Best router for 2 Xbox connection

I have two sons and each has an Xbox One.  I have both of the Xboxes wired to my existing modem via a switch.  This is not working at all due to Xbox issues with having 2 connected at once.  Only one can get on at a time.  

I would like to upgrade to a new router that would allow both Xboxes to be connected by wire and used at the same time.  Looking for recommendation of best one to chose.  We also have multiple TVs connected to wi-fi and streaming.  I have heard good things about Orbi, but not sure if it works well with two Xboxes connected by wire?  Do I have to go to a Nighthawk?  

If needed for reco, my modem is from Spectrum and is an Ubee model DVW32CB.
