you need to post more information about your connection so stats from tplink
have you been having problems with router dropping connection?
any noise on quiet line test?
How about you posting some connection stats then rather than a screenshot of an estimate and a download speed reported by your router.
To ask about line stats and not show them does not beg an answer. Once you post them then someone will be able to advise.
What about quiet line test?
The stats are very brief - what about internet connection time not system uptime
