Sybu remote through gig switch

Hi all, I am running Jarvis and I was running it over a wireless network. It was too slow, I was losing serious bandwidth through the wireless router so I decided to connect the computer to a gig switch then run from that to the computer running kodi, the wireless router to provide wifi in the house and to other media devices like to the smart TV. Now there is no remote, If I connect the computer to the Ethernet port on wireless router it works but again the bandwidth drops by 2/3rds Is there a work around for this?
