How long for DLM to increase speeds?
Seems to be perfect. Have issues with Neflix on an Amazon Fire TV but that's nothing to do with you guys 
DSLstats is really good at letting you see what's going off on your line with the HG612 modem 
Cannot see your initial stats but it looks like G.INP has kicked in and now dropped you on to a 5dB profile. All good 
Waiting definitely seems the key with DLM, took mine 6 months to do something like this!
