Keynote Remote disconnects and lags when using with iMac

I have an iPad with Keynote that I use to control a presentation running on an iMac in a media room. The Mac and iPad are connected to the same router and network and the displays are hardwired to the Mac, so I'm not using AirPlay. However sometimes when advancing to the next slide there a few second delay before the transition starts and sometimes it skips the transition effect all together and just jumps to the next slide. In addition to this sometimes the remote will disconnect from and we have to hit play presentation again on the keynote app for the iPad. The router, iMac, and iPad are all within 30ft from one another with no wall obstructing the signal. We have a Netgear Nighthawk Router and Fiber internet running 300Mbps. Any ideas on wby this could be happing?
