Does anyone own a Linksys WRT Access-Point with Marvell Chipset to test the WiFi downstream on his Mi9?

I recently noticed a MASSIVE drop in downstream speed (2.4 & 5 GHz) from over 100 MBit/s to max 20 MBit/s for 5 GHz and under 10 MBit/s for 2.4 GHz. Upstream otherwise seems to be unaffected. I guess the downstream dropped since Android 10 Update, but I'm not sure.

The problem does only exist on my Marvell based Linksys WRT AP, another TP-LINK Atheros based AP delivers full speed on my Mi9. Other devices connected to my Linksys AP also deliver full speed, so it seems to be a speficifc problem between Mi9 <-> Marvell WiFi and only affects the downstream.

Can anyone proofcheck?

Just for the Records: Newest Weekly on Mi9 and newest OpenWRT Firmware on both AP's. Just checked with my Wife's Mi9SE and Android 9... Full speed on downstream.
