I'm working on a project that needs to constantly be in touch with an AP. If the current AP goes down, we need it to pop over to a new one in very short order, (minute or less). We were planning on using the built in scanner, but the interval only goes down to 5 minutes. Too high an interval. Is there another available out there or is there a conf file that I can edit on the N810 to set this for a much lower scan rate?
