Suse 11.1, HP D530, Linksys WMP54G, NetworkManager running, Knetworkmanager used to configure WPA connection to router. The wireless connection is established but within a minute or less it stops working and the connection degrades and disconnects.
Sabayon linux Live easily establishes connection and retains it indefinitely.
I’ve tried installing KWiFiManager, and I’ve run script collectNWData.sh and started tracking things down this way. I must be doing something wrong. It can’t possibly be this hard for a distribution that has so many other sophisticated aspects.
Did you go through Yast->Network->Network_config and make sure ivp6 protocol is off and network management is clearly set to “handled by NetworkManager / Not default” as this can cause problems when using network manager.

You should also look at the dmesg output to see why it is disconnecting. I
suspect that card has a Broadcom chip. If so, please post the output of
grep b43 returns nothing. I’ve also checked Yast and changed the configuration to DHCP IVP4 only. It was IVP4 and 6. Then I start NetworkManager and knetworkmanager, start the wlan. It takes 15-30 seconds, shows the signal strength as full, quickly decays and stops. I think I’ve set it as techwiz03 describes. The puzzling thing is that it works fine with Sabayon.
Strange, I’ve just started a job which has a wireless network which I have to connect to. I have the same symptoms you describe, using knetworkmanager with WPA. However, my wireless hardware is different to yours: Intel Corporation PRO/Wireless 2915ABG (ipw2200 driver). I’ve compared the connectivity behaviour with Windows XP, and not experienced any problems. I suspect its a NetworkManager issue. Like you describe the signal level appears to drop, then if I do ‘ifconfig’, I see that I’ve lost the IP address as well. The best I’ve been able to do is to configure it to autoconnect, so that it picks up the connection again periodically.
BTW, I’m running openSUSE 11 with NetworkManager-0.7.0.r3685-7.4 installed.
on Network Settings tab “Global Options” select “User Controlled with NetworkManager”
on tab “Hostname/DNS” Select “Change Hostname via DHCP” and “Write Hostname to /etc/hosts”
Then you can use KNetworkManager to setup the connection.
The wireless has been working for several hours without interruption. Once again the Linux community has performed its usual magic. Thanks all!
