First off, I did a search for this but apparently I didn't word it correctly and found nothing on this topic.

My main question is this. Since the area has to be perfectly level when you calibrate your IMU, can this be done indoors, like on a very level kitchen counter? If so, do I need to unplug my router so my WiFi will not interfere with this procedure?
Other than that, I guess I could take a small piece of plywood with me to my flying site and a level to make sure it is flat.
Any other suggestions would be greatly appreciated! Thank you!
