Description of the problem:
I have Belkin wlan card F5D6001, which is supported by Realtek's rtl8180 driver (according all searches I performed).

The driver loads ok, and initializes the card (according syslog and messages).

Here I have no wireless access point, so no network using the wireless card, only wired, if I need to.

It doesn't matter if I have wired connection or not, or if it was connected before that or not - if I go to Administration/System/Network, and un-check the checkbox in front of the wireless card to disable it, the system hard freezes. No ssh to it (if wired connection is present), no keyboard or mouse activity, no Ctrl-Alt-Backspace or Ctrl-Alt-F1-6 to switch to text mode. The only solution is power-cycle.

Here are the relevant part of /var/log/messages when the freeze happens:

/var/log/messages:
Oct 1 18:34:18 mubuntu kernel: [ 668.897833] rtl8180: Setting SW wep key
Oct 1 18:34:18 mubuntu kernel: [ 668.946479] rtl8180: Bringing up iface
Oct 1 18:34:18 mubuntu kernel: [ 669.155018] rtl8180: Card successfully reset
Oct 1 18:34:18 mubuntu kernel: [ 669.492580] ADDRCONF(NETDEV_UP): wlan0: link is not ready

In /var/log/syslog there is nothing interesting, the last message was 4 minutes before I invoke the freeze.

What else can I provide in order to help diagnose the problem?

Cheers
Sunny

Btw, blacklisting the r8180 driver, and installing ndiswrapper and the Realtek driver for RTL8180 works OK. You only need, after installing the realtek driver in ndiswrapper to invoke:
# ndiswrapper -d 1799:6001 net8180
to make the driver to recognize the card.

Thanks for taking the time to report this bug and helping to make Ubuntu better. It would be helpful if you could provide the numeric PCI ID of your network adapter. You can obtain this information via 'sudo lspci -vvnn'. Thanks in advance.

Now that you have provided the PCI ID of your hardware I am going to set the bugs status to "Triaged". Please do not set bugs to "In Progress" as that means that someone is working on fixing the bug which is not the case as far as I know.

I have a very similar problem. I got a wlan card with rtl8180L chipset. If I try to get an IP via DHCP, the system freezes and the numlock and capslock leds start to blink. I am using ubuntu gutsy.

I can do some things with the card. It is possible to scan for cells, and it does find some. It is also possible to assignt an access point to the card. I can set a wep key. If I try to get an IP from my router via DHCP, everything freezes.

Cheers,

sorry, I think this isn't the same bug as yours. If I turn off wep, the card works fine.
I apologise for the trouble, I am causing

sorry for bothering, as you can read here https://bugs.launchpad.net/ubuntu/+bug/152102 , I managed to fix the problem by blacklisting r8180, too.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

I don't know whether I'm at the right adress with posting this here, anyways:

The release candidate of Intrepid Ibex starts fine with the Belkin F5D6001, no freeze so far. The WLAN - Card is recognized properly out of the box, the only thing to mention is that the connection signal reported by the nm-applet is awfully low. In Hardy, I got 75% with the above mentioned net8180 windowsdriver and ndiswrapper, Intrepid only shows 5 - 10 %.

The good thing: no freeze :]

Please feel free to tell me if you need further informations.
Greets,
