Hellow jean don't be silly.
Every problem has a solution so don't worry.
I searched a little bit online and got this.
Do the following steps,
"If you find your powerbot with this issue, try checking your wireless router’s settings. You might need to reset the Wi-Fi network to troubleshoot the issue.
First, identify the source plug of the router and unplug it. Wait for at least 30 seconds before plugging on. Then reset the router and try reconnecting it with the powerbot.
If this still does not work, you might need to reset the wireless antennae of your powerbot. For further intricate details, ask for expert assistance"
