Well, it's arrived and working.
Max: Upstream rate = 25898 Kbps, Downstream rate = 90338 Kbps
Bearer: 0, Upstream rate = 19999 Kbps, Downstream rate = 79999 Kbps
That's the best max downstream I've seen for some time.
I'm getting something odd on the upstream when I run a speed test. It goes in distinct bursts.
Suggestions please.
