Troubleshooting internet connection errors and router restarts

Internet connection issues, such as the C1 error code on Bouygues Telecom Bbox devices, typically indicate that the hardware is powered on but unable to access the network. Common causes for this specific error include loose cabling, issues with the fiber SFP module, or a failure to retrieve an IP address.

Restarting an internet router can resolve many connectivity problems because these devices function as small computers with processors and memory. Over time, a router may experience saturated memory, cluttered connection tables, or degraded synchronization with the service provider. A restart clears these processes, resets the connection negotiation, and allows for pending software updates to install.
