network card options

I currently own a Mac Book Pro and am able to receive an internet signal without a router as I'm located in a public hotspot. The Mac came with an AirPort Extreme Wi-Fi wireless network card based on IEEE 802.11n spec. and is backwards compatible.

I plan on purchasing the XPS 15 and wondering if I'll be able to connect as easily with this system, and if it makes any difference which wireless card I use. Options are the N 1000 or the Advanced N 6200 for $30 extra.

Thanks,
