I have a number of Raspberry PIs which I set up to connect via wifi to my router by editing the /etc/network/interfaces file and adding the password for my router.
What I wanted was a way of connecting to the Pi without having to configure it with the pwssword for my router. ie make the pi act as a router with a standard password so that my laptop can connect directly or via the router? is this the meaning of a wifi hotspot? i don't want the pi to connect to the internet, just to be able to wifi to it from another machine without configuring it.
