I've been noticing more and more random disconnections at seemingly random times of the day. Sometimes it will happen when I'm on a Teams call during the day. Other times in the evening whilst watching Netflix.
It's been rock-solid in the past, but (anecdotally) after some "essential maintenance", I've started noticing these 5 minute or so dropouts.
I've seen a number of posts in here with "No Ranging Response received - T3 time-out" and the suggestion has been to create a new post - so here I am 🙂
Latest network logs below. I've only posted upstream, as that seems to have an error count in it. I'll post Downstream if someone asks, but it's a bit long.

Just a quick note to confirm you're satisfied with the response and efforts of the forum team? Remember if you ever need assistance in the future, our fantastic community and forum team are always willing to lend a hand.
When the technician's there, ask them about the "slope" on power levels. What I observe is that your power levels increase with frequency, when they should be flat or decreasing with frequency, and that's down to amplifier setup in a street cabinet somewhere.
Maybe simply fitting an attenuator or changing the tap you're on at the cabinet will resolve the issues you have, but they may not correct slope problems. If the changes they make work, then no worries, it's all technical mumbo jumbo you can ignore. If they make changes and the problems continue, you'll need another visit and my suspicion would be that the amplifier setup needs changing.
