Just got Google Fiber a week or so ago. It's fucking fast, at least on my Wireless AC devices. Best I've gotten so far is on my work laptop:
Not too shabby for WiFi. My file server is also my media PC for my bedroom, so it can't be connected directly to the Google Fiber box which is on the ground floor. I tried TP Link's AV1200 powerline ethernet, connected directly to the wall sockets, and my upstairs PC says it's connected at 1 gigabit, however I'm only seeing speeds of 100mbit/sec up and down from that computer (using Cat 6 cable on both sides of the powerline adapter). I've never run wires through the house, and I'm a little afraid to try. Is there any Linux compatible Wireless AC adapter I should look at to get better speeds up there? Or does anyone have any good reading material online about running a Cat 6 cable around two floors? There is an ethernet adapter on the wall behind the media PC, but it's connected to another port that's on the same floor, that I think was utilized for the previous owners satellite dish. There are no other ethernet ports in the house.
Either get a wireless bridge, or run the cable. Wireless adapters on Linux generally suck, even if there's actually a driver for them.
