I've heard most modern routers feature power saving (at night) enabled by default.

When the router reboots the next morning, some setting may be lost.

Modify:

Oh! You're using a USB adapter.

I use BUFFALO myself.

This phenomenon happens quite often.

Usually cause by overheat.

I have no folder modprobe.d under /etc but a empty file modprobe.conf .... not really sure what do do.... create folder and file or edit the conf-file.

Juanito:
edit modprobe.conf and add it to your backup.

I guess the other option is to use the "blacklist" boot code to prevent the module being loaded and then manually "modprobe"  the module with the desired options.
