Ipconfig problem...too many Tunnel adapters

[biostudent]

Here's the situation:
I needed to access my wireless connection's Description and Physical Address, but ipconfig gave me some really strange output. I can't find my Wireless connection anywhere, which is strange because I use it at home all the time. I don't know very much about computers, but I know this isn't right. The screen just displayed 58 (yes, 58) Tunnel Adapters that look like this:

Tunnel adapter Local Area Connection* (number)
Media State.................:Media Disconnected
Connection-specific DNS suffix:
Description...................: 6T04 Adapter
Physical Address............: 00-00-00-00-00-00-00-E0
DHCP enabled................:No
Autoconfiguration Enabled: Yes

or like this:

Tunnel adapter Local Area Connection* (number)
Media State..........................:Media Disconnected
Connection-specific DNS suffix.:

I don't even know what Tunnel Adapters are. Why so many of 'em? And MOST importantly, why can't I find my ethernet or wireless connections on ipconfig or ipconfig /all, even when wireless is turned on? Can anyone help me? Just in case, my operating system is Windows Vista. Please help

Well, it would have helped if you posted the entire IPCONFIG /ALL.

Let's start with some basic configuration changes, maybe we can get rid of all of them, since you almost surely aren't using IPv6 yet.



Disable the IP Helper service:

1. Hold the Windows key and type R, enter "services.msc" (without the quotes) and press Enter
2. Scroll down to the IP Helper service, right click on it and select Properties
3. In the dropdown box that says "Automatic" or "Manual", set it to Disabled and then click on "Apply"
4. Then click on "Stop" to stop the service from running in the current session
5. Click OK to exit the dialog



Disable IPv6:

1. Hold the Windows key and type R, enter "ncpa.cpl" (without the quotes) and press Enter
2. Right click on each network connection and select "Properties"
3. Remove the checkmark from the box next to "Internet Protocol Version 6 (TCP/IPv6)
4. Click OK to exit the dialog

NOTE: You should do this for each network connection.



Disable the DHCP Broadcast Flag:

1. Hold the Windows key and type R, enter regedit and press Enter.
2. Locate and then click the following registry subkey:
3. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
4. In this registry path, click the (GUID) subkey to be updated.
5. If the key DhcpConnForceBroadcastFlag does not exist, use the Edit menu, point to New, and then click DWORD (32-bit) Value. In the New Value #1 box, type DhcpConnForceBroadcastFlag, and then press ENTER. If the key exists, skip this step.
6. Right-click DhcpConnForceBroadcastFlag, and then click Modify.
7. In the Value data box, type 0, and then click OK.
8. Close Registry Editor.

NOTE: You should do this for each and every GUID subkey.
NOTE2: (GUID) is a mnemonic for the individual subkeys, the actual text "GUID" does not appaer.




The only program I'm aware of that currently relies on IPv6 is the new Windows Meeting Space. The first 2 changes will cause that program not to work - but will leave all of your normal (IPv4) connections unaffected. If it causes problems that you can't overcome, simply revert back to the original settings.










After that, please do this.

Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

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.

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.
