I'm on Arch linux, updated the kernel from 6.6.10 -> 6.7. Now it doesn't connect to my 5GHz wifi, to 2.4GHz it still connects. Also the earlier kernel version still works. Output from "sudo dmesg | grep -i wlp2s0": > [ 6.049600] iwlwifi 0000:02:00.0 wlp2s0: renamed from wlan0 > [ 131.095861] wlp2s0: AP is in CSA process, reject auth > [ 132.143170] wlp2s0: AP is in CSA process, reject auth > [ 133.599906] wlp2s0: AP is in CSA process, reject auth > [ 135.549325] wlp2s0: AP is in CSA process, reject auth > [ 145.510438] wlp2s0: AP is in CSA process, reject auth I notice that the commit c09c4f31998bac, which was added to kernel 6.7, introduced rejecting a connection with that error message "AP is in CSA process, reject auth". My guess is that commit is the cause of the regression.
