nwifi.sys Vista BSOD, TPLink WN350GD + Sagem XG-762N

DustieDustie · May 14, 2011

Problems started a few weeks after installing a TP-Link wireless PCI card, TL-WN350GD. At first Internet worked fine, but then I noticed I get connection blackouts that last from a few minutes to some 15 minutes or more. I asked my roommates who run Vista on a laptop and also use wi-fi, they said everything was fine with their connection, so I couldn't blame the router in our flat anymore (which I thought might have been the cause at first).

I thought the fact that the card was in the back of my PC, which was against the wall in a corner of my room, while the router is in the other room, doors to both of the rooms being closed most of the time, was the main problem causing connection blackouts, so I started fiddling with the card's antenna position, but there was minimal improvement.

About a month ago I brought a USB modem originally used with Poland's local telecom provider (the service is called Neostrada), Sagem XG-762N, and tried using it for wi-fi instead, and it seemed to have improved my connection as blackouts have become less prominient, which I thought was thank to the modem being placed in the USB slot on the front of my PC, thus being able to pick up signal easier. In order to get connections in Vista sorted out, I simply disabled the TP-Link PCI card in Device Manager, in the Properties card.

Everything was close to fine until last evening: Vista crashed with a BSOD while I was watching a video on Youtube. The file named was nwifi.sys and all else I saw was the counter saying something about memory dump and counting to restart...

Afterwards Vista would boot, but would crash while on the Welcome screen, a few seconds after showing the 'ring' cursor spinning. I finally got it to run in Safe Mode after removing both the USB WiFi card and TP-Link PCI card.

I made a HDD check using Checkdisk, it didn't pick up any errors.

I followed BSOD-error posting instructions, but the W7/Vista EXE tool got stuck at Waiting for SystemInfo message (it kept on repeating that for a good 15 minutes after the 'Almost Finished' message), so I just switched it off and zipped up what it produced in the folder (plus the PERFMON report in html format).

I got Vista up-and-running right now as I'm writing this, in normal mode, except the cards are still disconnected. I will try hooking up the Sagem USB WiFi after posting this and see what happens...

Vista Home Premium 64-bit
This was the original OS installed, it seems to be OEM version, as it came pre-installed.
2 years old.
I haven't reinstalled the OS since I got the hardware.
Athlon 64 X2 7750 2,7GHz
NVidia GeForce 6150SE nForce 430
Gigabyte M61PME-S2P
I can't recall at the moment, but it's 400W, possibly Corsair

While not a major problem, there's only 13% free space on your hard drive. I suggest keeping 15% free for optimum performance.

2gB of RAM is barely adequate for Vista versions other than Basic. I suggest getting more RAM. If that's not possible, then prune out the startups on your system (using the Autorun program that you've already downloaded) and only run one program at a time. This will make the system a bit more responsive.

Please install this nVidia nForce chipset driver (to update your Ethernet drivers): NVIDIA DRIVERS 15.49 WHQL

Also, please update the software for your Thomson DSL modem/router - as it dates from 2005! Here's a link to the Thomson website, but you may be able to get drivers from the Telekom people. DSL Modems & Gateways - Product Range

Then update the drivers for the Sagem USB device (if still using that) - although they aren't as outdated as the others.

OLDER DRIVERS PRESENT IN THE DUMP FILES
- Create a System Restore Point prior to doing any of this. DO NOT mess with the drivers themselves - leave the Windows\System32\drivers directory alone unless we specifically direct you to it!
- Please update these drivers from the device manufacturer's website - or uninstall them from your system. Reference links are included below.
- DO NOT use Windows Update or the Update Drivers function of Device Manager.
- Please feel free to post back about any drivers that you are having difficulty locating.
- Windows Update exceptions may be noted below for Windows drivers:

Thank you for replying to my issue :smile:

The Thomson device is no longer in use - it was used with an ISP I'm not using anymore, so I'm just going to uninstall the drivers/software package that came with it.

As for the disk space - I'll deal with that too.

After removing the PCI WiFi card, everything went back to normal. I have also managed to find a good place in my room where the signal is good enough and the connection is fine at last, which indicates it wasn't all just internal Vista-WiFi issue. Since I'm in the midst of writing my diploma, I prefer to wait until I'm done with that before I make any updates and changes.

I will keep you posted :wave:
