I was having problems with my WIFI disconnecting and not reconnecting for long periods of time. Here is what I have done; first I changed my WIFI settings (Comcast Business Class Router) on the 2.4Ghz to include (b) b/g/n. I was still having some issues with Android telling me bad IP address etc., so I reserved my IP address for the scan tool in my router. I have now gone a full day and a half with full connection and even turned my WIFI off and back on to check it. So far so good.
