| Subject: rtlwifi: rtl8192de: Fix incorrect signal strength for unassociated AP |
| |
| commit 3545f3d5f4af715c914394123ce7725a9cf0a1c4 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. |
