Ok so here is my problem. I recently built my own computer and have had no problems at all. All of a sudden my internet stops working on just that computer. I have 3 computers in the house and the other two are working just fine. I have gone to command prompt and did that ipconfig /all and got: Windows IP Configuration Host Name . . . . . . . . . . . . : ryan-014d09bf2d Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Unknown IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : hsd1.wa.comcast.net.

I then tried pinging my default gateway and i timed out everytime. This is where I'm at a loss so can anyone help me?

Open CMD and try these two commands and see, the result. tracert 68.87.69.146 tracert cns.beaverton.or.bverton.comcast.net The first command makes a traceroute to the first listed DNS server in your configuration. If this is working, you can get out through the internet. The second command makes a traceroute to the first DNS server, but it must first resolve the name to get the ip address of that server. If that doesn't work, you got an DNS problem. In this case, post the result, on where the traceroute stopped.

for the first request it said it timed out every time. And for the second command it was unable to solve the name. I talked to comcast last night and they said that most likely my network adapter has stopped working correctly.

Couldn't say that at this stage, because the only thing we know right know is, that you can't get out and can't resolve hostnames. Can you ping your router (192.168.1.1)? If not, have you tried to use another cable? Also have a look at your router. When a computer is connected to it, there should be a LED flashing for the port, the computer is connected to.

yeah i've already tried pinging my router and it times out. Tried two other cables and both don't work and all the right led lights are on. I've also tried resetting my modems and router

Ok, what does the network environment show up. Is there listed a LAN-connection or is it shown as e.g. LAN-connection (2) or something like that? Is there more than one network card installed in your pc?

it says Local Area Connection 2 and there is only one network adaptor and it's integrated into the motherboard
