If you experience a problem after upgrading the RV220W to firmware version 18.104.22.168, you can downgrade to the previous version 22.214.171.124. You’ll find a workaround for reverting to the previous version in this release note: http://www.cisco.com/en/US/docs/routers/csbr/rv220w/release/notes/RV220W_Release_Notes_126.96.36.199.pdf. And you can download the firmware, version 188.8.131.52, here: http://www.cisco.com/cisco/software/release.html?mdfid=283118607&softwareid=282487380&release=184.108.40.206&rellifecycle=&relind=AVAILABLE&reltype=all.
