Here's the scenario:
We have an office wireless network with which 10 to 20 of our guests connect every day using a variety of client devices, including laptops (Windows and Mac OS X), iPads, and smart phones.
We are not responsible in any shape or form for our guest's wireless configurations. In many ways, we're like a coffee shop. People sit down at one of our tables with an endless number of wireless configurations and expect to connect to our wireless network.
We've deliberately left our wireless access points configured with WEP for two reasons: 1) We have hundreds (if not thousands) of clients with our current SSID saved with the WEP security protocol. 2) Some of our clients have really old laptops.
Time to switch over to WPA2 long overdue. Here's the question, how much pain will our guests experience with their client devices?
Do we consider implementing a brand-new SSID to force our guest's client devices to create (and save) and brand new connection?
