burton, don't fall into error by making assumptions about very clear defined things. Look here, the first response in a search page (altavista, google or other search engine):
http://support.microsoft.com/kb/160177. It is no problem with the node type in our problem. (I apologize for my correction. More, I forgot about those settings and I had to search on internet to find a proper answer).
krashsun, and after your connection works? What is the windows ip configuration?
Maybe it is not necessary to restart the computer, maybe the command:
ipconfig /renew
will sufice when you have that problem.
I ask you about the ip settings after you are able to connect on internet to see what ip address your computer reports, if it is a private ip address (so your modem-router acts as a router also) or a public ip address (so your modem-router acts as a bridge).
