New Dell Inspiron 3520 Win 7 does not recognize wireless

Wednesday 12-12-12, purchased a Dell Inspiron 3520 with Windows 8. Installed Win 7 Home Professional and downloaded drivers for network communications. All loaded except Network Controller & BCM43142A0.

I have tapped Fn + F2          (to turn on wireless)

Device Manager has a yellow ! on these.

Trying to update driver over Internet or HDD gets = Windows could not find driver software for your device.

When I go to Network locations to connect to a network, it says, "No connections available".

When I click properties for "Network Controller", I get PCI bus 7, device 0, function 0,

No driver selected   Code 28

Laptop only works with wired connection

Any solution to this

I use a secure wireless network at my home, so need to enter my new dell Inspiron wifi address into my router system. Where do I find this (file) on the computer. I located the blue tooth address but can't determine wifi or MAC address. Thanks for any help you can offer.

Re: New Dell Inspiron 3520 Win 7 does not recognize wireless

I found solution!!! The problem was with Windows 7 switching off wifi for power saving.

You need in adapter "Settings -> Power Management" tab to remove mark near option "Allow computer to turn off this device to save power"

Screenshot from here (Used it because I'm not from US and have different language) but it's the same option for everyone.

Solution remembered from other problem I had with other wifi adapter.

After this for power saving for wireless will be off, but it's always better to use hotkeys combination whenever you don't use wireless and work on battery.

This was a solution for Dell Inspiron 3520 with OS Windows 7 x64. But I think it can fix for the same device and normal drivers on any system 🙂

That will not work if the wireless card is not found. What worked for me was (downgrade from 8 to 7 64) for an Inspiron 3520 go to the downloads page

Make sure you install this from the modem comm section
