Dont waste your time, just throw it in garbage and buy new one ! TP-link are not bothered to take out the old firmware which cause all this issue in the first place from there website nor are welling to fix the issue as you can find it only in a dropbox link (seriously ?) so that's my recommendation to you, buy a better printer server PS: i struggle with this peace of crap for almost a week then manage to make work, purchase a replacement so the moment it start bitching to throw it out of the window.
