Connection problems can occur. Methods for resolving and preventing these problems depend on the tool used.
Some common problems related to KNetworkManager include the applet not starting, a missing VPN option, and issues with SCPM.
The KNetworkManager applet should start automatically if the network is set up for
NetworkManager control. If the applet does not start, first make sure
that the package NetworkManager-kde
is installed.
If the desktop applet is installed but is not running for some reason (perhaps you quit it accidentally), start it manually. To start the applet manually, run knetworkmanager from a command prompt.
NetworkManager, applets, and VPN support for NetworkManager are distributed in separate packages. If your NetworkManager applet does not include the VPN option, check if the package with NetworkManager support for your VPN technology is installed.
VPN support is included in following packages:
NovellVPN—package
NetworkManager-novellvpn
OpenVPN—package
NetworkManager-openvpn
vpnc (Cisco)—package
NetworkManager-vpns
You are probably using SCPM together with NetworkManager. NetworkManager is not currently able to work with SCPM profiles. Do not use NetworkManager together with SCPM when SCPM profiles also change network settings. To use SCPM and NetworkManager at the same time, disable the network resource in SCPM configuration.
Problems related to KInternet include the applet not starting or not all devices appearing.
If KInternet does not start automatically, first make sure
that the package kinternet is
installed.
If KInternet is installed but is not running for some reason,
you can start it manually. To start it manually,
run kinternet from a command prompt.
