Our current WiFi APs (D-Link DAP-2553, and Linksys WAP4400N) are the kind available from the local Bestbuy store and are for home users I believe. They will intermittently shut down by themselves. They are cheap and at low end.
In our office the WiFi is for mobile devices and a small number of laptops. Even the utilization is not high but we just cannot stand the unliable AP shutting down by itself. Can you recommend some higher end of WiFi APs with more reliability?
