Smart device won't connect? Let's find out why.
Pick the device and what it is doing. You will get the most likely cause, the fixes to try in order, and a link straight to the full step-by-step for your exact gear. No sign-up, nothing stored.

This tool points you at the most common cause first, in plain English. It is not a promise that your exact device works one particular way, and it is not a substitute for the maker's instructions. When the airwaves are the problem, no amount of re-pairing fixes it, and that is usually a network job.
Why nearly every "faulty" smart device is really a Wi-Fi problem
Here is the pattern we see over and over. A smart plug, a camera, a doorbell or a robot vacuum stops responding, the app says it is offline, and it looks for all the world like the device has died. You buy a replacement, set it up in the same spot, and a few weeks later you are back where you started. The device was never the problem.
Almost all of this cheap, convenient gear shares one trait: it only talks on the 2.4GHz Wi-Fi band. That band reaches further and punches through walls, which is exactly what you want for a sensor in the shed or a camera on the eaves. But it is also slow and crowded, and modern routers make it worse by hiding both bands under one Wi-Fi name and quietly steering your phone onto the faster 5GHz band during setup. So the device is sitting on 2.4GHz waiting to be found, while your phone is chatting away on 5GHz, and pairing just spins.
Once you know that, most smart home faults sort into three buckets: the wrong band during setup, not enough signal where the device actually lives, and a 2.4GHz band so busy in the evening that the weakest devices fall off. The troubleshooter above sorts your problem into the right bucket and hands you the fixes in the order worth trying, then links you to the deep dive for your specific device.
Common questions
Why do so many smart home devices only use 2.4GHz Wi-Fi?
The 2.4GHz band travels further and passes through walls better than 5GHz, which matters for cheap, low-power gear scattered around a house. So bulbs, plugs, cameras, doorbells and vacuums are almost all 2.4GHz only. The catch is that modern routers hide both bands under one name and often push your phone onto 5GHz during setup, which is why pairing spins and fails even though the device is fine.
Why does my smart device connect near the router but not where I want it?
Because it is a signal problem, not a pairing problem. Many devices pair happily beside the router, then fail once they are moved to a back room, a wall, or outside. The fix is more coverage where the device actually lives, usually a better placed access point or a mesh point, not a new device.
My smart home devices drop off every evening. Why?
That is a congestion pattern. In the evening every screen in your street is streaming and the 2.4GHz band gets noisy, so the weakest devices lose their airtime and fall off first. It looks like a fault but it is airtime. Separating your smart gear onto its own band or network keeps it steady when the airwaves get busy.
Should smart home devices be on their own separate network?
For anything past a handful of gadgets, yes. Giving smart devices their own 2.4GHz name or a separate network stops the router shuffling them onto 5GHz, keeps them steady during busy evenings, and walls them off from your phones and laptops for a bit more privacy. It is one of the most reliable upgrades you can make.
Is a device that keeps dropping off faulty, or is it my Wi-Fi?
Nine times out of ten it is the Wi-Fi, not the device. A single gadget that drops can be signal or a tired battery, but when several drop together, or they all drop at the same time of day, the network is the cause. Replacing the device rarely helps, because the new one lands in the same weak or crowded spot.
When is it worth getting someone in to fix it?
When you have tried the band, the signal and a re-pair and things still will not stay connected, or when a whole home of devices is unreliable, it is usually a network design issue rather than any one gadget. That is the point where a proper look at coverage and network layout saves a lot of guessing, and it is exactly what we do.
