I just got the upgrade here, at least on the upload side. I currently have Blast and my download is still at 30mbps. Upload has doubled though to 10+ mbps. Modem (TM502G 3 in 1 Arris) has been powercycled. Any ideas?
Agreed. You need to get in touch with Comcast and have your modem swapped out for a Docsis 3 modem. Go here: »Comcast Direct
and talk to Comcast Steve, explain your situation, post your account info and contact info and he'll get you square.
