ipconfig and network connections empty - Device Manager okay

Hi,

I just got confronted with an WinXP system (IBM T40, build-in WLAN and
LAN) which had a problem. The problem seemed to coincide with the
installation of a noname(Tchibo)-USB-Webcam, which was deinstalled
there after.
The following is the problem:

Both network cards (intel wlan and intel lan) are listed in the device
manager as being okay. Drivers installed okay. "IBM connection
manager" is not installed.
Both cards are activated via the BIOS and the WLAN light signals that
the card is active.

however:
ipconfig just replys "windows IP configuration". No adapter is
listed.
Network connection is empty.
Trying to install a connection gets one to a screen where one can
choose an adapter to establish the connection. The list to choose from
features only the wlan card not the lan card and says about the wlan
card that the installation can't procede till on would have activated
the card again.
The simple ip services like ping aren't installed but I don't see what
I need them for? Does one have to install them in order to get any
internet connection and to get the adapters listed?
Pluging in a LAN-cable with a DHCP host on the other side won't make
ipconfig or "network connections" show the ethernet adapter.
I couldn't establish a connection to the ethernet.
The WLAN/Bluetooth activation software started when clicked "FN+F5"
just lists the Bluetooth adapter which can be activated and deactived.
On pressing FN+F5 the software comes up and complains that the card
can not be activated. (this doesn't seem to be a wlan problem however
as the wired adapter isn't showing up (other than in the device
manager) either.)


Do you maybe have an idea, what the problem might be?
Thanks alot,
Jack
 
Have you confirmed that all of the necessary services associated with
network connectivity have started?

Confirm that the Plug and Play service, Network [and Dial-up]
Connections service, and Remote Procedure Call (RPC) service are all
running. [Start > Run > services.msc (click OK)]

If there is no icon showing in Network Connections, it means that:

• The network adapter was removed. (A local area connection only appears
if an adapter is detected.)
• The installed network adapter is malfunctioning.
• If your network adapter is a legacy adapter that is not detected by
the Add New Hardware wizard or the Plug and Play service, then you might
need to set up the adapter manually in Device Manager before you see a
local area connection in the Network and Dial-up Connections folder.
• If the driver is not recognized, the adapter appears in Device Manager
but you cannot see a local area connection.

Where did you get the drivers from that you said, "installed Okay"?

Thanks for your answers so far.

Unfortunately, I don't have the laptop with me right now. Anyway, I'm
not sure how to proceed from your mails. So I'll first answer your
questions and maybe you'll have another hint for me.
Where did you get the drivers from that you said, "installed Okay"?

By " Drivers installed okay. " I just meant that I look in the device
manage whether there where some drivers installed and there were. Not
problem was signalized by and warnings and both drivers were by intel
and signed by ms. unfortunately, I don't remember the exact version. I
once installed the computer some one or two years ago and it seemed to
have worked till three weeks ago. As far as I understood the owner he
didn't install any network drivers for either the lan nor the wlan
adapter when the problem occurred. The drivers I installed two years
ago, I got from either the intel or the IBM page and I executed the
IBM update utility afterwards which in turn downloaded several updates
from the IBM page which I installed those two years ago.

Before posting here I read
http://support.microsoft.com/kb/825826
as it was closest to my problem. However it differs in the important
degree that in KB825826 the network connections _are_ working and just
aren't shown. Here the network connections won't even display via
ipconfig.
Confirm that the Plug and Play service, Network [and Dial-up]
Connections service, and Remote Procedure Call (RPC) service are all
running. [Start > Run > services.msc (click OK)]
Click to expand...

We did the first four point from KB825826 before we went out of time
today. So we checked that
• Remote Procedure Call (RPC)
• Network Connections (this service depends on RPC service)
• Plug and Play
• COM+ Event System (this service depends on RPC service)
• Remote Access Connection Manager (this service depends on Telephony
service)
• Telephony (this service depends on RPC service and on PnP service)
where running (though some of them were set to be called "manually")

Anyway, I guess that KB825826 doesn't describe my problem as it says
that ipconfig should give a feedback other then just the one line:
"Windows-IP-Konfiguration".

I guess more over that it can't be problem with the drivers of the
cards as both wlan and lan stopped working and so it seems to me that
the problem isn't connected to a specific adapter and therefore not to
a specific driver.
If there is no icon showing in Network Connections, it means that:

� The network adapter was removed. (A local area connection only appears
if an adapter is detected.)
� The installed network adapter is malfunctioning.
� If your network adapter is a legacy adapter that is not detectedby
the Add New Hardware wizard or the Plug and Play service, then you might

local area connection in the Network and Dial-up Connections folder.
� If the driver is not recognized, the adapter appears in Device Manager
but you cannot see a local area connection.

I'm not sure, how to act on this. The network are adapters weren't
removed as far as I saw it (in device manage and bios), especially not
both of them. It might be that the adapter is malfunctioning but why
would wlan and lan card do so at the same time? The adapters are part
of centrino (at least the wlan, I'm not sure whether the intel lan
chip is part of centrino - anyways it's intel and in an ibm laptop
that isn't sooo old), so I suppose they don't fall into the legacy
category.
Maybe the last point is the one. But I don't understand it completely.
How could a driver not be recognized? How can one change that? (Again,
the one installed is a ms-signed intel driver)

I appreciate your help and I'd be happy if you could share some
further insight into the problem,
Jack

Try UNinstalling one of the adapters (e.g., the LAN adapter) from Device
Manager. Then re-boot. Windows should discover the "new" hardware and
install it. If there are any error/warning messages, try to write them
down.

I just heard back from the owner of the laptop. He uninstalled the lan-
driver and without him even noticing the driver got installed again
and the wlan started to work again.

Thank you, very much.
