    Hey guys. I have a laptop that says that says that it is connected to the network, but it doesn't allow me to connect to the Internet. I have tried this laptop on numerous networks and nothing happens. And I think there is a problem with the laptop because my other laptop is picking up the signal perfectly. The laptop that is causing problems is a Toshiba Satellite U205-S5002. Any help would be greatly appreciated and if you guys have some followup questions, I would be happy to answer them.

    Please try to connect, preferably both ethernet and wireless, and show ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    Looks like good ethernet and wireless connections.

    Open a command prompt and try these pings; you can show the results the same way you posted the ipconfig /all.

    ping <adapter IP> [above the adapter IPs were 192.168.1.101 and 192.168.1.102]
    ping 192.168.1.1
    ping 206.190.60.37
    ping yahoo.com

    You have internet access (206.190.60.37 is yahoo.com) but DNS is not working.

    Make sure the following services are running (Control Panel - Administrative Tools - Services).

    DNS Client
    Network Location Awareness

    If they are running proceed to ...

    Sometimes, for unknown reasons, we run into a situation where the normal practice of using the router's IP for DNS does not work. Try assigning OpenDNS servers to your computer's connections.

    Okay, the DNS Client & Network Location Awareness were on started, so I think that is what you wanted.

    I added the OpenDNS servers to the laptop and the Internet is still not working.

    But, I do have a few questions about the OpenDNS. Should I install the OpenDNS-updater on the laptop? And does it give you a DNS server address specialized for your computer or is it the same for everybody?

    -Type: NETSH int ip reset reset.log
    -Type: netsh winsock reset catalog
    -Type: ipconfig /flushdns
    -Type: ipconfig /registerdns
    -Reboot your computer.

    You have Windows XP, right? Just do step 1, assigning DNS servers. I haven't even looked at the other steps beyond that.

    You still can't ping yahoo.com? Strange, darn it.

    I don't think the following repairs will help in this situation, but they won't hurt either ...

    (From a JohnWill post)

    TCP/IP stack repair options for use with Windows XP with SP2 or SP3.

    Start, Run, CMD, OK to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

    Reboot the machine.

    Pollex: I tried what you said and it is still the same

    TerryNet: Yes, Windows XP SP2. What you told me to do was basically the same as Pollex and still no Internet and same result when pinging Yahoo.

    I'll think about this overnight, but I can't think of any more "tricks." How about showing another ipconfig /all since there has been a change since the last one, please.

    Sure, no problem. I'll check back tomorrow.

    Here is the ipconfig/all. I went ahead and redid the OpenDNS server thing because I noticed that it got cleared.

    When you have both connections Windows will use the wired one; so it may still have been using 192.168.1.1 as DNS. WAIT! I was blind before. The DNS is set to 192.168.0.1. I don't know how that could have happened, but that's obviously a problem--it should be the IP of the router (192.168.1.1).

    On the ethernet connection set the DNS to 'obtain DNS auto' if that bogus DNS is now set, or else use the OpenDNS servers.

    I didn't understand your first paragraph, so I didn't do anything there.

    For the second paragraph, on the ethernet connection, the dns was set to obtain automatically. I changed it to the OpenDNS servers and still nothing works.

    Here is an updated ipconfig/all...

    I agree with your statement in your first post, "And I think there is a problem with the laptop."

    It should not have been getting that DNS from the router (what does the other computer get for DNS?) and it should be working now with all the stuff we've done.

    At this point I can think of nothing except for a Repair install of Windows; and a fresh install if that doesn't work.
