DNS unable to resolve ip address....

[opnight]

i did that cmd...

my ip address and Default Gateway are the same. i cannot see a TCP address tho. my pc is correctly connected to the router and the cables are in properly oh there is no light on the back of my router but the USB light on the front is light up and there are no other machines hooked up to the router....u said about pinging the router how do i do this ??

Your PC's IP address and Router's/Gateway's IP address should not be the same, if it is there is something wrong right there.

So, it sounds like you connected the router/modem unit to your PC via USB which I don't know much about. I mainly deal with RJ-45 (CAT-5/5e/6) type wired Ethernet connections, however the ping test still applies:

Also see the attached screenshot to check on the TCP/IP Protocol properties window to make sure your settings are the same. If the modem is also acting as a router that means the router is your DHCP and DNS IP address is going to be whatever the IP address(es) of your ISP's DNS server(s) is/are. Generally there should be 2 DNS server IPs listed but only one used and the other is used if the first one doesn't respond to calls made by your PCs.
When DHCP is used then you MUST not manually configure the IP address for your machine, it should be set to 'automatic' as seen in the screenshot #1.

TCP/IP Protocol IP is same for everyone, it is always 127.0.0.1
pinging that IP pretty much tells you the TCP/IP protocol is functioning at a software level (it doesn't actually use your NIC or your connection).

Pinging your gateway is the key step which is tests the actual connection between your system (NIC) and Gateway (Router's internal port where the cable coming from your machine connects to).
This is how you ping an IP address:

Start > Run > cmd > OK
Then type the following: ping_xxx.xxx.xxx.xxx

Note: Replace x with the gateway address you obtain by running ipconfig command as explained previously, ok?

See the attached screenshot #2 for an example of obtaining and pinging the gateway.

yes my router is connected via USB, DHCP is enabled. i pinged TCP/IP Protocol IP and i sent 4 and recieved 4, but the ip ping didnt work, but all the others work.

That IP config was run for Local Area Connection #3, was that the right one?

Besides the 'Media State' showinf Media Disconnected, the only odd thing I could notice was the DNS IP addresses.
Though as I mentioned before I am not too familiar with USB based LAN connections, the IP addresses listed for the DNS servers didn't look right.
Are the settings for the Advanced TCP/IP Settings window same as the ones on the screenshot #1? ON the Advanced TCP/IP Settings section click on the DNS tab and check that page too.

You should not have any IP address entered manually for your machine, gateway or even the DNS servers. IF everything was really set to automatic then you could try running:
Start > Run > cmd > OK and ipconfig /flushdns (ENTER) first then ipconfig /renew (ENTER) afterwards.

Other than these, I would have to let someone who had experience with USB highspeed connections speak up.

i did the ipconfig /renew thing and it didnt work
*see attached image*
i changed to get the DNS addresses automatic, i only added them in because some one in an earlier post said that might help..

Ok, so the DNS condifuration is set to automatic, then you do the ipconfig /flushdns
and
ipconfig /renew

You command didn't work cause you didn't type it correctly.
