Ohh, another finding: when disabling Bluetooth I’m getting from 3.2 Mbits/s to 78 Mbits/s (downloading).
If I re-enable bluetooth boom I’m back to ~3 Mbit/s.
If I disable bluetooth again, boom 74 Mbits/s.
Looks consistent and reproducible.
Looks related to MT7922 mediatek wifi card wifi/bluetooth issue
