On Xubuntu Karmic I access the net using a RaLink RT2561/RT61 802.11g PCI and a WiFi network that uses WPA/WPA2, EAP-TTLS, PAP security. The network sometimes "hangs" and Gnome's network manager usually reconnects automatically. Every once in a while (I'm unable to recreate it) the network-manager seems to hang and a reboot is required to get it working again.
I am using Kali Linux 1.0.6. Recently I have disabled Network Manager and configured my system to connect to wireless network through Terminal by editing /etc/network/interfaces and running wpa_supplicant.
Now, I want to switch back to Network Manager UI but I am unable to see any wireless networks. It is saying device not managed under Wireless Networks.
