I've been reading the forums looking for information on this issue.
Found other routers with similar problem and tried their fixes (when possible) to no avail.
I don't have the router registered on mydlink anymore as it was one of the reported causes of this issue. It's a brand new, clean set up using OpenDNS servers in the Setup>>Internet>>Manual Internet Setup
Configuration is saved and I have flushed the DNS resolver as well as cleaned the cache on the browser but yet, the OpenDNS updater still reports as not using OpenDNS and all sites are accessible.
Someone on the 825 forum mentioned parental controls but the 850 UI doesn;t have parental controls under Setup.
Can someone tell me if upgrading to the latest FW might solve this issue?
Thank you,
Flavia
