I have noticed some weird things, the connexion is done well and quick (a few seconds) if I look to the speed before it connects it shows me a nice 54mbps, but once the connexion is established the speed falls to 2mbps ! the iwconfig shows this : lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11abgn ESSID:"tagada" Mode:Managed Frequency:2.412 GHz Access Point: 00:18:F6:72:3E:00 Bit Rate=1 Mb/s Tx-Power=15 dBm Retry long limit:7 RTS thr : off Fragment thr : off Encryption key : off Power Management : off Link Quality=70/70 Signal level=-36 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 pan0 no wireless extensions. /etc/resolv.conf : ### /etc/resolv.conf file autogenerated by netconfig! # # Before you change this file manually, consider to define the # static DNS configuration using the following variables in the # /etc/sysconfig/network/config file: # NETCONFIG_DNS_STATIC_SEARCHLIST # NETCONFIG_DNS_STATIC_SERVERS # NETCONFIG_DNS_FORWARDER # or disable DNS configuration updates via netconfig by setting: # NETCONFIG_DNS_POLICY='' # # See also the netconfig(8) manual page and other documentation. # # Note: Manual change of this file disables netconfig too, but # may get lost when this file contains comments or empty lines # only, the netconfig settings are same with settings in this # file and in case of a "netconfig update -f" call. # ### Please remove (at least) this line when you modify the file! search tagada.home nameserver 192.168.1.254 I have copied the .ked4/share/config/networkmanagementrc and ked4/share/apps/networkmanagement/config/* from my old disk (to ensure that was not a problem from kde in the new install.

Does this problem still occur in 11.4 ?
As far as I have observed no. On the other hand with 11.3 and a 2.6.39 kernel either. If you need more info (traces etc) just inform me as I am not always on the site where I observed the crashes, and I have changed my laptop in January this year. I will have to test it again. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
