Hi,
i suggest to implement feature, for every hotspot user, additional field “expires on” which is date/time, when this time happens, user should be automatically disabled.
should be very usefull for lot of cases (caffe bars, monthly subscribers etc.)
Wonder how hard it would be to impliment a free-radius type server right on the router?
We use radius to auth hotspot users. Gives you the option of having time limits and oodles of other things.
