    I can't access the internet on my laptop.

    I recently got a new laptop and am trying to share the current internet connection I have on my desktop with it.

    I'm using XP on the desktop and a 802.11 USB Wireless LAN Card.

    The laptop has Win 7 and a built in 802.11 g/b/n

    Now the laptop connects to the network fine, however when I hover the mouse over the connection it says "No internet access" and I can't connect to any sites on the net. When I use the IE troubleshoot it says "The DNS server is not responding"

    When I first tried to connect to the network and use the net on the laptop it all
    worked fine, however it suddenly stoppd working and brought up the "No internet access" thing. It did this until the next day (despite my attempts to fix it following various guides other people have put out there on seemingly the very same porblem) when it suddenly started working fine again. I had internet access, which I used for several hours. I resest the laptop a few times to make sure that it would keep working (which it did) however now it's doing it again and im pulling my hair out.

    I really hope someone can help.

    Edit:

    Also when I right click the connection and go to properties and it brings up all the details about the connection (eg. duration, speed, signal quality) it says the following -
    IPv4 Connectivity: No internet access
    IPv6 Connectivity: No network access

    Try these simple tests.

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

    NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

    Do NOT include the <> either, they're just to identify the values for substitution.


    IPCONFIG /ALL

    PING <computer_IP_address>

    PING <default_gateway_address>

    PING <dns_servers>

    PING 74.125.45.100

    PING yahoo.com


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

    <computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above. (For Vista/Win7, the IPv4 Address)

    <default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

    <dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.


    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    I need to see the ping tests I mentioned after the IPCONFIG /ALL, they're the reason for doing all this. :)

    I would guess that you have a non-Windows firewall or security suite on the desktop that is not configured to allow/trust the 192.168.123.x subnet or not configured to allow ICS.

    The only firewall i've got on the desktop is the windows one, the other security programs that I have are Malwarebytes, SuperAnti-spyware and threatfire.

    But if it was one of them then why would it sometimes let the laptop use the internet and others not?

    Also I don't know if this means anything or not but when I did the Ping 74.125.45.100 test the little icon and the "no internet access" thing disappeared from the laptop for a few mins (it then came back) however this time when it went away (as apposed to other times) I still couldn't access anything on the net. It acted as though I still had no internet access.

    OK, I was going by just that one set of results. If you can sometimes ping the desktop (192.168.123.1) and sometimes not then probably the wireless connection between the two is repeatedly connecting and disconnecting or else there is significant wireless interference that is intermittently interrupting communication.

    Please post a screen shot of the Networks page of the Xirrus Wi-Fi Inspector. If the two computers are pretty close the output can be from either; but it would be better to get the output from both.

    Screenshot of the laptop with Xirrus Wi-Fi Inspector attached below.

    The wireless signal is "excellent" on both the desktop and the laptop and the laptop always connects to it and I so far havn't been disconnected once. It's just that it says "no internet access" most of the time.

    There could possibly be interference from something that doesn't show in Xirrus (e.g., 2.4 GHz cordless phone), so you could try channel 11.
