we are suppose to reconnect SSID to use Internet.

Ok. Very likely it is not RUKUS problem case.
So U have to reconnect your WLANs after your APs lost GW connectivity. 
I guess Your AP are tuned to cut off WiFi clients when no gateway connectivity happens. 
U may try to find & correct appropriate settings in AP WEB - Wifi will be still works but will no internet access for clients at all untill no gateway connectivity...
Also U d better check configures on APs autentification optoins (hotspot portal? guest access portal? RADIUS? 802.1X?) and L3 routing problem (gateway connectivity) in your ISP networks.

I can say its not the issue or L3 routing as the devices in LAN are able to use Internet without interruption.

I agree if so. APs autentification optoins?

Check DHCP (ip conflict)
Check would it ON\OFF:
-Inactivity timeout (for idle clients). 
-Access control and User traffic options.
-Tunneling have (to be OFF on APs).
-Wireless client isolation (have to be DISABLE on APs).

Renew softwares on APs...
Tune WLANs again from default.
No more ideas..
