Of course it's sending, but if it's not receiving, then it could be a couple of things. I'm guessing that it's an IP conflict or cabling issue but it could be some sort of firewall blocking the traffic.

To start, check if the machine that is actually getting online is using a DHCP address or not. The "easiest" way to do this, is to click, start>run; type cmd then at the command prompt type; ipconfig /all. Look for the line that says
"DHCP enabled.................{yes/no}"
Also, look for and post the lines from each machine starting with:
"IP Address" to "Default Gateway".

Find out and post back with the information mentioned above.

Ok, now I see that you have only listed the IP information for one of the machines. I believe that the Windows Network Wizard hasn't helped any. For starters, on BOTH machines, in the Network Connections section of Control Panel, make sure that there isn't a bridge. If there is, delete it (only important if using more than one connection on the computer, and it's still useless). Now we will reconfigure your network to make sure that everything has what it's supposed to have.

The following settings are a common standard in the networking industry and are recommended.

Router
WAN Interface: Obtain IP Address Automatically
LAN Interface:
IP - 192.168.1.1
Sub. Mask - 255.255.255.0

Computer 1
IP - 192.168.1.100
Sub. Mask - 255.255.255.0
Def Gateway - 192.168.1.1
DNS - 192.168.1.1

Computer 2
IP - 192.168.1.101
Sub. Mask - 255.255.255.0
Def Gateway - 192.168.1.1
DNS - 192.168.1.1

Set everything up this way, and see what you have for a connection. I will be posting some links to a couple small tutorials in my signature soon that deal with the manual configuration if you need help with that.

Ok babytazz, I added a link in my signature to a short, but hopefully helpful tutorial on how to static your own addresses. Since we are going to be giving a static addresses already mentioned in another post, you won't have to worry about finding the scheme of the network. Also, when you start to assign addresses, you should start by giving the router the new address first, you will lose connection, then do the machine you are on, that will give you the connection back, and you will be able to continue using the new address (if it was changed).

Ok, do the two computers ping each other? If so, try pinging google.com from the computer that can't access the internet. Also, if you are up to it, download the following:

Ethereal
WinPcap

Then install on the machine that doesn't connect to the internet. Run the program and click the Capture, and Start Capture at the top of the page. Once the capture is running, try to ping the following in order:

1) 192.168.1.101 If that works go to 2
2) 192.168.1.1 If that works go to 3
3) 192.168.1.100 If that works go to 4
4) ping external IP interface on router If that works go to 5
5) ping google.com If that works, try internet, if not, go to 6
6) ping 216.239.39.99 If that works, PC2 is having a DNS issue. If not, we will continue the search for a solution.

I apologize, I got caught up so much in the instruction for the captures, I forgot to ask you to save the files in the libcap format and email them to me at greazy@gmail.com and I will take a look to see if I can spot what is stopping it.
