If you’re having trouble with the RV220W detecting Ethernet cables when connecting to other devices, make sure you’re running the most recent software. You can download the latest firmware here: http://www.cisco.com/cisco/software/release.html?mdfid=283118607&softwareid=282487380&release=1.0.1.0&relind=AVAILABLE&rellifecycle=&reltype=latest&i=rm. If the router still isn’t detecting cables, the issue may be related to your port settings. You can find more information on configuring port settings in the administration guide: http://www.cisco.com/en/US/docs/routers/csbr/rv220w/administration/guide/rv220w_admin_v1.0.1.0.pdf.
