Hi @Micheleboulton
Have you tried forgetting the network? Settings ? network > Scroll to the VM network then press the menu buttonon your remote. Then press the button above the fast forward symbol and choose Forget network.
You should also have an HDMI extender cable with the firestick. (picture with the hdmi extender highlighted at the bottom) Plug the firestick into that as it moves it further away from the TV so helping to cut down on interference.
Even though it worked OK at your daughters house you could also try factory resetting the firestick.
You can do this by either
Pressing the Home button on your remote and then going into Settings. Then select My Fire TV, scroll down, and click Reset to Factory Defaults. Finally, click Reset when the pop-up message appears.
Or
Press and hold Back and the Right side of the navigation circle together for 10 seconds. On the TV screen, choose to continue or cancel the factory reset. If you don't choose, the device resets automatically after several more seconds.
