Subject: rtlwifi: rtl8192cu: Fix incorrect signal strength for unassociated AP
From: Larry Finger <Larry.Finger@xxxxxxxxxxxx>
commit 78dbfecb95be4635b995af3bd29fa10013409fcd upstream.
The routine that processes received frames was returning the RSSI value for the
signal strength; however, that value is available only for associated APs. As
a result, the strength was the absurd value of 10 dBm. As a result, scans
return incorrect values for the strength, which causes unwanted attempts to roam.
