The Wi-Fi symbol only proves a device sees the shop’s wireless network. It does not prove the Wi-Fi box reaches the internet or that the register can reach its service.

• Every device fails at once versus only one device.
• A wired computer works while Wi-Fi fails.
• Failures cluster in one room or at one busy time.
• The register shows a message from the company that runs it or says a security setting blocked it.

• Record the time, devices, location, and exact error.
• Check the internet provider and critical service status.
• Test one wired device and one nearby wireless device.
• Reboot only the identified layer, then document what changed.

NYC businesses can call us for remote diagnosis or an approved on-site visit. Outside NYC, we can help with the website and documentation, not promise a local dispatch.
