I can't get OpenDNS working on my computer.

Since I have a Comcast cablemodem (which also is used for my phone) I can't change any settings there, they are all hardwired. But when I try to change the setting on my computer to override Comcast's DNS, it lets me do that, and even my Network Connection says it's using them.. But after cycling my modem, clearing my browser cache and rebooting, I still get the message saying that I'm not using OpenDNS.

Here are my Network Settings on my computer: http://i.imgur.com/D7574wK.png

It says I'm using OpenDNS DNS servers, but all I can think of is Comcast is blocking it through it's router or something.

It appears that you're IPv4 settings are correct, but that Comcast is also giving you IPv6 settings. Since OpenDNS doesn't yet support filtering IPv6 traffic it appears that your DNS traffic is going out via IPv6.

As a test try disabling IPv6 on the computer and testing again.

If it works then you have two basic choices 1) disable IPv6 on all devices on your network, not really preferable, desirable, and perhaps not even possible for you 2) get your own WiFi routers (depending on model they are easily available for $50 - $125) and disable IPv6 on the router itself. Not only can you control your internet traffic better this way, but your settings are not dependent on Comcast for your network configuration and can change ISP's basically at will, or if necessary having the cable model disrupted without losing any settings or configurations.

Turning off IPv6 seemed to work! I'm not aware of anything I'm using requiring IPv6, so hopefully that will be all that's needed.

Just because you aren't aware of anything using IPv6 doesn't mean it's not in use. IPv6 is the default protocol in Windows since Windows Vista, and by default traffic will use IPv6 is there a path to the endpoint. In Windows 7 features were introduced that only work over IPv6. In an environment where there are more than 1 Windows 7 or later computers having IPv6 is available makes noticeable speed and reliability improvements in local networking, and it is strongly recommended by Microsoft and tech professionals not to disable IPv6 other than for troubleshooting or unless there is no other options.

That's just one of the reason I always recommend that people get their own router, so that they can control their own network, and in this particular case, so that you cannot have internet traffic and protocols forced upon you by your ISP that you don't won't.
