works fine on iwm0 at pci2 dev 0 function 0 "Intel AC 7265" rev 0x59, msi iwm0: hw rev 0x210, fw ver 17.3216344376.0 tcpbench from this iwm0 client to an em0 server over an 'J9650A HP E-MSM430 Wireless Access Point' configured as bridge went from bandwidth min/avg/max/std-dev = 20.039/28.960/31.578/2.921 Mbps to 670720840 bytes sent over 59.047 seconds bandwidth min/avg/max/std-dev = 57.874/90.801/105.435/11.927 Mbps in the other direction (eg tcpbench -s on iwm0) i get this on a first 20s session: bandwidth min/avg/max/std-dev = 38.328/49.347/54.263/3.980 Mbps then a second 20s session gives: bandwidth min/avg/max/std-dev = 31.687/82.597/97.757/17.791 Mbps a third: bandwidth min/avg/max/std-dev = 60.839/88.534/101.340/10.263 Mbps so that looks pretty stable & solid, great stuff ! Thanks ! Landry
