I am running a version of SID (AntiLinux) with iwlwifi firmware version 20210315-2. In trying to set up the wifi, I discovered a problem with rfkill and the physical on/off wifi switch on this laptop. When the switch is turned on, rfkill reports that the wifi is HARDblocked. When the switch is turned off, rfkill reports that it is SOFTblocked. Have tried rfkill unblock wifi and rfkill unblock all to no avail.
I wonder whether others with disconnects have any similar problems? Steve Rinsler
