Just picked up a 1522 to replace an aging Netgear AP. Using the latest firmware 1.40, I find that it is quite feature-robust, but I would strongly recommend an enhancement for scheduling.
Currently, schedules are set as either all on or all off. If however, rules had the parm added consisting of the connected device's MACID, then the admin could easily set schedules for access via the AP when using MACID filtering as part of security.
In my particular case, this would make it super easy to setup schedule rules to allow (in this particular case) my kids iPod access to the network & wan only during specified days and times, while still allowing my laptop access. I think this would make the schedule feature very powerful in both the home and workplace.
