Why is my WiFi filtered, but my wired computer is not filtered?

[ducknowles]

I'm new to OpenDNS. My WiFi is filtered, but my ethernet-connected computers are not. Why?

This is my setup:

Comcast Xfinity router, which I have had Comcast set to Bridge Mode (effectively now just a modem)

Connected to that is my Linksys EA4500 router.

I have entered the OpenDNS numbers into the static DNS fields in the Linksys router's setup.

The computers and the WiFi devices are both going through that router.

My testing of the OpenDNS test page shows that the WiFi is filtered, but when I test that page on the wired computers they are not filtered with OpenDNS--none of the three test pages.

Any help or suggestions?

Thanks in advance.

Hello ducknowles!

Depending on the model of some Linksys routers, you may need to fill in all fields of the DNS servers if you have more than 2 fields for entry. You can use any of the following DNS server addresses:

208.67.222.222
208.67.220.220
208.67.222.220
208.67.220.222

Can you give this a go and see if this fixes things for you?

On my router there are 3 static DNS fields under the section Connectivity-->Local Network-->DHCP Server. In those 3 fields I have entered the first, second, and fourth numbers you have listed above, and I am getting the problem I described. Below those 3 Static DNS fields there is a field called "WINS," which I have left at zero's, but it looks like it calls for the same type of 4 DNS numbers as the static DNS fields above it. (I attached a screenshot.) Should I fill in "WINS" with that 3rd DNS number you gave above?

If possible delete the zeroes from the WINS field, else the router may look after a WINS server at 0.0.0.0.  Don't fill this with any DNS resolver addresses, under no circumstances.

Also, please copy & paste the complete plain text output of the following diagnostic commands here:

   nslookup -type=txt which.opendns.com.

   nslookup -type=txt debug.opendns.com. 208.67.222.220

   netsh interface ip show dns

When I delete the zeros and apply changes the router fills in the fields with zeros again.

I am using a Mac, so I entered the commands in Terminal:

duane-knowless-imac:~ duane$ nslookup -type=txt which.opendns.com.

Server: 8.8.8.8

Address: 8.8.8.8#53

Non-authoritative answer:

which.opendns.com text = "I am not an OpenDNS resolver."

 Thank you for helping me figure this out.

Yes, that's clear now.  You do not use OpenDNS as long as you have Google DNS configured on your Mac OSX computer.  Change your computer's network settings to obtain them automatically via DHCP from the router, at least the DNS settings.  Alternatively, replace the Google resolvers by OpenDNS resolvers.

As I thought, this has far nothing to do with WiFi or wired.

In my Mac's network settings it was already set for "configure IPv4" "Using DHCP." The alternative was "Using DHCP with manual address." I left it alone, but I did change the DNS settings. And it's working now! Thank you! I just don't understand why the router didn't override the Mac.

"why the router didn't override the Mac"

No router ever overrides computer settings.  Computer settings always have priority.  And it has nothing to do with "Mac", but applies to any end user device.
