Hi killerkilley,
You may update the system BIOS from the link: http://dell.to/146fd8j.
You may check in ‘Device Manager’ which wireless card you are using by following the steps below:
- Press ‘Windows’ key + R on ‘Desktop’ screen
- Type ‘devmgmt.msc’ in run box and press ‘Enter’
- Click > sign next to ‘Network adapters’
Please paste the screenshot of ‘Device Manager’ if possible.
Keep me posted with the information. I will be glad to assist further.
