A Wi-Fi connection only confirms that your device can reach the router. Internet access also requires a working modem or fibre terminal, WAN link and valid ISP connection.
Check the Scope
Test several devices. One affected device suggests a local setting; every device failing points to the router, modem or provider.
Read Status Lights
Check power, internet and WAN indicators against the device guide. A red or amber internet light often signals loss of upstream service.
Restart in Order
Power off modem and router. Start the modem first, wait until online, then start the router.
Inspect the WAN Link
Confirm the modem cable reaches the router WAN port and check whether the router receives an internet IP address.
Test DNS Carefully
If IP-based connections work but websites do not, try a reputable DNS resolver or return custom DNS to automatic.
Frequently asked questions
Why does Wi-Fi show full signal?
Signal strength measures the local radio link, not the upstream internet service.
Can an unpaid bill cause this?
Yes. Provider suspension or account activation issues can leave local Wi-Fi available.
Should I factory reset?
Only after simpler checks and after recording ISP settings.
