App doesn't work "after a while"

Hi, I'll try to explain my issue more detailed I can.

I've been using Wifi Keyboard for a long time.
Recently I've had to change my router because my new home DSL ("Fastweb", 
Italy) doesn't work with my FritzBox 7390.

I'm actually using a Linksys WAG160N router.

When I receive an IP via router DHCP, the app works fine, but after a few hours 
(or less), the browser can't direct me to wifikeyboard anymore: "impossible to 
connect 192.168.1.xxx:7777" where xxx is the ip address wifikeyboard write in 
my phone to let me connect via browser.

If I delete the DHCP table on router and turn it off for a while and then turn 
on again, it gives me a new (and different) ip address, and the app will work, 
but once again it will work for just 30mins/1hour and will stop working again.

I tried to handle on 7777 port forwarding on router, to uninstall and reinstall 
the app on the phone, nothing worked.

I use Windows 7 64bit
Google Chrome updated to last version
Galaxy S3 with Android 4.1.2
Router firmware is up to date

What can I try to let wifikeyboard work again?

Thanks in advance and thanks for this great and useful app!
