Q: presentation remote mac mini only works sporadically
Hi all,
I have a Logitech R400 that needs to be able to control PowerPoint presentations on a Mac mini.
Yesterday, it worked fine.
Today, it only works sporadically and I haven't changed a thing. It's the same presentation even.
Sometimes you can change the slide and sometimes you can't (even when standing very close to the Mac mini).
The specs on this Mac mini are pretty anemic (1.4 GHz and 4 GB memory) but I've closed all apps except PowerPoint and have almost 2 GB free memory.
Any thoughts?
Any help would be most appreciated!
Mike
Mac mini, OS X El Capitan (10.11.6)

Based on

the remote uses a USB wifi dongle and operates on the 2.4 GHz band.
That band is susceptible to interference and I suspect that is causing your problem.
USB 3 devices is one source of interference.
Try using the dongle at the end of a USB extension cable
