How to provide reliable WiFi?

• Get and pay a system administrator
• Understand that reliable WiFi is not the same as having an Internet Connection.
• Understand that Computer Networks are complex and so are your artists and your audiences needs.
• Understand that you might need seperated networks for your artists and your audience/visitors and potentially even more.
• Make your system administrator document their setup. Not to get rid of them but so that you can have it fixed when they move on to another employer.
