Can anyone recommend any wifi testing tools for ChromeOS or Android?

 

My wifi is fine, I'm just playing around to learn something new. I have a new Pixelbook and Cambium e400 WAPs. Both have 5GHz 2x2 AC.

 

When I set the channel width to 40MHz, I connect (theoretically I think) at 400 Mbps. Output of network_diag --wifi includes:

 

 tx bitrate: 400.0 MBit/s VHT-MCS 9 40MHz short GI VHT-NSS 2
rx bitrate: 400.0 MBit/s VHT-MCS 9 40MHz short GI VHT-NSS 2

 

When I set the channel width to 80MHz, I get the theoretical max of 867 Mbps. network_diag --wifi again:

 

 tx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2
rx bitrate: 866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2

 

I appreciate that the wider channel width is more likely to be subject to interference and therefore have real-world poorer performance. I'm keen on figuring out whether that is the case for me and the wifi environment surrounding my house.

 

The Cambium APs do have a wifiperf endpoint built in, and Cambium suggests testing with Ruckus' Speedflex app. I can get that to work on my phone but not on my Chromebook so suspect it's not fully compatible. Any other suggested testing solutions?

 

Again, emphasising that my wifi is actually fine right now, real-world constraints will be upstream etc., I'd just like to learn more about this stuff because, well, geek.
