[Bug 1528009] [NEW] hard blocked rfkill status of second WiFi adapter is incorrectly handled
Public bug reported:
Toshiba Satellite C50-B-19U laptop contains a WiFi adapter handled by
ath9k kernel driver. This WiFi adapter got disabled somehow and "rfkill
list" reports that it is in "Hard blocked: yes" state. (Pressing the
WiFi button only changes the "Soft blocked" state.)
I tried to quickly work around this problem by plugging a second WiFi
adapter to an USB port. This second WiFi adapter is reconginsed and
"rfkill list" reports to that adapter that it is "Hard blocked: no"
state. However nm-applet shows for both adapter "Wi-Fi is disabled by
hardware switch". The same thing happens with the "nmcli radio" output.
I have done some investigation and found that:
- if only one WiFi adapter is in the system and it is "Hard blocked: yes" state then "nmcli radio" reports WIFI-HW disabled, that's OK
- if two WiFi adapters are present in the system and one of them is "Hard blocked: yes" state and the other is "Hard blocked: no" state then "nmcli radio" reports WIFI-HW disabled. Expected would be that only the had blocked WiFi adapter is disabled, the other one which is "Hard blocked: no" shall still work. nm-applet lists the two adapter separately anyway but both seems to reported as "Wi-Fi is disabled by hardware switch" which is not the correct situation in the system
- if the first WiFi adapter's kernel driver is unloaded then the second WiFi adapter remains in the system only with "Hard blocked: no" state and that adapter starts to work. "nmcli radio" reports that WIFI-HW is enabled.
