Bluesound node 2i question

Thanks in advance everyone !  Ready to buy one of these so I called a store in town to see if they have it in stock.  The sales person asked about my router/modem and I told him I use the router supplied by my internet carrier: Century Link.  When I told him I would be connecting to it via WiFi the salesman proceeded to tell me that I would have drop-outs and other issues I really didn’t understand...I’m a newbie to this as I’ve collected records for decades.  My question:  is anybody using a bluesound node 2i with the basic set-up received from your internet carrier ?  How does it work ?  He obviously could have gone ahead and sold me one, so his warning has slowed me to a stop...
stereo i plan on using it with:
Mesa Tigris amp
coincident conquest speakers

oh, and. I still love my Allnic 1201 phono pre and Funk LSD turntable..😏
