Hi. My 3200 is same. After a few days or, if I'm lucky, weeks the router will stop functioning properly. Once that happens, very commonly a hard power cycle is required. I tried setting it to do auto reboot a little over a week ago; the problem frequency went to failing every single day, about 12 hrs after reboot. Finally even manual reboot couldn't get my internet back. So auto reboot made it worse, or at least didn't make it any better. It's possible that some phenomenon that involves my other devices are in play because I had to power cycle access point also. I went back to just leaving the router run normally and power cycling when it crashes. My problems after auto reboot were typically WiFi failures, just fyi.
