Bad Internet Due to Hardware Glitches

Confirm this issue by observing the router's responsiveness to navigation and the consistency of the 'No Internet' error across multiple devices. A hardware glitch is confirmed if the local network is active but the WAN (Wide Area Network) connection is unresponsive, or if the router is failing to assign IP addresses (e.g., a device shows a 169.254.x.x address in ipconfig). This indicates the router's internal state machine has stalled and requires a full power cycle to clear temporary memory congestion.
