I left when RIF was disabled, 2 years ago now or close

Yes, it applies some power-saving settings to both my interfaces, then I lose the connection in the following 10 seconds. I should screencap the commands for all the other settings and prepare a custom script that wouldn't touch my network

Why not Roundcube ?
