Connected with ethernet but can't surf

Question

I have an 2010 2.8 GHz Intel core i7 iMac 27" OS 10.7.5 connected to AT&T Uverse broadband. Connection to the internet was fine until doing a Software security update today. After it rebooted I could not get on the internet even though it shows in the Network preferences that it's Connected to ethernet and has the IP address 192.168.1.66. I have tried 3 different up to date browsers and I use Apple Mail, but it will not get email. I try doing a software update and it can't "because of a network problem". I try Network Diagnostics and it says "Your Internet connection appears to be working correctly."
I can connect via wireless with the same connection on my MacBook Pro and iPad, but not with my iMac.
I have tried switching modem ports and ethernet cables. I was also able to connect vie ethernet on my MacBook Pro with no problem.
What could it be???
Bad Ethernet port??
Can I trash the browser prefs maybe?
Any settings in the modem? DNS or other settings?
Please help!

Answer 1

OK I did what you said Linc Davis. So here is the output collected from all the textedit windows in the order they appeared separated by dashed lines.
