Should I restart a router?¶
Only when a defined safety, containment or service need outweighs the loss of volatile network evidence and operational continuity.
Restart is not neutral troubleshooting¶
It can clear logs, sessions, leases, tables, configuration and alerts and interrupt internet, telephony, cameras, alarms and payment systems.
Record device, lights, cables, warnings, uptime and interface first. Define whether the objective is evidence, recovery, convenience or containment.
Preserve before-and-after state¶
Seek network or incident advice. If restart is unavoidable, record authority, exact time, expected impact and any warning.
Afterwards capture changed addresses, connections, alerts, uptime and service failures. Do not present the rebuilt state as evidence of what existed earlier.
Key takeaway
Restart a router only through a recorded operational decision that accepts the loss of volatile state and service impact.
