Downloaded the latest 1.0.0.29 firmware for my RV134W and upgraded it few days ago. Today was notified by Dyn.com that my DNS hostname was blocked due to excessive updates. Checked the Dyn.com website Host Update Logs and indeed the RV134W is sending updates every second! Downgraded back to 1.0.0.21 and no such problem anymore.
How can I report this bug found to Cisco?
P.S. The router is now sending updates or checks to Dyn.com every 10mins which I find it too frequently. Anyway to change the timing?
