I just purchased a brand new Imac and ITunes doesn't recognize CD names

Question

Hello,
I come to this forum humbly and with gratitude.  These Apple Support Communities have saved my sanity countless times as I was learning Garage Band several years ago. 
I recently purchased a new Imac (May '11) to use primarily for Logic recording.  I decided to import a few CDs from my collection (all major label artists/store bought CDs).  The first CD I placed into the CD drive was not recognized by Gracenote.  I thought this was perhaps I was trying to import a CD I purchased outside of the US.  However, when I looked up the artist I found their entire collection at the iTunes store.
Now, I'm almost 100% sure this is user error and I'm hoping you can help me.  Every CD I place into the CD drive of my iMac is not recognized.  I have read many 3-4 year old posts about this same issue, but I have not seen any recent ones.  I have read that security settings need to be adjusted and I have experimented with the firewall turned on and off to no avail.
Any insight/advice would be greatly appreciated.  If this topic has recently been covered, please excuse my ignorance, I was simply not able to find any current solutions.
Thank you,
Jeff

Hi Diane,
First off, I want to thank you for taking time to respond and help me, I really appreciate it!
I have verified everything in the iTunes Prefs > General, and there is a check next to automatically retrieve CD track names, and yes, my internet connection is active. 
Instead of going off of the wireless router, I simply connected my ethernet cable directly to the back of my iMac because I suspected there were some connectivity issues.  This move seems to have improved things greatly. 
Update:  I restarted my iMac and iTunes now seems to be automatically connecting to Gracenote to find the track names.  However, various CDs from non US-based artists are still not showing up.  What puzzles me is that I am always able to find their entire song catalog and artwork on iTunes if I search for it.  Do you have any idea why this might be?
Also, is there a wireless router that you would recommend for iMacs?
Thank you for your digital assitance!
Best,
Jeff
