Disconnecting USB device causes Wireless network adapter to lose connection

Hagen · 04-23-2008, 03:51 AM

Hi Tech support,

I've recently installed Windows Vista x64 on my machine and used my motherboards built-in wireless connection to connect to my flat's wireless router. Everything worked fine until I noticed that whenever I remove a USB device from my front panel (USB Stick, MP3 Player) the wireless suddenly loses it's connection with the router, and the only thing I've found to fix things is a restart of my PC.
I also have a Laptop running a 32-bit version of Vista, and after trying it there it seems to have exactly the same problem.
Any ideas what's causing this, or better still how to fix it?

I am having the same problem for all my 5 computers.
They all have the same specs except for hard drive / disc drives and graphics card.

My temporary fix:
GUI:
Start Orb > Control Panel > View network status and tasks > Manage network connections > Select "Wireless Network Connection" > Disable this network device > Enable this network device

Command Line:

Code:

netsh interface set interface "Wireless Network Connection" DISABLE
netsh interface set interface "Wireless Network Connection" ENABLE

It's still not the solution to the problem, but it works when I need it. It does get annoying when I have to use USB devices and the Internet at the same time, though. This is why I want a solution to this problem.

hi XP1,

just to let you know, I seem to have fixed the issue by installing updated intel chipset drivers for my motherboard. I noticed that we have exactly the same motherboard, so presumably this is the reason for the trouble.

The chipset driver archive I used was:
Intel_ChipsetInf_v830113_includewin2003
downloaded directly from the ASUS website.

Hopefully this will also fix the problem for you.

I installed the driver from the executable: \Intel_ChipsetInf_v8301013_includewin2003\Chipset\Inf\Setup.exe

I tested the USB ports after a restart, but the USB disconnection problem is still there.

I downloaded the Intel_ChipsetInf_v8301013_includewin2003.zip file from http://support.asus.com/download/dow...=P5K-E/WIFI-AP under the Chipset category.

Here's the download description:

Maybe we can check the file hashes to make sure we have the right file?

From the motherboard manual:

Quote:

USB connectors (10-1 pin USB 78, USB 910, USB 11 12)
These connectors are for USB 2.0 ports. Connect the USB module cable to any of these connectors, then install the module to a slot opening at the back of the system chassis. These USB connectors comply with USB 2.0 specification that supports up to 480 Mbps connection speed.

I plugged in USB devices into my computer's front, top, and back USB ports. I found out that only the front and top USB ports were causing the disconnection problem, but the USB ports on the back do not have the problem.

The front and back USB ports connected internally are called USB1112 and USB78. From the manual (above), USB1112 and USB78 are 10-1 pin connectors on the motherboard.

I used the ASUS Q-Connectors to plug these USB connections in. However, I don't think this is the cause.

After looking at the ASUS website again, I think I gave you the wrong filename. I'm also trying to troubleshoot an unrelated freezing problem with vista and downloaded the previous file for this issue. Sorry about my confusion.

The driver archive is Intel_INF_V8301013_2kxpvista.zip, same Category as the first one.

Incidentally I also connected devices only to my front panel, also connected to the motherboard via the Asus Q-Connector. I'm fairly certain it's a driver issue, and EMI seems only a very remote possibility.

Ok, I downloaded and installed the Intel_INF_V8301013_2kxpvista.zip file.

I think this driver solved half of the problem. The problem still occurs but not as often.

I am on a Fujitsu Amilo Pi1505, Vista Home Premium and am having the same hassles. Every time you eject a USB flash it drops the Wireless LAN.

I have set IP to static,
Updated the Wireless LAN drivers,
Still no fix ...

Microsoft has suggested disabling IPv6, but I have not tried that yet.

I will also setup a link to the script you suggest to disable and re-enable the WLAN as an interim solution - a heck better than having to reboot each time.

Any other progress made?
I'll keep in touch.

Aliby · 06-09-2008, 01:38 AM

I am quite certain that it is not a Network compatibility issue.
I have done all the "standard" tweaks with no resolution to the problem:

Disable the IP Helper service
Disable IPv6
Disable the DHCP Broadcast Flag

What I have discovered is that it seems to be an issue with Vista's "Safely Remove Hardware" function.

If you just pull out your USB flash disk there is no loss of the Wireless Connection. However if you "safely remove" it then Vista drops the Wireless Network at the same time.

My only "Work Around" at the moment is to add XP1's script to DISABLE / ENABLE the wireless device, or I just pull out the USB flash disk.

Not sure if there is a way to report this with Microsoft? They seems to want to charge you to get onto any such forum ... or maybe they don't care?

I think this is more or less a Microsoft issue. I have an Asus Radeon Chipset Motherboard that it does it on, and an Asus NVidia Chipset Motherboard that this happens on. Also, when I eject a CD / DVD ROM from the IDE drive it disconnects the network.
