Cannot create or connect to ad hoc network

[Earl]

This related to a Toshiba Satellite U305-S5077 laptop running Vista Home
Premium
with an Atheros AR5007EG Wireless Network Adapter. Trying to create an
ad hoc network fails with no indication of the reason. Trying to connect to
an
existing network fails with an Error log entry of
"failed due to an unknown reason".

I have been using ad hoc networking between two other Vista systems without
any problems.

The wireless adapter works and has current drivers.

Any suggestions on what else to look at?
------- Details ------------------------------------------------------------

When I try to set up an ad hoc network named WW, it fails and gives the
message
"Windows could not set up WW".
I can't find anything in the Event Viewer that seems to correlate with the
failure. I've tried different network names, different Security types but
nothing works.

It will detect an existing ad hoc network named WW but will not join it.
It gives the message:
"Windows cannot connect to WW"

The Network Diagnostics Events Log entry is
"

hardware manufacturer for further assistance.

Trying again gives the same results.
The Device Manager claims the Wireless Network Adapter is working
properly and that the driver is current.

Have a read of the above link re Vista File and Printer Sharing.

Permissions/Share info is there as well.

If using Norton, McAfee, Trend Micro I.S., make sure file and printer
sharing is enabled in THEIR firewall.

1st thing to do is make sure that the Workgroup Name of ALL the computers is
the SAME.

In Vista Network and Sharing:

Network Discovery: ON (So it can see the other computers)

Network set to Private (Public is for hotspots, airports, etc)

File Sharing: ON

Public Folder Sharing: ON (Vista’s Public Folder is the same as XP’s Shared
Docs)

Password Protected: OFF (unless you want to set up identical usernames and
passwords on ALL computers in your Network) If you have it ON, you will be
asked for a username and password when you try to access a Vista computer
from an XP computer.

Thanks for your response.

I think I could get file and print sharing to work if I could
connect to a network. When I connect with a Lan it works.
When I try to use a wireless network, I can see my existing
one listed, but get “failed due to an unknown reason.â€
when I try to connect.

I connect to it regularly from other systems. The password is
right, the adapter should be able to handle the security level.
I thought there might be some other incompatibility, so I
tried to create a new network from this system. It just says
“Windows could not set up WW†with no indication of why.

Workgroup name, accounts/passwords, permissions, and
firewall settings are the same on this system as the ones that work.

I think the problem is happening before authentication happens.
I thought it might be hardware or driver problems. But, the
device manager doesn't show a problem and likes the current
driver. I see the same wireless networks as the other systems
show. I just cannot connect to them.

I am just looking for some ideas about what to investigate next.
What could prevent me from creating or connecting to a network.

Thanks,
Earl

I have exactly the same problem. I have a Toshiba Satellite laptop
with an Atheros Wireless Card and receive the same problem when I try
to connect to or create an adhoc-Network.

Have you solved it?

I never could get ad hoc networking to work. We got a wireless router and
and the laptop connects to it with no problems. Its irritating to not get
the ad hoc net to work, but the router network is much easer to use and more
reliable.

But, I would still like to know why it doesn't work.

I had the same problem with my satellite A200's wifi card (Atheros
AR5007EG). I think the problem comes from windows update installing a wrong
version of the driver. So I just tried to restore the previous driver
(7.3.1.42) and things worked fine again !!
Hope this will help

Since recently there is an updated driver on the Toshiba-homepage.
Works for me!
