I know about this issue for 3 years I own Deco mesh, so we can safely assume it is known issue. It survived through multiple interations of Deco firmware upgrades and major Deco app rewrite - it would be safe to assume this issue is of very low priority for TP-Link Deco software development team.

My recommendation: just ignore it.

My other recommendation: check traffic stats per Deco node instead of for each of devices connected to it, totals per Deco node seem to better reflect reality.

Thank you for your reply!

That is pretty poor design from TP-Link as this is so elementary.

I also observed today while the individual mesh nodes traffic do fluctuate around 10-250 KBit/s I found the issue is the same.

3 clients streaming 4K content and the node under observation never exceeds ~300 KBit/s which again is impossible with 3 concurrent streams.

Will this ever be fixed? Becuase this doesn't look good on TP-Link at all.

Cheers
