I am installing a wireless network for a coffee shop. They only have one Internet connection and one network, with one PIX 501 firewall and an 1100 WAP. I want to make the guest account as easy as possible to access, so I'm using open authentication, etc. That's the easy part. What I'd like to do is separte the guest's from the internal network. They don't have any computers on it yet, but they want to add some later.
What would be the best way to make two separate network and keep the internal network secure? Of course, they want to spend as little money as possible.
Any suggestions would be appreciated. Thanks
