We have just purchased brand new DELL Latitude E6410 and E4310 for our company. This is the first time we've purchased this new model.
We normally use Acronis imaging to image our machines. Since these DELL machines came built in with their own partitions and software (Latitude ON which we don't use), we decided to format it with a volume license Windows 7 CD and reinstall all the drivers and software.
Everything went smoothly and we completed setting up 2 x E6410 and 1 x 4310.
However, we noticed that the wireless network card, although enabled and active, was not able to find any Wireless networks. The same symptom was seen by ALL 3 laptops.
We had one more brand new unopened E4310. Out of curiousity, we decided to install the built in image that came along with it, and the WiFi works fine on that.
So this is really confusing. We installed the correct drivers, the WiFi is enabled from the BIOS (we didn't even touch the BIOS) and the switch is on.
There is an INTEL PRO SET WiFi diagnostics test tool which i ran on the problem machines. It straight away fails the first "Hardware Test", saying that either hardware is not enabled or switched off. However, it does pass the "Driver Test", so I'm quite certain it's NOT a driver issue.
Any ideas on what could be causing our fresh install to make the WiFi unable to scan Wireless networks?
