A weird wifi behaviour after the upgrade to 12.2

Hi guys,
I updated to OpenSuse 12.2 recently. I have extremely unstable wifi since then. Network manager works weird. I would like to ask you for a help. Here is all the information I am able to gather:

# dmesg | grep b43-phy0

   16.741045] b43-phy0: Broadcom 43225 WLAN found (core revision 23)
   28.852532] b43-phy0: Loading firmware version 508.154 (2009-08-18 00:58:22)
  107.635879] b43-phy0: Loading firmware version 508.154 (2009-08-18 00:58:22)

Networkmanager on system tray shows no wifi access points on the right side.
I have to enter KDE Control module and ADD new connection with the WPA password.
For few seconds I have nice system tray icon everything looks promising.


# /usr/sbin/iwconfig

          RX bytes:173978 (169.9 Kb)  TX bytes:107216 (104.7 Kb)

The WIFI system tray icon then changes, sometimes I can’t ping even AP:


# ping -c 5 192.168.0.1

PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
From 192.168.0.106 icmp_seq=1 Destination Host Unreachable
From 192.168.0.106 icmp_seq=5 Destination Host Unreachable

--- 192.168.0.1 ping statistics ---
5 packets transmitted, 0 received, +2 errors, 100% packet loss, time 3999ms
pipe 4

If I am lucky, pinging AP is OK.
AFTER I succesfully ping AP I can ping outside and I have the full connectivity.
Sometimes there is a big packet loss.
If I try to ping outside directly, I have no connectivity.

If I enter KDE Control Module and try to EDIT the connection a message pops out:
“No agents were available for this request.” The password is missing!!
If I enter the WPA password again I loss the connectivity to AP completely.
I have to remove the whole setup and ADD a new connection again.

On startup, it never connects to wifi automatically.
I does not list saved connections on the right of the Newtwork Manager.
I have to enter password in KDE Control Module again.

If I log in a new user account all network work beautifully. I was thinking about moving to new user and deleting the old account, but it would be pain to be sure I move all the settings. I worry I’d mess up something.

Thank you very much for any help or suggestions in advance

PS: There is one more upsetting problem. On every login I got a message: KDE Daemon crashed unexpectedly.


# dmesg | grep kded4

  114.536950] kded4[1674]: segfault at 0 ip           (null) sp 00007fff32626c48 error 14 in kdeinit4[400000+c000]

I have discovered that KDE Daemon crashes are related to KDE Network Manager dysfunction:

Does anyone have helpful ideas?
Thank you in advance

I have gone around the problem and switched to the Gnome nm-applet. It works without any problems. I have a stable wifi connectivity and KDE Daemon crash does not show up any more. Here is helpful howto: openSUSE starter: Step 2. Need mobile broadband? Use the GNOME applet

happy you got it working…sorry there was no help from the
others…(so many here don’t use GNOME…and . . .)
