Can I ask what you are going to use the elusive 4.11Mbps for when you have 73.29Mbps to play with, which most people can only dream of?
Firstly I'm trying to figure out why my hardware reset itself and all the settings which were brilliant since installation. Then how to get the profile raised again to the installation level?
It could have reset itself due to either a power outage or a software update.
I didn't know that resetting both router and modem would have a detrimental affect on trying to solve things. Why would the technical help desk put you through this if it would have no benefit to raising your profile? Surely, they should've said leave everything alone and it will raise itself in a while
It is a standard starting point for the helpdesk to have you reset everything back to factory settings. This is to try and rule out any misconfigurations. As you have already been advised, the best thing is to leave the modem switched on 24/7 and the profile should slowly increase. This can take a number of weeks. As you are already on such a high profile it would tend to indicate there are no problems with your line. If there were DLM would reduce the profile.
