A code for every room, desk and visitor.

Staff, visitors and people who left, all on one password.

Staff, visitors and each room or desk get their own code.

The password has been on the wall for two years. People who left are still connected, and nobody can tell who is who.

One code for staff. A visitor code that ends when you say. A code for each room or desk if you want one. Each code sets how many devices it allows.

Someone leaves, so the whole building reconnects.

Change one code. Everyone else carries on.

To lock out one person, you change the password, then type the new one into every laptop, phone, printer and TV in the building.

Press New code on that one desk or room. Everyone on the old code is signed off, and every other code keeps working. Or pause a code for a while.

The waiting-room TV, or one big download, slows everyone.

TVs and big downloads get a fair share, not all of it.

One screen streams all day, or one laptop pulls a huge update, and the whole office waits.

Set a speed by kind of device, like TVs at 4 Mbps, and a daily data amount per device. See each device's maker, kind and data used.

Anything opens on the church, clinic or office Wi-Fi.

Honest note: a VPN can still get around it.
