Your transfer speeds are maxed by your ISP. Checking you actual speeds depends on the server. Most speed checks will give you options to what server you wish to connect, like NYC, Morgan WV, and so on. Lots of things factor into real modem speeds. I always check a number of speed check sites and record them on a spread sheet for past 10 years. Xfinity is my provider and I pay extra for high speeds, but have planned on paying less for slower speeds. I want the slowest speeds at the cheapest cost that will not, or rarely affect my transfer speeds. Right now I think I'm paying for speeds I don't need. I figure I can always call them and raise it if it causes a problem. I generally have a lot of devices connected at the same time.

An observation here, as I have no add-on handgrips on my cameras. Like many photographers out there, I am right-handed. So if we are able to spin dials, turn knobs and reset buttons easier with our right dominant hands, why is that hand tied up grabbing the grip? Wouldn't it make sense for manufacturers to offer an add-on hand grip that attaches to the left side of the camera instead? You can now hold the camera with your left hand instead, and make all
your adjustments with your dominant right hand.
