Issues with MLO enabled Wifi 7 Download Speed

davidfi01

Attached find an image (speedtest at router.png) of a speedtest run taken at the router. At the router, I am consistently seeing upload and download speeds of >1Gb/sec.

The router is hardwired to a NWA130BE via a switch with a 2.5GB port.

Attached (mlo setup.png) is the Nebula config for the access point. NOTE that I have configured a separate VLAN for WIFI7 and only connect Wifi7 devices to it.

When I run speedtest at the PC, I am regularly getting only 0.5 GB download speeds while I get 1 GB upload speeds.

Why can't I achieve 1 GB download speeds?

NOTE: I also connected the PC to the ap via cable at 2.5 GB (see Hardwire config.png). Using a cable to the ap regularly shows up and down speeds >1GB/sec (see Hardwire to ap results.png).

What changes to my config do I need to make?

The wifi adapter is an Intel Wifi 7 BE200

Thanks,

D

bad Antenna ?

have you checked for derive updates?

Windows on 24H2? Intel driver update? NWA on 7.10? Check connection is really on MLO (live view clients in Nebula cloud).

I think there is something messed up with Intel BE200 chip. I have one, as well as a Qualcomm FastConnect 7800 and a Realtek (don't remember the version). The Intel and Realtek perform about the same. The Qualcomm is pretty fast. Like Chris888 said, check to see if its using MLO, the Realtek is supposed to support it but does not (the Unspecified manufacturer), The Intel and Qualcomm do:

Here is my Intel speed test:
