Labtop unable to locate home wifi network

For the longest time, my laptop is unable to locate my home Wi-Fi network. I have to use an ethernet cable to get on the internet. Figured it was an issue with my laptop. But if I take my laptop with me on vacation and use it at a hotel, it locates and connects to the hotel Wi-Fi just fine. So my issue must be with my comcast account, but I am not sure where to look and what to do to fix it. My cell phone, home cameras and amazon firesticks all locate the wifi fine, but not my laptop. Kind of tired of using the ethernet cable. Where do I look to resolve this?
