Subject: [PATCH 2/4] rtlwifi: rtl8723ae: Don't use dm.undec_sm_pwdb for input
Date: Fri, 4 Jan 2019 12:48:43 +0000 [thread overview]
Message-ID: <DB7PR07MB5353656A6EDA15D210CE098FE48E0@DB7PR07MB5353.eurprd07.prod.outlook.com> (raw)
gain control when no beacon was received in the connected state.
This avoids sporadic "Connection to AP ... lost" errors.
Signed-off-by: Bernd Edlinger <bernd.edlinger@hotmail.de>
