As of 13 August 2026, AI can only partly improve your smart-home Wi-Fi coverage.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open your router or broadband provider app and record the router model, broadband equipment model, Wi-Fi standard if shown, current Wi-Fi names, security mode and whether separate 2.4 GHz and 5 GHz networks are enabled.
   2. Draw a simple floor plan showing the router, walls, floors, large appliances, problem rooms and the locations of smart-home devices that lose connection.
   3. Run a speed test beside the router and in each problem room, recording download speed, upload speed, latency if shown, device used and whether it is connected on 2.4 GHz or 5 GHz.
   4. Paste the router details, floor-plan description and test results into the prompt, then ask the chatbot to identify which tests distinguish weak signal from broadband, interference or device faults.
   5. Carry out only the proposed low-risk tests first, changing one thing at a time, and record the result in the same rooms using the same test device.
   6. Apply the recommended placement or settings change, then repeat the tests and compare them with the original results before considering new equipment.
   7. If extra equipment is suggested, check its compatibility with your router and broadband setup, place it according to the plan, keep the old settings recorded, and test every smart-home device after installation.

   Prompt

   Help me improve Wi-Fi coverage for my smart home. Use only the information I provide and clearly label anything that is uncertain. Do not assume my router, house construction, broadband speed or device locations. First ask for any missing information that materially affects the recommendation, including the router and broadband equipment models, broadband speed, house layout and number of floors, problem rooms, device types, whether the devices use 2.4 GHz or 5 GHz, current Wi-Fi names and security settings, and speed or signal tests taken in the affected rooms. Then give me a step-by-step plan in this order: safe checks that change nothing, tests to identify whether the problem is signal strength, interference, broadband performance or a faulty device, router placement changes, settings changes, and only then equipment options. Explain where to place any access point or mesh unit and why. Do not recommend disabling security, using unsupported firmware, or buying equipment unless you state the compatibility checks first. For every proposed change, say what result would confirm it helped, how to undo it, and how to compare the result with the previous test. Keep the plan suitable for a UK home and do not invent prices, product specifications or broadband provider rules.
