Hi,

HELP!

I´ve been having a strange problem I cannot seem to solve.

My computer all of a sudden last week stopped displaying any webpages/connecting to the internet. It says it is connected (signal strenght/connection= excellent) but it won´t actually connect. Not to IE (7), but not to anything else either. The problem is both for the wireless as well as through the cabel connection.

I´m sure the problem must be the computer and not the internet though, because on my friend´s computer it works fine. I have tried to put all the settings the same as on his (gateway, dns, network mask).

I have already tried to reboot the computer.

I have tried to renew/reset the IP-address numerous times, but am not sure this is working right. I have manually tried to set it (same as the computer that does connect, except for the last two digits).
But when I do it through Run it will let me release the IP-address, however when i try to renew it tells me

¨An error occurred while renewing interface Local Area Connection: An operation was attempted on something that is not a socket.¨

I have also tried to reset WinSock.

It will not ping either, I tried yahoo.com and 66.218.71.198 - it tells me Destination host is unreachable.


The last windows diagnostics I have are as followed;

Please let me know if anyone has any suggestions.

Thanks a lot.

I want to try and narrow down the issue. I know you said you cant ping websites. I want you to try to ping a loopback and ping your router.

127.0.0.1 is your loopback address (to your NIC)

give that a try and let me know what you see. Also, check your network connections to see if you are receiving packets. I would also like to know the ratio of packets sent/packets received.

thanks for your cooperation~

First off, connect with a wired connection directly to the router or modem.


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

Start, Run, CMD to open a command prompt:

In the command prompt window that opens, type type the following commands, each followed by the Enter key:

Note: Type only the text in bold for the following commands.

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

Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog

Reboot the machine.




Next, do the following 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.

Since i couldn't copy the text straight into word/notebook i took two screenshots of the results.

Thank you a lot in advance, my replies might be a little slow because i have to run from home to internetcafe

regards

Try booting in Safe Mode with Networking and see if that changes. It appears you have a firewall blocking you.

 

[Maruanaya]

Yes! Writing you from my laptop now!

What would be my next step to try to make the "normal" mode working?

 

[johnwill]

Well, I'd start by disabling ALL firewalls and Internet security applications. If that does the trick, you need to enable them and check the configuration for why they're blocking your access.
