I had the craziest dream. TWC finally completed D3 upgrades near Warren Ohio and I finally, after over a year of calling, got my upgrade. I hooked up my new SB6580 and made sure everything was working right. Then I went to post it on DSLReports and the site had kerploded massively.
Seriously, what are the odds? Anyway, here is the results on Extreme 30/5. I usually get near or exceed 30/5 even during peak hours. I didn't at first; it took a few days before I had more than 1 downstream channel, after a few days they bonded 4 channels and it's been perfect ever since.
