, when I go to the meeting room I use wireless, but at the desk I use wired networking.

Can you tell what kind of laptop do you have? What HW network do you have?

Thanks,
Peter

Here is a screenshot which demonstrates the problem. The network-manager UI does not include option disconnecting wired nor wireless network connection. These should include disconnect option.

Thanks for the comprehensive report. I agree this is a usability issue. I will mark this as confirmed...

It seems to me that this issue has been solved in Ubuntu 9.10 Karmic, isn't it?
