ipw3945d

If you're looking for a reliable way to control and configure various aspects of operating hardware, then ipw3945d is the program for you. This regulatory daemon is specifically designed to ensure your device operates in compliance with various regulatory agencies. With ipw3945d, you'll have everything you need to control which channels are allowed to do active/passive scanning, the transmit power levels, which channels are allowed to be transmitted on, and support for IEEE 802.11h (DFS and TPC).

The best part about ipw3945d is how easy it is to use. Once you load the ipw3945 module, the daemon will be spawned from within the modprobe.conf or udev scripts. However, there are instances where you might encounter problems with this method. For example, if your device is probed before the module is loaded or if there is a delay in the module load, it can cause issues.

Luckily, ipw3945d supports the '--timeout' parameter which lets you specify how long the daemon should look for the driver before giving up. The default value is 0, which means it will exit immediately if the driver is not found. A value of -1 will result in the daemon waiting forever. Any other value will specify the number of seconds to wait. The daemon will poll the system once per second looking for the driver's sysfs entries.

Overall, ipw3945d is an excellent software choice for those looking for an easy and reliable way to control and configure their hardware while ensuring compliance with various regulatory agencies.
