Question [Q] ICS, Viber, Wifi

I am an avid user of the app "Viber" However when I'm using it my wifi keeps disconnecting & dropping the call, only to come back moments later

Is there any way to fix this problem?

I'm not sure if it's an ICS or Viber issue.

I'm using a Huawei ideos x5 handset with ICS 4.03 v2.
