Hi. My name is***** you for your question and the opportunity to assist.
If after the power outage your other devices are connecting to your wi-fi OK
see if you can get the printer connected using this video: https://www.youtube.com/watch?v=kOUA2t7lJlk
Let me know the result please.
I thought your printer wasn't working. I wasn't aware of a sound problem on your laptop?
I'll forward your request to customer service.
