Oscar Medellin writes in with a reasonable request. After setting up a guest network using his Apple Wi-Fi base station that was paired with using Timed Access Control to limit his kids’ access to the Internet, he found that they couldn’t print via Wi-Fi.
How can I configure their computers or my AirPort Extreme to print wirelessly using my Wi-Fi network while still using the Guest Network?
Unfortunately, this is one of the tradeoffs with guest networking. Not all companies’ Wi-Fi routers restrict printer access, but Apple only allows a kind of tunnel-to-the-Internet. Those connected to the guest network when you have Wi-Fi security enabled also can’t view each other’s network traffic, even with tools designed to sniff around.
