It stays connected to my Wi fi router ( new updated Apple airport extreme ). I have just tried to run it on the guest network, which didn't work either. We have 2 iPads , 2 iPhones and a iPod, that are on this Wi fi router also.It shows that the Wi fi is enabled also. It keeps losing the connection with the Lennox server. What will fix this problem ? Should I put on its own Wi fi router ? I could buy an apple airport express and run a ethernet wire from the back of the extreme to the express . This problem stops the app in the iPhone/iPad from being used. What can I do ? Lennox and the installer cant seem to help.Sometime it works using the apps and sometimes it doesn't.
