Hi, I am using Debian Squeeze with kde 4 installed. My problem is that I am trying to use wireless without success although I can get the router's name, signal strength and encryption type on the kde network settings application.
Could you please tell me what is the purpose of user groups and how they affect an OS's security on the network including the internet? I beg your pardon for asking this question, but I am concerned that if I do something wrong I might unwittingly expose my data.

Permissions and groups is a very broad topic, but I'll try to give you a short version as it pertains to your situation. Having a netdev group allows any user in that group to access devices and files for network configuration that are normally reserved for root. It's a safer alternative than running as root to access the devices/files you need. The group along with root has access which limits what certain users on the system have access to.
There is also a typo in my above post which I have corrected.
So, effectively, you are telling me that the system is refusing to use the wifi because some network configuration files are not accessible for my user name.
Do you have an idea which files are these? I should think, if as a normal user with my limited account, I can view these files with a text editor, then it should mean, the problem is caused by something else.
Please, excuse my concern for being very cautious: I migrated from MS Windows to use GNU/Linux for security reasons primarily and then for free software.

I am saying it could be the problem, not that it is the problem. I understand your concern, but becoming a member of the group is safer than running as root. Groups are a safe way to allow users access to devices/files as well as restricting access to those same devices/files.
It is no different than being a member of the audio, cdrom, or plugdev groups. Without membership to those groups you wouldn't be able to use sound devices, cd/dvd devices, or pluggable devices. i.e. flash drives.
Good luck.;-)

1. Ensure your user account is a member of the netdev group.
If you still have concerns and would like to remove your user from that group, just issue usermod again with the groups you prefer to stay a member of.
