Gateway E475m - Wifi connectivity

[Justin]

I have a Gateway E475m running Windows 7 64 bit.
I got the wifi working fine - until a few days ago. I replaced the
pci-e wifi adapter with another one and I still couldn't get a
connection.
I tried a restore and I got my network settings back but still no
connection.
I tried swapping the antenna leads - nothing.
Did the pci-e port blow?
Here are a few screenshots and a picture of the installed pci-e card.

You could also use Everest Home Edition, and see if there is a 8086:4227
on the bus. That would prove the PCI Express interface is being detected.
You'd look under DevicesCI Devices (as PCI Express is an instance of PCI).
Since this free version is an old program, the Intel network device would
show up as "NoDB", meaning the program cannot name the device as 3945ABG.
The main purpose of using Everest, would be so you can check for the
8086:4227 part yourself. (Note - I tested Everest on Win7, and it only
moans a little bit about "unsigned driver".)

This is "lspci -vvnn" from Linux. The "03:00.0" is presumably some identifier
of what bus address the thing is at. Your laptop could have a different
value for that. This is how you'd check from Linux (if, for example, you
used Linux for hardware testing, to prove the thing was dead or alive).

03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:4227] (rev 02)

This is where I got a double check on 4227.

Absolutly no effect whatsoever.

I have the latest driver installed, and I still don't even get a wifi
LED. I confirmed the stinking switch is on as well - there I have a
LED, but for some reason the radio just won't turn the hell on.
Why would this happen on two different adapters?

Can you used System Restore, to go back to a time when it was working ?

After you've tried that, you can have a look at this "Manual Diagnostic".
