Thank you Bruno, very interesting. I ran my 902 AP and 902 client about 10cm apart, at 2mW radio power. Had occassional stuttering on Qobuz streaming, but generally stable. Interesting that you had issues when there was more physical separation (it may not like renegotiating a link?)
I will download that image and try again at 100mbps. Thank you for the pointer to the latest version, and confirmation that it is working for you!
