Even with 802.11ad (that I don't have) there's a huge difference between having to plug in when you reach a "fast area" and not having to.
Going wired->wifi is like going desktop->laptop. I'll admit to being slow to go to both laptop and wifi years ago, but at least to me they're clearly superior.
service restart netif lagg0
service restart dhclient lagg0
Still I think it is awful.
I hear it is because the spectrum is jammed but I almost cannot believe it: I have a big garden and so have my neighbours.
What do you guys do to get fast, stable wireless?
The ubquiti has a spectrum survey mode that will tell you what sort of interference it sees on each channel. It takes 10's of minutes to run, and seems pretty thorough.
The real winning feature is that it is designed to be ceiling mounted, so I could place it in the center of my house, a few feet away from the nearest wall. There is also a mesh mode, where you buy more than one. If your house is big, and interference isn't the problem, that might help. I haven't tried it. They have newer / different models that do a better job of this than the UAP-Pro.
Later, I replaced my router with a pc engines apu2 running openbsd. Ubiquiti has a highly recommended cheap router (edgerouter lite) that works out of the box, if you aren't looking for a hobby project. People have gotten openbsd to run on it too.
