5 Ghz on Latitude E6540

Welcome to the Dell Community  @miavespucci 

Yes you can.

If you want to connect now we would need the model number of the WiFi card you have installed now???

If you do not have a card installed that supports 5GHz you can upgrade to one that does.

One that I use for your model laptop is Intel® Dual Band Wireless-AC 7260.

You have drivers for this model WiFi on your Driver Support page.

Note: Click on the WiFi symbol in the lower right hand corner.

If you see any Networks with the extension -5G then you have a 5GHz WiFi card already installed.

Hi I opened the laptop the card inside is 

Dell WLAN WiFi Mini-Half Wireless Card 802.11 b/g/n 0MNRG4 DW1506

does that have the ability to connect to 5Ghz ? 

Thanks, Mia 

Thank you
