Title:
Can't enable WLAN on Dell platform when enabling control WLAN radio
then unplug LAN
Status in OEM Priority Project:
Invalid
Status in linux package in Ubuntu:
Invalid
Bug description:
There is a BIOS option to control WLAN radio on Dell laptop. When
plugging LAN cable, the WLAN radio is blocked, unplugging LAN cable
and the WLAN radio should be unblocked. Dell also has docking stations
like WD19 series that equipped with USB LAN.
The LAN chip on WD19 series is Realtek 8153 gigabit ethernet. The
issue is when turning on WLAN radio control and plugging the docking
station with LAN connection, the wireless network will be turned off.
While disconnecting LAN, the wireless network remains off.
The Realtek 8153 runtime power management is set to auto by TLP
package. If the power management is set to on, then this issue can't
be reproduced.
