art-net noob question

Hi!

I'm considering getting into art-net, my only issue is that I'm using Onyx and my laptop doesn't have an ethernet port.

Could I use a router connected to an art-net node for a wireless setup, or would I be better off looking into some kind of USB to cat-5/ethernet adapter?

My thoughts are that a wireless setup would be better so I can move around while programming, but if there's a lot of latency that could be an issue when I'm running shows.

Thanks!
