Not sure, but maybe you can do something with the Travelmate package installed on your WRT3200AC?

# travelmate, a wlan connection manager for travel router

## Description
If you’re planning an upcoming vacation or a business trip, taking your laptop, tablet or smartphone give you the ability to connect with friends or complete work on the go. But many hotels don’t have a secure wireless network setup or you’re limited on using a single device at once. Investing in a portable, mini travel router is a great way to connect all of your devices at once while having total control over your own personalized wireless network.  
A logical combination of AP+STA mode on one physical radio allows most of OpenWrt supported router devices to connect to a wireless hotspot/station (STA) and provide a wireless access point (AP) from that hotspot at the same time. Downside of this solution: whenever the STA interface looses the connection it will go into an active scan cycle which renders the radio unusable for AP mode operation, therefore the AP is taken down if the STA looses its association.  
To avoid these kind of deadlocks, travelmate will set all station interfaces to an "always off" mode and connects automatically to available/configured hotspots.  

## Main Features
* STA interfaces operating in an "always off" mode, to make sure that the AP is always accessible
* easy setup within normal OpenWrt environment
* strong LuCI-Support with builtin interface wizard and a wireless station manager
* render the QR-Code of the selected Access Point in LuCI to comfortably transfer the WLAN credentials to your mobile devices
* fast uplink connections
* support all kinds of uplinks, incl. hidden and enterprise uplinks (WEP-based uplinks are no longer supported!)
* continuously checks the existing uplink connection (quality), e.g. for conditional uplink (dis-) connections
* automatically add open uplinks to your wireless config, e.g. hotel captive portals
* captive portal detection with internet online check and a 'heartbeat' function to keep the uplink connection up & running
* captive portal auto-login hook (configured via uci/LuCI), you are able to reference an external script for captive portal auto-logins (see example below)
