I had a friend who told me that TeamViewer 9 suddenly stops working. I found a fix for her. She said that someone was connected to the machine and he was working and it suddenly stopped. The error message it gave is that it had network problems connecting and failed to reconnect. Nothing had changed
If you have Verizon wireless you know that they are perhaps the best network, but the worst at features for the money. However they are finally catching up, and that is appreciated for those of us who have a Verizon device. I had a friend give me a Verizon iPhone so I have kept it.
