New Bluesound's Node 2i

I have a Node2 connected to a Schiit Gungnir Multibit. 90% of the time it works great streaming from my Synology NAS using Roon. My problem is my main listening room is upstairs and the furthest from my router. All my other Bluesound products are closer and really never have issues. But my Node2 struggles at times with dropouts. Especially with higher-res files (like 24/192.) I wonder if just the improved wifi alone in the 2i would solve this? Obviously I don't care about the DAC inside, just the connectivity issue. I could probably hire an electrician to run CAT6 cable up here and install a jack to plug my Node2 into for about the same price as buying a 2i. But maybe the dual-band 802.11ac (which my router provides) would do the trick. What do you think?
