TPControl connects to an AMX NetLinx Master using a permanent IP socket i.e. the operating system opens an IP port based on TPControl raising a request to the operating system to open the relevant ICSP (1319) IP socket. The devices operating system handles all management of the connection with the WiFi WAP/router, TPControl simply asks the operating system to form a channel of communication - the IP socket.
Other applications that you may be used in the comparison, such as web browsers or email clients, work slightly differently in that they open an IP socket (again handled by the operating system), request the information they need and then close the socket. If there are brief connectivity problems, you tend not to notice them other than perhaps the web page taking a few more seconds to load and similar to email. In the case of TPControl, we highlight the connectivity issue with the 'Not Connected' dialogue, based on the operating system losing/dropping the IP socket and ultimately the device losing connection to the AMX master.

So, if you are experiencing frequent dropouts ('Not Connected' messages) this is highlighting that there is an overall connectivity issue - not a problem with TPControl.

There can be common factors contributing to this:
- AMX Device ID: are you sure you are using a unique AMX Device ID when connecting to the AMX NetLinx master? If you have other touch panels or devices that use the same AMX Device ID that you have configured, then this will result in essentially each device conflicting in connection to the NetLinx master.

- WiFi issues: have you performed an audit/test of the usage of WiFi in your location? i.e. you may find that other WiFi WAPs/Routers are using the same or similar radio-channel that your WAP/Router is using, which can result in degraded WiFi performance.

- iPad Network Settings - Reset: We recommend, particularly after an iOS update, to reset the Network settings for your Apple device, and re-pair it. This is in part due to problems with devices maintaining WiFi connections after iOS upgrades. To do so, go to: 'Settings -> General -> Reset' and select the 'Reset Network Settings' option, followed by the 'Reset' prompt. This will remove all iOS maintained WiFi connection settings in the device.

NOTE: you will need to know the details to re-associate/pair the device with your access point (i.e. the SSID/Passphrase etc). Once the device has reset, and you have reconfigured the WiFi connections in 'Settings -> WiFi', review the connectivity problem you were experiencing to see if it is now resolved.
