The projector of our local philosophy group has been smashed.

The leads though frequently caused near-accidents, so it was thought a
wireless-based replacement might be a good idea.

Wifi enabled projectors are available but the problem is how to link them
to the laptop that is intended to drive it if we have no hub?

Can we turn the laptop unto a wifi hub for this purpose?

Why not get a short/ultra short throw projector? They can have a throw
of 400mm or less. You can then route the cables around the edges of the
room.
