This problem is local to a specific laptop. Similar setup works fine on many other laptops.

I have a wireless network at my workplace I can't get my laptop to talk to it. The connection to the network happens successfully, but after it happens, no traffic can go in or out. I do not know the server configuration and I'm unable to get support from that end.

On the laptop:

  • Windows 7 Home Premium
  • No firewall is installed
  • Windows firewall is stopped
  • Ipv6 is disabled
  • Homegroup is disabled

Once I connected to the network I get the following ipconfig /all readings:

And this is the result of pinging default gateway:

Pinging 172.26.76.1 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.

Ping statistics for 172.26.76.1:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

The wireless connection level is strong.

Could you please help me troubleshoot this issue?

Update 1

Output of arp -a right after pinging the default gateway:

Did you obfuscate the DHCP and DNS servers in the wireless ipconfig? If not, then the 1.1.1.1 suggests a catch-and-release wireless connection like you would find at a hotel. This would require going to a website and getting redirected to a login page. If you ping google.com does it resolve? – Paul Sep 27 '11 at 1:29
@Paul: I did obfuscate DNS servers but not the DHCP server it really reads 1.1.1.1. Nothing pings and nothing resolves. I can't ping the dns servers, can't ping google.com neither by ip nor by name. Can ping myself, but that's about it. – zespri Sep 27 '11 at 1:53
Ok, can you trying pinging the default gateway, then immediately do an arp -a and see if you get a MAC address (as opposed to incomplete) for the gateway IP. – Paul Sep 27 '11 at 1:56
@Paul output of arp -a does not have the gateway IP in it. I'll post the output shortly. It has an IP that starts like the gateway IP but has different ending. – zespri Sep 27 '11 at 2:27

The different ending one is the broadcast address for the network, and is correct. That there is no entry for the .1 suggests that Windows did not even attempt an arp request (to determine the MAC of the gateway). I can't think of any reason why it would not do this, so perhaps it just isn't reporting the results. If I was at the machine I would be digging out wireshark and seeing exactly what was going on on the interface. – Paul Sep 27 '11 at 3:19
