Verizon Fiber.
My connection is supposedly symmetrical. This is motivating me to check this a few more times and maybe mention that my U/L is 1/8th of D/L speed...
Either way, I am thrilled with Verizon (for once) for putting this screamer in my home... The only thing killing me is their supplied router, which was set to update firmware silently. The last update killed off every Mac in the house for wireless. I had to reinstall the old version for now.
