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 wlan0 IEEE 802.11bg ESSID:"sunreen" Mode:Managed Frequency:2.412 GHz Access Point: 64:70:02:CE:FC:44 Bit Rate=1 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=70/70 Signal level=-35 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:3 Invalid misc:3 Missed beacon:0 # /sbin/ifconfig wlan0 Link encap:Ethernet HWaddr 18:F4:6A:0C:19:0E inet addr:192.168.0.106 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::1af4:6aff:fe0c:190e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:512 errors:0 dropped:0 overruns:0 frame:0 TX packets:689 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 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: segfault at 0 ip (null) sp 00007fff32626c48 error 14 in kdeinit4[400000+c000]
