Just had a very quick resync, not sure if the router just lost PPPoE session or it was DLM's action. Lost about 1.5mbps download, gained 0.2mbps upload. SNRm is a bit higher, 6.1 dB now. IP hasn't changed either. Strange.

Anyone understands this log? Because I can't. Did it just drop PPPoE session? If so, do dropping PPPoE sessions affect speeds, SNRm etc?

Sorry, wrong time in router options, need to change it :P

That log needs to be read from the bottom upwards for the chronological order of events but needs to be read from the top downwards so that you don't start too far back in time!
 
What I see is that an xDSL resynchronisation event occurred. Then, as a result of the lower xDSL layer being taken down, so was the upper PPPoE layer.
