Sometrhing seems fishy. I had 200+ mbps before a service outage in my area, now I'm stuck at 30 mbps or less no matter what plan I change to. The tech's say everything is fine. What do you do? My equipment is reset and still the same as before. ?????
Try calling in again and ask a rep to completely remove the modem from your account and to "re-provision" it from scratch. Also ask them to confirm that the provisioning and account data in their database is correct and complete and that the correct configuration / bootfile for your subscribed to speed tier is being pushed to the modem.
Good luck !
