Can we open our same Upwork ID on different laptops with different or same internet connections?
You can as long as it is only ever you, yourself, and never ever another person.
If you share your account or let someone else use it, you might find yourself suspended very quickly.
So as long as it is 100% you and only you, there is no issue with you accessing Upwork from different devices and different Internet connections.
