Interesting. I'm on AT&T Gigabit (Google Fiber competitor here in Austin) and I got 660Mbit on fast.com (Windows 10 desktop directly connected via Ethernet.) A MacBook Pro laptop with Wifi (802.11ac) connected a few rooms away shows 260Mbit.
Are you wireless or wired? If wired, that seems quite low.
Thanks for reporting. I'll test when I get home, but I'm also in Austin and have Gigapower. I was afraid that it would almost embarrassingly low, but your results gave me hope. I'm curious what the Google Fiber and Grande users here get.
I'm on Grande's gigabit and am getting ~180-200 Mbps over 802.11ac a couple rooms away. Sadly I don't have an ethernet dongle for my macbook pro to test a wired connection.
I'm also on AT&T Gigabit in Austin, wired, reporting only 490Mbps on fast.com. However, I can download from Steam at 950Mbps, and report similar speeds on other tests.
