I just got a brand new alienware computer (notebook) and I can access my
wireless network. But when i goto the Network and Sharing Center it shows the
connection between my notebook and my network -- labled "unindentified
network" but then it has a big red X on the line that goes to the World that
has Internet underneath.

I click on the X and run all the troubleshooting options vista offers.
Nothing works.

It only says that my Access is Local only. I would really like to understand
what I need to do.

I too ahve had a similar experience with a system recently. Interestingly it
only occurs on some networks. The machine in question worked fine on 3 of 4
home networks. I was stumped until I found this:

It suggests that its a bug which existed in the beta :(

Additionally someone suggested that the ipv6 layer be disabled (I haven't
tried this yet) as this isnt needed at the moment anyhow.

I have 2-Vista machines with me now. I am also having same experience. I am
not able to connect to Internet.

I tried disabling IPv6 option. But it didn't help at all. I am checking with
our Network Admin Team, the Router with SIP Enabled is causing the problem
and can we disable it and see what happens.

Thanks,
Vikas.

I have wired Gb to a Thecus N5200) and wifi to a NetGear DG834 router...
Recently my network has been misbehaving (a side-effect of a recent path ?) -
I CAN access local devices and the Internet but Vista says there is no
Internet connection, can't find anything wrong and disabling/re-enabling
(manually) adapters had no effect

On the basis of that IPv6 hint I turned it off on the wifi connection and
everything was instantly OK (IPv6 remains on for the wired LAN connection).

So, if you have network problems with no apparent cause and don't need IPv6
I would recommend experimenting to see what happens...

Thanks for the hint!

The issue is caused by a lack of a correct association on the SonicWALL
between the computer running Windows Vista and its assigned IP address.
Follow these steps to work around the issue by editing the System Registry:

Click the Start button.
Select All Programs > Accessories.
Right click (Command Prompt) then click (Run as administrator).
Type regedit.exe and press enter.
Go to the following location:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
Right click this entry and click (New) then click (Dword).
Rename the new entry ArpRetryCount (leave it set to 0 by default).
Restart the computer.
Retry connecting to network. You should notice a successful connection.

Hi zzzorrro,
I tried your fix but no luck.
Do you have anymore suggestions which could work.

Thanks in advance

Darren, I've used this fix on multiple laptops....it does work. Not sure why
you are still having a problem. Of course, you realize, microsoft in its
infinite wisdom did to the public again, what they did to us each time they
come out with a new system, try to force everyone to upgrade their hardware
(in this case their routers). Boy, wish I had invested in some of those
stocks before Vista hit the market.
Sorry, if my solution didn't work for ya. Again not sure why.

I can ping local resources not internet. I travel from site to site with my
lenovo T60P. If I uplug the network cable-even at the same site- I have to
refresh the adapter (properties/change something like PME or other function
not too drastic) to get access to the internet. I alsways get a DHCP Ok but
no internet. This happens with all different Sites using different
firewalls.

Today i ran in to this on a Dell Opt 745. It sat for a while and - broken
internet - local network OK. Refresh the network adapter- fixed.

I think this is a Windows Vista Security Bug- or a hidden phone home to MS
via some third party site- Figuring it's not lying by going directly to MS
;)

Lots of folks just reboot and don't post - this is a big issue out there
folks..


OK enough barging..

I'll try the ARP fix.. THX
