[-- Attachment #1 --] Hi, Today I upgraded from releng/13.0 to stable/13 but found my iwn device could no longer scan for access points. I rolled back to releng/13.0 and everything was fine again. No config changes were made during the upgrade or rollback process. /var/log/messages contained messages such as the one below with each scan attempt: Feb 16 16:12:33 mobile1 wpa_supplicant[385]: wlan0: CTRL-EVENT-SCAN-FAILED ret=-1 retry=1 I didn't see any other errors except ACPI stuff which looked normal to me for this machine. For reference, here is the pciconf output for my device: iwn0@pci0:2:0:0: class=0x028000 rev=0x35 hdr=0x00 vendor=0x8086 device=0x 422b subvendor=0x8086 subdevice=0x1121 vendor = 'Intel Corporation' device = 'Centrino Ultimate-N 6300' class = network Is it possible that work being done for iwlwifi could affect scanning with iwn and other drivers? On a separate subject, I had tested iwlwifi on a separate machine with stable/13 and an AX201 and it was quite stable (though slow as has been reported by others). Keep up the great work! Thanks, John [-- Attachment #2 --] <div dir="ltr"><div>Hi,</div><div><br></div><div>Today I upgraded from releng/13.0 to stable/13 but found my iwn device could no longer scan for access points.
