Whenever you DIRECTLY connect a mobile device to the MPW unique wi-fi signal, you disconnect from your home network wi-fi, because you are now on a different network…Tthis is normal. BUT, you can be connected to BOTH if you follow the directions for concurrently connecting the MPW to your network. Tis all explained in the complete user manual you need to have. Once connected this way, you access the MPW through your home wi-fi as you did before you got the MPW. From this point on, every time you want to use your MPW at home it will re-connect to the home wifi and you have both MPW and home network (and internet) connection. The only time you would connect the NPW to it’s own wi-fi signal is when you are away from home.
If your MPW ever looses ability to connect to home network, just set it up that way again.
