Windows 7 - Unidentified Network No Internet Access

I have a new Packard Bell PC with Windows 7 preinstalled.  I have had the tower replaced once, as it was suspected that the issue was caused by a fault with the wireless card.

I initially connected to the internet - albeit slowly and briefly.  It shows that it is connected with my network but whatever I try I have Unidentified Network and No Internet Access showing

I can connect through a 3mobile dongle.  Just not via the wireless card.

I have looked at so many suggested fixes, and have tried as many as I am able, but I am so lost as to what to try next.

Any suggestions?

Many thanks

Hello again

We have some problems with this happening at work. We found out that the issue has something to do with IP version 6.

We found out that disableling the IPv6 protocol helped.

I welcome you to try it.

First off you need to start a command prompt with admin rights. This can be done by pressing the start button, choosing "All Programs" --> Accessories --> and rightclicking Commandprompt, choose "Run as administrator".

Im sitting on a Danish language box, and the translations are made from memory.

Once you got your command prompt type the following:

netsh <press enter>

interface ipv6 <enter>

isatap set state state=disabled <enter>

The prompt will respond with an "OK" if it was succesfull.

to exit type:

quit <enter>

If you need to reverse the change and return to standard settings, do the above but replace the word in the isatap command "disabled" with "enabled". Very very few networks run Ip version 6, so the change has pretty low impact, but the bug is really annoying.

Let me hear if it helps.

Try disabling the McAfee network agent service. Run > "msconfig" > Services. I disabled the mcafee network agent and the mcafee firewall core service. 

This solution fixed it for me!

3 month old Dell laptop, preinstalled with McAfee trial suddenly had this "Unidentified Network no internet access". Thanks to this forum for the solution.

    Hello all

    turning firewall/router appliance off and on did it for me - this is the story:

    Did a small rearranging of my network this afternoon and got the much cursed error :)

    All i changed was cleaning up me network cables and removed a switch. The network cables that was plugged in the switch, i moved to my firewall box. Then i got the error when i turned on my win 7 computer that had its cable moved.

    My mac had its cable moved too, but that worked as allways. I went through the internet, firewall, security essentials, driver reconfig, all short of removing the adapter in the registry or resetting the TCP/IP config.

    The thing that worked was cutting power to my firewall and turning it on again.

    Geek alert: What i believe is that you get unintentional ARP poisioning of the gateway and the ARP table needs to be flushed in all the core network boxes, that you use with the device that has the problem - WiFi access point, switches, routers, firewall - because they all contain the old MAC address of your computer.

    Its my only hunch so far. The ARP table in the network boxes are usually refreshed after a while, but maybe they somehow keep the entries.

    Need to put a wireshark sniffer on the network to flush it out.

    Have fun with it
