From: Larry Finger <Larry.Finger@xxxxxxxxxxxx> Date: Tue, 5 Nov 2013 15:15:29 -0600 Subject: [PATCH] rtlwifi: rtl8192cu: Fix incorrect signal strength for unassociated AP 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.
