I've currently had Charter 100/10 speeds since January. Just recently they've upgraded speeds to 200/12. The speeds were banging right out the gate for about a month(100/10 service). Since then, (According to speedtest.net) I cant get above 70 for a download from any server. * All tests were conducted wired from desktop to arris tm1602 modem. *
I've tried other tests that show promise, but maybe I'm old and not understanding.
And then these show extreme low speeds.
