My facetime keeps disconnecting

Hi,

I Facetime my girlfriend on a regular basis and for months now, I have been experiencing frequent disconnections with Facetime.

Despite both of us having strong Wi-Fi signal at home, our Facetime session keeps freezing with the word "Reconnecting...".

It is so frequent that every night, we expect Facetime to fail 3-10 times.

Any solution or is this a buggy feature of facetime?
