Wireless Networking NIC Causing Laptop to Lockup?

A few months ago I moved into a new house and wanted to have a wireless network for my laptop.   I’ve had no problems at all until a few weeks ago.  The laptop would just lock up for no reason while I worked on it.  After weeks of trying to figure out what the problem was. I formatted everything and reinstalled all the preinstalled software that came with it.  I then installed SP2 and any new Software updates for my wireless NIC, but it’s still giving me major problems.  Since then I have uninstalled SP2.

Here is what I have…

Toshiba Satellite P25-S477
XP Professional
Netgear WG511T

I currently am using the wireless nic that came with the laptop to connect to my wireless network.  I am limited at 10 Mbps when I do this.  I would like to be able to use the fast 108 Mbps connection.  Can anyone give me some tips on how to fix this?

Sometimes the laptop will lockup, then when I reboot, the laptop does not recognize that the wireless netgear NIC is not installed.  I would have to uninstall the NETGEAR WG511T Smart Configuration software then reinstall it and it would recognize the NIC again and jump on the network.  How can I fix this problem?

What exactly do you mean by lock up , lockup of applications or internet connection ?

Without internet , is your laptop working fine with no issues..

Have you tested your wireless connection using an external wireless card and does it show the same locking behavior ?

Do you have problem even without SP2 or only with Sp2 ?

Is your netgear wireless router got the latest firware version ?  

Have you tried to reset your router and test if the connection would be fine ?

Try to scan for virus and spyware in your laptop and make sure those are not creating any issues ?

My complete computer locks up.  Even when I reboot and windows is going through it’s normal boot up sequence, it will lock up.

When I yank out my wireless nic the laptop is working fine with no problems.

The problem is when I do use a wireless nic, the computer really has problems.

Yes, I had the problems with SP2.  I installed SP2 when I reinstalled all the software and the same problems occurred.

I have reset the router a few times, but I really think it’s a wireless nic / driver issue.

No, I have not upgraded the latest version of firmware on the router itself.

I’m pretty sure I have no virus.  I have the latest Norton’s anti virus as well and scan and update once a week.
I would see if the problem exists doing 3 things

a) Uninstalling SP2

b) upgrading the firmware of your router

c) Checking the wireless NIC has got the latest version

Sp2 is uninstalled

I have the latest version of my wireless nic software installed.
do you have an external wireless card right ?

My laptop came with an internal and an external.  I have a Netgear WG511T external wireless card.  So, the answer to your question is yes.

Sorry, I meant it came with an internal and I have purchased an external one.
Try this then

open command prompt and give this
set devmgr_show_nonpresent_devices=1

then give this "devmgmt.msc"

Device manager should open.
Donot close the command prompt.
IN the device manager , go to view > show hidden devices.

Now go to network adapters and you should see your network card name there. Remove the existence of all the external wireless network cards you see there.
reboot and then install your card fresh..

Check if that would help


"I have found that the 3.1 driver set from NetGear's web site works pretty well for me, but anything newer exhibits the system freezes. "  As from within this thread.

It may be that the older drivers in this case are better.

SP2 should be fine.  I assume Anti-Virus is disabled when you install the software for the card.  

What you should do, is uninstall all traces of the netgear stuff, get your machine to a state that you are satisfied is stable.

Download the drivers as mentioned in the above forum.  Disable AV, and try again.  

If you are still running into problems, you may want to try and rebuild from scratch, not using the factory rebuild.  Actually from scratch, format discs etc.  Either you have a hardware fault at this point or a software one, and you need to eliminate the factory build as a potential software area.

As for the speed, I don't know this software, so can't say but it seems that this is a common problem.
check your event log it will tell you what the problem is, let us know, start/control panel/admin tools/event log.

Similiar problem happens to me.
Finally i conclude that the PCMCIA port of laptop is not working fine with some wifi cards. When i changed card with different model lock-ups stopped. Don't know if this is compatibility problem but this will require MUCH of the investigation to show what's wrong.

Please keep this post up.  I was away traveling and when I got home my LCD on my laptop had been cracked and is now broken.   Good luck eh?  I plan on ordering a replacement part but that might take a few days.
It appears that on some laptop models have bad power supply for pcmcia that could cause card to stop responding (laptop also). Some cards draws much of the power from the laptop and this could be one case. Changing the laptop (motherboard) or card is almost only solution.
