No, I haven't. I may have had the switch before the first WRT3200. If not I had something very much like it that it replaced.
I'm old-school. I still consider wireless for situations where you can't run Ethernet. Yeah, I know, it's a lot better now than it was 20 or so years ago. Speed tests on my iPad over WiFi match those of my wired desktops. But old habits die hard.
I'm only using eight of the ports. I just like higher-end gear. I live in the boonies, and the nearest place I can get this sort of stuff same-day is a Micro Center two and a half hours away. So I aim for hardware that will last.
I also have some less-impressive spares that I could swap in in a pinch for basic functionality until a convenient time to make the trip. I probably would give CAKE SQM a try at that point to see if I could get away with an unmanaged switch.
I used to use Roku until a firmware update bricked all my boxes and Roku wouldn't make it right. They were old, though; so I went to Wally World and bought two new ones. I only set one up, and sure enough, the update bricked it. I brought them back to Walmart for a refund.
Being a veteran, I get 10 percent off on Apple stuff; so I decided to give their AppleTV 4K a shot. As is typical with Apple products, it cheerfully set itself up when it found my iPhone (or vice-versa). It's been working flawlessly ever since. It just works.
In the interest of thread drift, my almost 84-year-old father broke his hip a month or so ago. My sibs and I decided that despite his past stubborn refusals, we were getting him a phone. One sib donated a used iPhone XR, and I updated it and got him on an annual AT&T plan.
I had the phone set up except for the voice training when I handed it to Dad. I also gave him a script to get further acquainted with Siri. Now they're best friends. Mom says he talks to Siri all day, mainly about baseball. He makes FaceTime calls, looks up sports scores, and is even letting Siri manage his calendar now. They're BFF's.
So yeah, I like Apple stuff. But some of the AppleTV apps consume huge amounts of bandwidth. So I throttle it with the switch. I mainly watch the news anyway, so it doesn't really make a noticeable difference.
