Yes they do – in fact, the security settings on a home modem/routers matter whether or not you are working from home.
Most home modem/routers are provided free of charge by your internet provider. This means they are usually very basic. Furthermore, the administrative credentials for accessing them are typically not very secure – Admin/Admin is quite typical of a username and password. (NB these are not to be confused with the password that your provider provides for WIFI access). There is a huge amount of information available online about router/modem models and how to ‘hack’ them.
For this reason, you should ensure your router/modem administrative credentials are made secure. If you are working from home regularly it is worth considering upgrading to a professional-grade router for additional security.
