eero Beacon guest network cannot reach devices, cast or print

The checks in more detail

Common complaints are guests who cannot connect, guests who can see your devices, and guests who reach the internet slowly. Make sure Guest Access is on and that the password is at least eight characters. A guest network name that looks like your main one confuses people, so use a distinct name. If the guest network does not appear after setup, restart the gateway eero from the app and wait.

Guest devices are isolated from your own, which also means a guest cannot print or cast to your TV; this is by design. In bridge mode, guest access depends on the router you kept, so configure it there. A Beacon far from the gateway may give guests weaker Wi-Fi. eero lets you see which devices are on the guest network in the app's device list, marked as guests, so you can check that a visitor's phone is where it should be.

If a smart-TV streaming guest is buffering, remember guest bandwidth shares your internet, and pause large downloads on the main network. Parents sometimes use the guest network for children's smart toys and cameras, which keeps them away from computers on the main network. This works well because the guest network isolates devices, but remember those devices cannot be controlled locally from your phone, so check that the device's app works through the cloud.
