Gnome network-frontend doesn't show access points

[maestrosys]

Hello,

I have a Samsung NC10 with a Broadcom 4313 WiFi adapter. I have installed the brcm80211 modules (http://wiki.debian.org/brcm80211).
On the netbook LinuxMint Debian is working fine.

iwconfig gives:

Code: Select all

lo        no wireless extensions.

eth1      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any

          Encryption key:off
          Power Management:off
          
pan0      no wireless extensions.

The modules seem to be loaded. lsmod | grep brcm80211 gives:

So I think the nm-tool recognizes access points and the adapter working correctly.
But the gnome-network-manager frontend doesn't show any access points when right-clicking on the symbol in the taskbar.

Some help would be great.

Thank you and kind regards,

Thomas

Disconnect your wired network and try again. Frequently Network Manager will not connect to a wireless connection if there is a wired connection.

I'm not connected to any wired network. But Network-Manager doesn't show access points.

My bad, I misinterpreted this in the nm-tool output.

Anyhow, go into Network Manager, edit the wireless preferences and set IPv6 settings to ignore if they are not. This has helped a number of people.

[maestrosys]

I've set IPv6 to Ignore in network-manger. But thats only possible if I create a new wireless connection by manual SSID input. But it doesn't alter anything.
How can I set IPv6 to Ignore in general?

What I have always suggested to people in the past was about what you have done. Open N-M applet, select the wireless tab, select a connection, select edit, set IPv6 to ignore. That has worked for a number of people and no further questions were ever raised, so I never looked for more. Especially since my wireless was working in the same manner. Is there a checkbox in the applet to make the same settings for all connections? (not on linux at the moment)

[maestrosys]

It works. No idea why a second try was needed.

Now there are left some small issues:
The system crashes when deactivating the wifi adapter via Fn-keys. But not directly after deactivating but after some seconds. Any idea which logfile I could refer to?
Same thing after wake-up from suspend-to-ram. Maybe the same issue?

Cheers,

Thomas

The log file for suspend is pm-suspend.log. Since I can not recall the exact path (something like /var/log/some_path/pm-suspend.log ) it may be easier to use the Log File Viewer GUI.
