Have an RV082 v1.1 FW 1.3.98-tm that has been rock solid for a couple of years and is now, suddenly, experiencing dead crawl DNS resolution.
No changes in configuration prior to the behavior starting. Tried rebooting the unit, no changein behavior.
There's an internal DNS server that resolves internal resources, but everything else gets pushed to the RV082.
I've tried Comcast, Verizon and Google DNS servers at the router level, and the results are the same -- so that rules out the DNS servers themselves.
Change the DNS servers at the NIC level on a wrokstation, and resolution occurs quickly and reliably.
I'm looking to reset to Factory Default and reload the configuration and likely upgrade to FW 126.96.36.199-tm or 2.0.2.01-tm but I do see similar issues reported with those firmwares, and moreover, in a mixed Mac/PC environment.
Was wondering if anyone else has experienced these issues, could identify a root cause and resolution.
