Hi Jake,
Thanks for replying.
The Wireless Card is called "Intel 8260/7265/7260/3165/3160 WiFi Driver" on the Dell Support site related to my Support Tag.
I was semi-expecting to have to replace the wireless card as it looks like no Intel WiFi Cards are supported which I'm okay with, I tried plugging in a USB Wireless Adapter however that wasn't appearing on the OS and wouldn't let me connect to any networks.
And with regards to the battery, the battery is showing as Not Available and wasn't able to provide a "charging/not charging" symbol or a percentage.
