We have several WiFi at our organization, but we only have one where our TC70 devices will be able to connect and send and receive data.

We've noticed that we have devices that were able to upload/download are suddenly not able to do either. When I check the device, I find that it has connected to another WiFi profile and that the original profile is marked with a authentication error and the only way to correct it is to reset the device. Once the device restarts, it is once again connected to the WiFi that the device can upload/download from.
