FAQ

Is guest Wi-Fi slower?

Sometimes guest profiles are rate-limited. Read your router settings.

Does guest Wi-Fi isolate malware?

It helps separate devices, but it is not a substitute for updates and sensible security practices.

Can guests still reach printers?

Depends on router settings. Some guest networks block LAN access by design.

Should IoT gadgets use guest networks?

Often recommended because many devices update slowly compared with laptops.

Will guest SSIDs slow my main network?

They share the same radio time. Heavy guest use can still affect airtime.

How do I document SSIDs for family?

Print simple cards with names and which devices belong on each network.
