Notes

A Wi-Fi 7 mesh system is the backbone for smart-home devices, work-from-home, streaming, and security cameras. Failures often present as frequent reboots, overheating, dropping client connections, or ethernet port issues.

Repair only makes sense for simple external components (power brick, cable, ventilation changes) because the radio modules and mainboard aren't economical to service. Replace is justified when performance becomes unstable or the platform stops receiving security updates-especially since routers sit on the internet edge and outdated firmware increases risk.

With mesh, you should also consider partial replacement: if one node fails but the rest are healthy, replacing a single node might be cost-effective if the ecosystem allows it. Otherwise, a full-system refresh can restore stability and coverage.
