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 ?
Your very welcome @miavespucci
Yes I have an intel 6235 wlan card dell service tag 88CCRY1 it receives 2.4 and 5.0 Ghz channels plus if you install a dell and note I do say DeLL intel 6300 n you can connect all three attennas for MiMO a better 5.0 Ghz experience
make sure the 6300 n from intel is a dell half height wlan card be aware intel markets a retail version
