Unable to setup the Netgear Router with OpenDNS to filter unwanted content

Dear Team,

I am unable to configure the router with OpenDNS. I have tried to follow several threads on the forums, however, failed to succeed.

My router Make and Model: Netgear N300 WNR614

I have run few commands as it was mentioned by the support person in case if this adds value:

C:\>nslookup -type=txt debug.opendns.com
Server: www.routerlogin.com
Address: 192.168.1.1

DNS request timed out.
timeout was 2 seconds.

*** Request to www.routerlogin.com timed-out

C:\>nslookup www.exampleadultsite.com
Server: www.routerlogin.com
Address: 192.168.1.1

Non-authoritative answer:

Name: www.exampleadultsite.com
Address: 67.215.92.210

1. I have ensured that the DNS Settings are set to OpenDNS defined addresses.
2. I have no networks under the settings TAB of OpenDNS Dashboard

Please help me with the steps I should take in order to setup this in a way that the desired categories should be filtered out.

I am using this in a small home office and would like to ensure that the productive time is not used in a wrong manner.

Looking forward to hearing from you soon.

Best Regards,

Syed H
