Hi @kinhsman
Let's see what we can figure out. I have a speed comparison up on the Main Menu. Here is the direct link: https://github.com/morrownr/USB-WiFi/blob/main/home/Speed_Comparison_Test.m Note that the fastest adapter uses the same chipset that your Fenvi adapter uses. It has internal antennas which give a slight advantage to your Fenvi adapter. Let's see what we can do to optimize things.
I assume this is managed mode operation. Questions:
You can install
Run it: $ wavemon |

@morrownr
via iperf3:
5GHz
Channel 44, 80MHz
My AP is showing around 25%. Other devices can connect and get 700Mbps easily
802.11AX WiFi 6. Its a Meraki MR56
link quality: 97% (68/70)
One thing I notice is the CPU utilization is maxing out every time I run speed tests |

You signal level and link quality are excellent. This should allow for maximum speeds, give or take the congestion. About a month ago, I was helping another person. We did a lot of digging and finally discovered that the problem was the slow CPU in his old RasPi. I think the RasPi cpu had a single core running at 500 MHz. There was the problem. When you have a very old cpu, it may not have the power to push packets faster than what you are seeing. What hardware are you using? |

I am guessing it has something to do with the virtualization aspect of it, or maybe the USB passthough was not ideal for this type of adapter. |

Yeah. VMs can be a challenge. I don't run VMs so I won't be any help optimizing things. I have been told by others that this chipset and driver do work well in VMs. 681 Mbps is not bad at all. What you might do is start another issue with a title something like: Need help with mt7921au based adapter in a XXX VM And see if anyone can help. |

@morrownr Thank you! I will do that |

The performance of this USB dongle is acceptable, but it falls short of being ideal. I consistently achieve just a bit over 100Mbps for both upload and download speeds. I've tested it on both Windows and Linux (Debian and OpenWRT), and also both in Client mode and AP mode. I've come across instances where users report achieving much better results, around 300Mbps. If anyone has experience using this specific dongle, could you please share your setup details, including hardware, operating system, configurations, etc.? Your insights would be greatly appreciated. Thank you!
Edit: the speed tests were ran using iperf3, and openspeedtest server
