Here is a list of steps you can take to resolve your WiFi connection dropping when you move rooms:

1. Check your router and look for any unsecure or conflicting connections.
2. Check your router settings and determine whether or not it is set up to limit or restrict the distance you can be from the router.
3. If your router has settings for roaming or switching, turn them off.
4. Check for any existing wireless networks that could be interfering with yours.
5. Move your router and reposition it to a spot that has better reception.
6. Ensure that no large objects or appliances (like microwaves) are creating interference.
7. Check for any available firmware updates to your router.
