When troubleshooting a computer that suddenly fails to connect to the Internet, it is important to rule out the causes one at a time. Based on the “No Internet” symptom, check the router/modem or ISP problem and the network adapter/IP/DNS settings, then proceed to the next step. Compare with other devices and wired connections to narrow down where the problem occurs: PC, router, or ISP.
Among Internet problems, the “Wi-Fi connected but no Internet” symptom may be related to the router’s Internet line or DHCP/DNS problems. Check the wireless adapter status, saved profiles, router/signal quality, and driver in order.
