I manage RHEL servers at work. I configure interfaces manually by jiggering around with the scripts in /etc/sysconfig/network-scripts.
But that's not what I'm asking about. I just want to provide some bona fides.
My Toshiba laptop has been happily running Fedora since F13. I used preupgrade to seamlessly upgrade to F15, and a few months back to F16.
A week or so ago, the wireless link began to flake on me. KDE Deamon would request access to the wallet, and I'd be asked to type in the "secret" for my wireless network. I couldn't actually get this to work, so I'd reboot. This became more and more common and last night I thought I'd remove and reinstall the connection.
Since I knew how to muck with those config scripts . . . how hard could it be?
Well, two concatenated words: NetworkManager. Wrapped around my laptop's network devices like Borg Implants around Jean-Luc Picard's amygdala.
In /var/log/messages I see my laptops's wireless interface get recognized, assigned wlan0, and then declared "managed" and made unavailable.
I've tried using NetworkConfiguration GUI, but I just can't get wlan0 to the point where it can find my home network.
So . . . what's easier? Learning the convoluted muck of NetworkManager, or uninstall it and try to get it working manually?
The only "gotcha" is that this is a wireless connection, and I suspect that NetworkManager is providing the "hey, there's your wireless network, I'll take care of connecting and providing the right keys" service.
