I was running the same laptop, with opensuse 11.1 with kde4.4.4 and networkmanager managing the network. After a few minutes the wifi connection get lost. 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.

(tested with or without IPV6 activated, doesn't change) 2.When the connection is established, browse the net during some minutes (1->15) Actual Results: The connection stops functionning (with any site, and any protocol) The interface begins to broadcast ARP requests to the gw (who is nnn.nnn.nnn.nnn) see tcpdump attached (can no longer see the gateway) Expected Results: The connection should stay alive -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
