Even if you do everything right, your router can be vulnerable to hackers. Findings from a 2018 router firmware study found that 83% of the 186 home routers tested had firmware errors/vulnerabilities to hacking. The average number of vulnerabilities was 172.
So, while the network setup is a one-time activity, as the “router administrator,” you should plan on an occasional (at least annual) login to perform any needed maintenance; e.g. updating the router’s firmware from the router manufacturer’s website. If unsure how to do this, as it’s a very occasional and very important activity, consult a professional.
