I have been having a problem Norton WIFI Privacy ever since it came out. I have submitted the problem to tech support many times over the past year now and the problem still exists. I have problems using Norton WIFI Privacy on XfinityWIFI, Stop & Shop WIFI, MacDonald's WIFI. Usually the web browser or application just hangs with no message. When there is a message it is usually something about a proxy server being not found. This occurred on Windows 7 & 10, several Android 5 phones.
Since Norton is marketing Norton WIFI Privacy as THE solution to the latest WIFI vulnerability issue, they better get their act together and make sure Norton WIFI Privacy reliably works on ALL types of public networks.
