No Ip address? Signal but no internet!

First off I apologize, I know this has been covered a thousand times (any google search will reveal.) Problem is the myriad answers combined with a wife who is intolerant of my do it yourself-ness.

knowledge level is one step above rock.

In an effort to pay Comcast as little as possible (a bucket list thing for me) I replaced their Motorola surfboard/router all-in-one with a

Motorola surfboard SB6141 from Costco (FYI, $75 right now.)
Linksys WRT54G ver2. wireless router

Windows 7 shows full green bars but has that damned! annoying little yellow exclamation mark and says no internet connection

However, when I open a browser I get a Comcast "activate your equipment" page for the new modem (so there is obviously some connection right?)

I activate the modem and get the internet on my laptop when it is Ethernet plugged into the modem, but the wireless does not function. When I do the Win7 diagnostic I get a "DNS server unavailable" message.

The properties on my wireless show "Obtain IP address automatically" and "Obtain DNS server address automatically" checked and I have reset my router, modem, and computers.

I don't know if it matters but my router has been sitting in storage since 2010
 
Solution
call Comcast and register your modem's MAC address with them otherwise you will not get any internet.

also you should return their modem/router otherwise they most likely will charge you a monthly fee.

once registered and the internet connection checked while on the phone with them, you should be able to connect your router to the modem and have internet access

Thanks. I'm pretty certain the router is the problem. I activated the modem and it worked fine (got Internet when hard lined in to the modem)

In getting full signal just no connectivity on my PC and lap top when on wireless.

Someone mentioned pinging, does that sound like a solution?
