Public bug reported: * Case 1: Problem description: Some wifi drivers/chipsets get confused after a while and will fall off the network and then fail to get on again with the normal network manager probings. A root shell and modprobe -rv ipw2200; modprobe ipw2200
References: Windows provides a "repair device" choice in the tray network icon which appears to remove and reinstall the driver Suggested fix: A "repair network device" choice should be available through network manager * Case 2: Problem description: RFKILL switch kills wifi driver permanently. Suggested fix: See above for workaround. A setting somewhere to automatically reinstall the wifi driver after unkill occurs would be nice. * Case 3: Problem description: USB devices keeps Laptops from reaching low power states for any significant time. My current laptop has a builtin 3G device and a builtin bluetooth device. Both are on a USB bus. According to powertop these rank among the top wake-up-causers on the system. Suggested fix 1: powertop suggests "suspending usb". Not quite sure what this entails but unloading the USB stack seems one likely solution. A desktop device manager to do this would be nice. Suggested fix 2: Powertop further suggests unloading the bluetooth and 3G device USB drivers. This normally requires root access and knowledge of the driver names. This is a less drastic way to realize almost the same goal as in fix1. A desktop widget is needed. * Case 4: ... Once the desktop bus interface to manipulate the usb stack and wifi drivers is realized it's not all that strange to supply a "rfkill" software switch in the network manager applet that lets us do rfkill on the wifi and bluetooth but keep the 3G device going for example.
