I've had my Z8 for about 6 months now and always used wifi. I recently moved and had to changed internet providers. Now when I attempt to connect to wifi it says "trying to connect" but will never connect. If I connect via ethernet for a few minutes and then disconnect it the wifi will work great for a few minutes or even a few hours before disconnecting again. I've done factory reset, rebooted the router. Tried with and without ipv6. Any other solutions?
