I went for a cheap Wi-Fi 6e router for now, as I found a very good deal on Woot. Not quite everything I need, but cheap enough to get me by for now.
I do plan on looking into the Banana Pi Wi-Fi 7 routers at some point, however, as that setup seems promising to me. But it was a difference of like $200 to go for the thing on Woot, hence this is where we’re at.
