A device cannot see the Wi-Fi while other devices connect fine
Many smart devices and older laptops only speak 2.4 GHz. If your AP only broadcasts 5 GHz or the bands are merged, those devices are stranded.
Try this first
- 1Identify the device type. Smart plug, scale, older printer, camera? Almost always 2.4 GHz only.
- 2In your AP controller, check that the SSID broadcasts on both bands. With band steering or a single merged SSID, the 2.4 part can be invisible to some clients.
- 3Temporarily create a separate 2.4 GHz-only SSID with a different name (e.g. "office-iot"). Connect the device there.
- 4Put the phone you use for pairing on that same 2.4 GHz network during initial setup. Many IoT apps require it.
When to bring us in
If you have many IoT devices, a dedicated IoT VLAN with its own 2.4 GHz SSID is cleaner. We can set that up without touching guest or office Wi-Fi.
