Hi there,
I had some issues with the WiFi setup in my office. The space seems to fairly crowded but I only need to use WiFi in a single room, with a distance of 4 meters and with clear line of sight. My setup is to broadcast multiple SSIDs, that are all connected to a different VLAN. I also have about 30 clients, especially on the 2.4GHz band with about 20 IoT devices.

I first used the hAP ax2, this had some severe issues with WiFi speeds, spontaneous disconnects and so on. Also, my configuration was incorrect, not setting the dBs correct for gain. I learned a lot from the wifi video on mikrotik from Ron Touw on the mikrotik youtube channel: https://www.youtube.com/watch?v=JRbAqie1_AM. My key takeaways are:

• Its not that simple

• I should account for the dBs of adapters and antennas and I can improve quality of signal by possibly reducing dBs even further. There is a clear difference between signal strength and quality.

• I should disable DFS channels for 5 GHz if I dont need them and disable B Chipsets on 2.4 GHz.

• I should play with the width of channels more, to see what works. Larger width can mean more interference and worse performance.

Out of frustration, I got the Chateau Pro ax, which supports mimo 4x4. I was hoping that this would reduce spontaneous disconnects with the many clients I have, and it did! After settings up the configuration, I was waaaaay better performance too, so things were looking up too. If I check my connection with `wavemon` (a linux CLI tool) I can see that the connection for

• 2.4 GHz has about an 99% Link Quality and -42 dBm; rx rate: 309.7 Mbit/s 40MHz, tx rate: 206.5 Mbit/s 40MHz

• 5 GHz hat about a 69% Link Quality with -62 dBm; rx rate: 600.4 Mbit/s 80MHz, tx rate: 720.6 Mbit/s 80MHz

In practice, when I run an internet speed test I get about 250 Mbits in 2.4 GHz and 450 Mbits on 5 GHz. On the 5GHz band running iPerf I also get the result of bandwidth of 450 Mbits/sec.

My core question is: is this more or less the maximum I can get out of this WiFi adapter, or is there more performance lying on the table? If there is more to be gained, how do I get it? Any pointers would be welcome here. The performance is already a lot better than what I was getting with the hAP ax2. On the other hand, I was seeing in reviews that other people can get 850 Mbits out of the hAP ax2 via wifi, which is way more than what I have now with the Chateau Pro ax.

In other words, what's your experience like?
