I'm working on a G73Sw (have 2 of my own also) - Win7 SP1 64 bit
More info at topic here: http://www.sevenforums.com/crashes-debugging/208325-bsod-most-likely-graphical-drivers-hardware.html

Problem is that we need to update/replace the Intel WiFi driver and it won't install for the user.
Anyone have any ideas about how to go about this?

It has:
a Kingston Docking Station
Intel(R) Centurino(R) Advanced-N 6250 AGN - PCI\VEN_8086&DEV_0087
Intel(R) Centrino(R) Advanced-N + WiMax 6250 - USB\VID_8086&PID_0186

Yikes! WAY too many devices! 🙂 What's the Hamachi thing? And why does he have a USB to ethernet adapter, since there's already on-board LAN?

I would uninstall ALL of those drivers. And then only when you're sure they're all cleared out, reboot and install the 6250 driver only...not the WIMAX stuff...and the Realtek LAN driver.

(By design, Intel drivers do not install over the top of old drivers. You must uninstall the previous driver before a new one will install.)

Hamachi is some sorta network software device (sorta like a VPN).
You find it a lot with LogMeIn and with USB AirCards (cell phone cards)

Dunno about the USB to Ethernet adapter - unless it's a part of the Kingston Docking station.

Why are there 2 6250 devices? and why is one PCI and the other USB?
Intel(R) Centurino(R) Advanced-N 6250 AGN - PCI\VEN_8086&DEV_0087
Intel(R) Centrino(R) Advanced-N + WiMax 6250 - USB\VID_8086&PID_0186


Uninstall which one of them?

Didn't know that about Intel drivers - will have to ask him to try it that way.

That card has both Wi-Fi and WIMAX capabilities. The first listing, under network adapters, is the wi-fi component. The other listing is the WIMAX device....it's under "Other Devices" because there's no driver installed. If it's not used, just disable it.
