Connectivity Issues with new routers

I have several android apps that connect to a main kiosk run on a all in one pc.  Recently all newer routers do no allow my kiosk to connect to the android apps.  At first i thought it was just tri-band routers as I was able to still make a connection with dual band.  Now though the new dual band routers I got have also stopped allowing the connection.  I have tried every configuration I could think of on the routers and turned off all firewalls but now luck.

Any suggestions would be welcome!
