Hello,
I hope you are all well.
I have a dell latitude E7450 with the following wifi card: "Intel Corporation Wireless 7265".
Although this is an AC card, iwconfig reports "IEEE 802.11abgn".
I don't currently have an AC router. Is there a way to check if the linux drivers are AC ready?
Same behavior under 16.04.
