Need help with infamous DNS error

I swear, I've had this exact same problem even when I first owned a PS2. A Comcast guy came to my house and installed a new cable/phone box from my standard cable box, and now I can't get my PS3 to connect online! I can usually fix the problem, but this one wants to follow me to my grave it seems. Can I get some help guys? I've been to forums all around the net, heck, I've even called Sony. I must be doing something wrong.

Here is the information you can work off of.

-I have a Comcast Cable/Phone box.

-The error is a DNS error with a code 80710102.

-I've tried both Easy and Manual settings.

-I have a D-Link DGS-2205 Router

-Even when I connect directly to the Comcast modem, it still doesn't work.

-I've tried entering the information from the command window command prompt Ipconfig /all.

-I've triend using static IP addresses and DNS codes.

-I've tried turning the Media Server Connection on my PS3 off.

-I've tried turning off my firewall.

P.S. Thanks for the help to whomever solves this problem. If you can solve this, then you're a god!

Try resetting the router; don't use any static information after and see if it connects automatically. sinistergoggles

Does resetting the router entail just turning it off or doing something else? I couldn't ever find a straight answer.

i had the same problem and like the guy said above i pulled the power on both my modem and router for 2 minutes. Then i turned everything back on and presto. Worked like a charm.

Most router has a small reset button you need to hold down for about.. 30 seconds. (probably need something thin to poke it with)  This will remove all your settings from the router and return it to it's default settings (like it was when you first bought it).  So you'll lose everything; including any wireless secrutiy settings you may have.  So.. yeah, only do it if you know how to set everything back up!
