I recently got Infinity installed. At first I was getting about 55Mbps. However, on the second day the speed dropped to under 5Mbps. I called up and support had me plug and unplug the modem into the test socket and restart it many times. It turned out it was nothing to do with my line and there was an issue in my area that was fixed later that day.
However, my speed now seems to be stuck on just under 45Mbps. After reading about DLM I assume that the plugging and unplugging of the modem that support had me do has triggered DLM to reduce the line speed for stability. It's now been about 13 days since then (modem constantly connected) but the line speed hasn't increased.
I read that the "stable line speed is determined in the first 10 days". Willl DLM eventually put my speed back up to the 55Mbps it is capable of or will it be stuck at a low level now because these issues happened in the first 10 days when the stable speed was being determined?

just maintain connection 24/7 and DLM will bring speed back but may take a few weeks especially if you had many resets
