The author discovered two hidden networks on their TP-Link router, which were not configured by them and did not appear in the router's admin interface. These networks are a result of TP-Link's OneMesh feature, which is enabled by default and cannot be disabled on all models. The author considers this a security risk and a waste of energy. TP-Link has been slowly rolling out firmware updates to fix this issue, but the author's router model has not received an update yet.
