A router that needs daily reboots may have firmware, heat, power-supply or upstream service problems. Check firmware, ventilation and modem status, and record outage times so you can distinguish a router fault from an ISP.
A fast internet plan does not guarantee a stable TV connection. Test the TV near the router or with Ethernet if available, restart the app and TV and compare another streaming service to separate Wi-Fi, app and provider.
Strong Wi-Fi signal only proves the laptop can hear the router. Compare a second device on the same network, restart the laptop, forget and reconnect to Wi-Fi and check updates before changing the router for everyone.
Use a normal reboot—unplug power briefly or use the router’s restart option—rather than the recessed factory-reset button. A factory reset erases customized Wi-Fi names, passwords and other settings.
When only one device drops, focus on that device first: forget and rejoin the network, update its OS and Wi-Fi driver, disable aggressive battery saving and compare performance on another network.
If speed tests look good, buffering can still come from weak Wi-Fi at the TV, congestion, an overloaded streaming app, DNS/router issues or the service itself. Test the TV on Ethernet or a different network before replacing.
