Hello, The AP is supposedly supporting 4 spatial steams with 4x4 MU-MIMO. But unfortunately, only 2 spatial streams are working. Therefore only one client can send and receive data at a time with...

@MR.S this is not 1Gbe but more like 850Mbit, which is exactly 80MHz 2x2 practical performance (with Intel AX chipset Im able to get up to 950MBit on 2x2). So no 4x4 in your case either. Is anyone...

@Tedd404 I did exactly that, 2x 1Gbe server and 2 devices that can handle 2x2 MIMO (Samsung S22 Ultra + iPad Pro M1). TPLink advertises 4x4 MU-MIMO, so BY DEFINITION (or to be more precise by...

@MR.S 1gig with 80MHz channel and two 2x2 devices or one device and 160Mhz? Or one device 4x4 (which is super rare) on 80mhz?

@MR.S indeed, I meant the 660HD and not the 653. Sorry for my mistake.

Hello, I dont think that problem is specific to this particular AP, it looks like every WiFi6 AP does have that problem. In theory a 4x4 MU-MIMO accesspoint should be able to deliever 4 spatial...
