Perfmon reports 10 NIC's?

Hi guys,

I am currently analyzing a BSOD post, and the perfmon for this specific case reports the following:

High average interrupts / processor. This machine has 4 processors and 10 network cards. Total Interrupts/sec on the machine is 68235. The average interrupts per processor per sec is 17059.

10 network cards??? What does this mean? I asked if they were virtualized (only thing I could think of) and the OP responded with:

My wireless network adapter (TP-Link WN822N) shows up as Wireless Connection #10 however I can't see wireless connections 1-9 in order to disable them, is this possible?

Can anyone steer me in the right direction? I've never seen this before.

Regards,

Patrick
 
Did he enable hidden devices in Device Mgr?

What shows up in other files like msinfo32, systeminfo, etc... for networking?
 
Ask him to check in for greyed out devices in DM after enabling hidden devices in Device Manager, it rather sounds like a driver is loading for each USB port it's been connected to?

Maybe it fails and troubleshooting then repairs it as a new # each time? If it's happening on W7/8 x64, it could be that it's older hardware with Vista -era drivers, buying new hardware with recent drivers is the best fix for that.

To remove the old devices from DM usually requires a reboot immediately on applying/hitting the OK button - makes a very long job of removing them all.
 
DirectX report shows Ethernet -
Code: 
     Name: NVIDIA nForce Networking Controller
Device ID: PCI\VEN_10DE&DEV_0373&SUBSYS_CB841043&REV_A3\3&2411E6FE&1&88

     Name: NVIDIA nForce Networking Controller #2
Device ID: PCI\VEN_10DE&DEV_0373&SUBSYS_CB841043&REV_A3\3&2411E6FE&1&90

OP has a 75 GB SSD -
Code: 
INTEL SS DSA2M080G2GC SCSI Disk Device

And a 3 TB HDD -
Code: 
ST3000DM 001-9YN166 SCSI Disk Device

Firmware upgrade if available for SSD may help.
 
I'm guessing they also have a nVidia chipset? I tend to see those chipsets cause frequent problems, maybe a chipset update may help?

You guessed correctly! I asked the OP to update the drivers and they did, so I will request another perfmon to see if it has been solved.

If not, I will go through everything else mentioned here. Thanks a lot guys!
 
If this user has either created an ad-hoc wireless network or joined a homegroup, then you'll see that virtual wifi miniport (there may be other ways, but those are the most common). If that WiFi connector is a USB device, and the computer presents it differently during different boot cycles (not impossible - this problem can even exist on servers, where teaming can be broken, for instance), Windows has to create a new miniport device to bind to the wireless NIC because the "old" one has disappeared, and the "new" one is such because the GUID changed due to it being presented differently than the last time to the OS.

If you add up 1 wireless NIC, 2x physical NICs, and 7 virtual miniport adapters, you get 10. This is what is happening most likely, given that wireless device is a USB device and not built-in.
