Only 1 LAN PC blocks websites, others don't
Hi,
My network map looks like: Verizon Fios modem -> Router -> PC1 (LAN port) / PC2 (wireless) / PC3 (wireless) / Mobiles (wireless).
I use OpenDNS on the Fios modem so it basically every device under it should use same OpenDNS if they are all set to automatically look up for DNS. Is it correct?
If yes, why does the websites block only work on PC1 (LAN) but doesn't work on the rest of devices?
PS: I tested all devices using http://welcome.opendns.com and all of them has check marks.
Thanks,
Ken

Not necessarily. Especially not as you use two devices, a modem and a router. And I have heard about strange things regarding router firmware...
"why does the websites block only work on PC1 (LAN) but doesn't work on the rest of devices?"
For example, because the one PC is connected wired, whereas the rest is connected wireless? Or because they have different network configurations, for example IPv6 enabled or not? Or they have individual additional DNS server addresses configured? Or you run an antivirus program on one PC and not on another intercepting your DNS traffic? Or even more reasons? There are so many!
Copy & paste the complete plain text outputs of the following diagnostic commands to here, from a PC where it does not work:
nslookup -type=txt debug.opendns.com.
nslookup whoami.akamai.net.
nslookup www.exampleadultsite.com.
netsh interface ipv4 show config
