checklist when a machine can't get on the internet

I set up a new computer for a friend a couple states away.  He now can't get on the internet - just days after the install.  It's win 7

Looking for things you would check over the phone with him doing things.

I have so far -

port light on back of PC
port light on router (other machines in the house CAN get on the internet, so it's a local issue)
ipconfig - getting an IP address?
ipconfig - release / renew just to be sure
ping the router
ping 4.4.4.4

other things?

Those were things I was going to check, but I was looking for a list of things to type on a page.

Just spoke with him...  he can ipconfig / release  then ipconfig /renew.  He gets an IP address from the dhcp server which is the router.  So the physical connection to the router is working.  The NIC is working

He can ping himself.  But he can't ping the router.  He has a message next to the clock that he doesn't have internet access.  

A firewall issue, it sounds like, right?  That he can get a DHCP address but can't ping even on the lan, let alone get out on the web?

It's probably a firewall issue.  Have him temporarily disable it to see if he can get on the internet.  On the router is ICMP disabled?  That would explain why he can't ping it.  What happens when he pings 4.2.2.2?  This is one of Google's DNS servers and it will reply if he can reach it.  also have him tracert to 4.2.2.2 and see where it stops.

192.168.2.151

I can ping the router 192.168.2.1 from other machines.

yeah, gotta check the firewall.
