I recently moved on to a new connection using a Be LLU reseller. My sync speed was around ~15Mb.
I had some issues with my router where I had to reconnect several times within a short space of time, and now my sync speed does not get above ~12Mb. So I lowered the SNR margin on my router from 6db to 3db but the sync speed remains roughly the same (it can be different by a few kilobits).
Is it likely that my profile was capped due to the amount of restarts? Or could it be my router?
