I can not believe I only just now tried using CM's Wi-Fi Hotspot tethering. I tried that WiFiTether app that was big a few years ago, but that never worked. This one works flawlessly. And I'm getting the same speeds while browsing as my 20Mbps home internet. What the coon? It's 3G, too, not 4G. I guess I am all the way on the other side of the house, relative to the router, but still.... damn.
