I apologize upfront if I missed something but - I noticed since applying the 4.2 updates from the test repository that knetworkmanager no longer works for me to connect to wireless. Wired networks appear to work fine. The only way I've seen to get around this is to install NetworkManager-gnome. When this is installed knetworkmanager works fine (but isn't really needed since NetworkManager-gnome is installed.... duh...). I did some searching and found: http://www.osnews.com/story/20758/KDE_4_2_Progress_New_NetworkManager_Plasmoid_Coming which looks like the old knetworkmanager is on the way out (or with 4.2 appears already gone... ;-) ) The new plasmoid isn't going to be distributed until 4.3 but apparently is available to test with now. What's the current direction on this? Use NetworkManager-gnome until 4.3, make the plasmoid available to use or fix the old knetworkmanager? That said, so far I'm really pleased with 4.2 - things appear to be working fine!
