Something else you could try is downgrading the firmware image. This can be done without patching the kernel by swapping out the firmware file: mv /etc/firmware/iwm-7265D-29 /etc/firmware/iwm-7265D-29.orig cp /etc/firmware/iwm-7265-17 /etc/firmware/iwm-7265D-29 The 7265-17 image was used in OpenBSD 6.9. The 7265D-29 image is used in OpenBSD 7.0. -current now defaults to the 7265-17 again, because we found out (a bit too late for the release) that the 7265D-29 firmware was causing issues.
