Not seeing this problem reported elsewhere in the forums. fresh install of kde mint 5, I can get wifi up in a couple clicks. Once I update the system, network manager reports that there are no wireless services/signals. Manually add the ssid, it finds it but shows it as having no signal. I try to connect to it and it just dumps saying it cannot connect. I've reproduced this on three machines now and since there is no mintwifi.py, I can't post any output from that command.
I only have wifi, there is no option for me to "plug in".
