A wireless device suddenly losing its internet connection while local Wi-Fi remains active is usually triggered by a temporary router crash, an internet service provider outage, or an expired IP address lease. Network routers handle massive amounts of data and can occasionally experience software freezes or memory leaks that block traffic passing from connected smart devices out to the wider internet. Additionally, if your internet modem lost connection due to a brief power glitch upstream, local Wi-Fi will stay up without providing actual web access. You can troubleshoot this common issue by performing a complete power cycle on both your modem and router, unplugging them for sixty seconds before plugging them back in to refresh local routing tables and clear stale cache data. You can verify that the connection has been successfully restored when network status lights stabilize and web-dependent devices reconnect.
