I just began to work with wireless connections in my job, and I could not make KNetworkManager to connect, the program shows the wireless signals and everything is fine until then, after saving and connectng to the wireless provider… nothing happens!!! what is missing? On the other side, if a work with GNOME, the wireless connection works just fine, but I haven’t been able to enable the software update utility.
Also, I was able to set Firefox up to work with my proxy (http) but both, Pidgin and Kopete do not work. Again, what am I missing?
Thanks in advance.
N.B. KNetworkManager, Pidgin and Kopete work just fine when I connect with the ethernet connection.
In my case, both of my laptop’s have Intel wireless, with support right in the kernel [and recent KDE4 testing was on an Intel Wireless Pro 5300 AGN].
But although the hardware network wireless driver is already in place when I was testing the openSUSE-11.1 KDE-4.3. liveCD, and also testing the openSUSE-11.2 milestone-6 liveCD with KDE-4.3, I noted Network Manager in the lower right corner did not work well with wireless.
In both cases I ended up going to YaST > Network Devices > Network Settings and
 acknowledge the warning about NetworkManagement controlling the Network
 under Global Options Tab select the “Traditional method with ifup”
 disable ipv6 (it will ask for a reboot, don’t do that now)
 Overview Tab - select your wireless card and select edit. Go for the default settings except as I noted below
 while in Edit Select “next”
 Under Network Name ESSID select scan network, and then in drop down list select your SSID
 Select your authentication mode (in our case it is WPA-PSK)
 Enter your passphrase
 Select Next
 Select OK
 You may get a notification from Network Management that it is disabled.
And wireless then works. Also, next time you reboot ipv6 will be disabled but hopefully you do not need to rush that reboot. Disabling ipv6 is just a performance tuning measure.
But as noted, you may prefer to install wicd.
Until KNetworkManager is sufficiently mature for KDE4, many wireless “gurus” are recommending one instead use “wicd” for openSUSE. There is guidance here: Wicd - openSUSE
