Hi.
It's been a very frustrating few days as I have been searching everywhere for a solution to my problem, but to no avail.
I have been using Ethernet connection for about a month now and it has been working perfectly. However, yesterday, for no apparent reason I cannot connect to my router. If I try and connect to it, it just says "Unidentified network" and "No Internet Access". Wi-Fi connection works fine, even if it is a bit slow. All the other computers in my house connected through Ethernet are working perfectly fine. I have a feeling it is a problem with my Ethernet controller's IP and Default gateway. I am okay with computers but I honestly have no idea what all the networking jargon means, so please keep it to a minimum.

In Short - I can't connect to my router through Ethernet, as it just says "Unidentified network" and "No Internet Access". All the other computers in my house conncted by Ethernet are working fine.

So Hamichi no longer shows up as LAN2 in your ipconfig?

If not, my last idea is to run a registry fix that is under Option 2 HERE that I've used a couple of times with success. It's rare that I have to get that far though. Now that Hamichi is disabled some of the earlier ideas may work too.

These tough unidentified network issues are not uncommon and always make me wonder why MS didn't include the security policy editor with Home Premium, at least as a later fix.

Which version of Windows 7? This is the typical unidentified network problem, any chance that you can change the network type from public to work or home?

If you are not using the Home Premium version, open the start button and in the program search box type secpol.msc, click on network list manager policies folder, double click unidentified networks in the right pane, change the settings to: location to private and user can change location.

If you are using Home Premium, you can try changing the Ethernet adapter MAC address with THIS free app.

I was using Home Premium. I did what you suggested with TMAC, but it hasn't made any difference.
I was wondering if, when I update to 64 bit windows in a few days, it would fix the problem. Is it possible this would?

Usually re-installs have not solved this issue, but you might get lucky. The problem with Home Premium is that it lacks the security policy editor. There is a powershell script that should reset the network. Look HERE and HERE for the PowerShell information (it is in Win7 just type PowerShell in the start button run box) and the script that you need to run.

That seems to have solved the problem.
Many thanks for now, however this has happened before and it may not last. Once I am sure that this is fixed I will come back to this thread and select your answer as the solution.
Thanks again,
Jacob

It has stopped working again. I've saved the script but I actually don't think that is the thing that solved it, it may just have been fortunate timing.
By any chance would you know what the output of PowerShell should be after I have entered the script?
At the moment this is what appears:
Windows PowerShell
Copyright (C) 2009 Microsoft Corporation. All rights reserved.

PS C:\Windows\system32> C:\Users\Jacob\ChangeCategory.ps1
PS C:\Windows\system32>

Is that what is supposed to be appearing? I have also realised that the script isn't changing Unidentified network into a home or work network, and it is still a public network.
Is my script incorrect? It is here:
# Name: ChangeCategory.ps1
# Copyright: Microsoft 2009
# Revision: 1.0
#
# This script can be used to change the network category of
# an 'Unidentified' network to Private to allow common network
# activity. This script should only be run when connected to
# a network that is trusted since it will also affect the
# firewall profile used.
# This script is provided as-is and Microsoft does not assume any
# liability. This script may be redistributed as long as the file
# contains these terms of use unmodified.
#
# Usage:
# Start an elevated Powershell command window and execute
# ChangeCategory.ps1
#
$NLMType = [Type]::GetTypeFromCLSID('DCB00C01-570F-4A9B-8D69-199FDBA5723B')
$INetworkListManager = [Activator]::CreateInstance($NLMType)

$NLM_ENUM_NETWORK_CONNECTED = 1
$NLM_NETWORK_CATEGORY_PUBLIC = 0x00
$NLM_NETWORK_CATEGORY_PRIVATE = 0x01
$UNIDENTIFIED = "Unidentified network"

$INetworks = $INetworkListManager.GetNetworks($NLM_ENUM_NETWORK_CONNECTED)

foreach ($INetwork in $INetworks)
{
$Name = $INetwork.GetName()
$Category = $INetwork.GetCategory()

if ($INetwork.IsConnected -and ($Category -eq $NLM_NETWORK_CATEGORY_PUBLIC) -and ($Name -eq $UNIDENTIFIED))
{
$INetwork.SetCategory($NLM_NETWORK_CATEGORY_PRIVATE)
}
}
Thanks again.

I thought that was the problem too, but I tried and still no changes.

Did you have the Ethernet adapter selected when you ran it?

That is the problem then. Sorry for the stupid question but how do I select it before running the script?

Right click on Network then go to properties. Delete all the tunnel adapters. Leave only Ethernet adapter Local Area Connection 2 and Wireless Lan 3. And restart the machine. The problem is hamachi VPN software you are using is creating many tunnel adapters.

I followed all the steps, even disabled all other network adapters to be sure, and checked again that it was top priority, but still no feedback from PowerShell and the network is still Unidentified and public.

I have also discovered that in Task Manager's Networking tab, I have two adapters called Local Area Connection 2. Could the problem be to do with them somehow? I only have one in control panel, but when I disable it, I still have only one Local Area Connection 2 in Task Manager.

Hamachi is disabled and I have tried the PowerShell script again, but still nothing. Still Unidentified, still public, still no network access.

Go to control panel, click on network and internet, click on network and sharing center, cilck on change adapter settings on the right side. Right click on Local Area connection 2, go to properties, select TCP/IPv4, then click on properties. Select "Obtain an IP address automatically" and below select "obtain DNS server address automatically".

Also, follow the above steps above but this time on your Wireless LAN adapter.

Make sure the hamichi and all other LAN adapters are disabled EXCEPT for Local Area connection 2 and the Wireless LAN adapter 3. Restart your machine.

I run the registry file, yet the Network is still a public one. It definitely says that it has been added to the registry. I'll see if a reboot will help and then reply here.
