Wireless network connection drops

[jglennt]

I have a small office wireless network; as of last week, we have two
computers with Vista Business and two with XP. The Vista computers
periodically lose the network connection; the XP computers do not. When you
attempt to reconnect the Vista computers, the repsonse is "Windows cannot
find any wireless networks." You can see, on the XP and other Vista computer
that the network is up and running strong. A reboot restores the network
connection; suddenly after a reboot, Vista sees the network, and 5 or 6
others that show up in the locality. When it loses the connection, it sees
nothing (until a reboot). Help, anyone???

Sounds like faulty drivers for the wireless. Try getting an update from the
manufacturer.

In the mean time, try rt-click and "Repair" instead of a reboot. This will
give you close to the same thing as a reboot but only for the wireless
device.

I have already tried right clicking, and selecting repair. No effect. the
response is "Windows cannot find any networks." Only rebooting seems to
restore the wireless network connection.

Thank you. I'll try updating the drivers.

Hi,

Are you using any kind of security on the wireless connection? I used to
have this problem until i started using WPA2 encryption and then it worked
fine.

Yes, we are running a secure network connection, like the one you describe.

I have the exact same problem. I have updated my network adapter to the
latest vista driver. My router is vista compatible. I have disabled all
sleep modes on the computer and network adapter. The repair option does not
correct the problem. Only a reboot resolves the issue. And while this is
happening the Windows XP systems are working perfectly.

I am experiencing the exact same problem on my new Vista computer (drops network, can't find it again and restart is only solution).
It would really help me as well if anyone can find a solution, thank you!

How are you connected to the Internet?

If by router, get latest Vista Firmware for it.
Also, get the latest drivers for your Network Adaptor.
And, right-click on Network Connection>Properties>disable TCP/IPv6

Thank you for your help. But I have just recently found a solution elsewhere;
In device manager I opened the properties of my ethernet device and turned off the power-saving mode that vista defaulted it to- meaning that vista will no longer shut it off due to being idle!
