+I have been discussing this with Larry Finger (one of the realtek main
+developers) in "wireless <linux-wireless at vger.kernel.org>" ML and this
+Larry Finger what he said:
+
+"That patch keeps your device from running forever at a maximum of 1
+Mbps by adjusting the initial gain of the RX amplifier. You may
+reverse it if you want so that you can detect more APs when you scan;
+however, most people prefer to get better performance from the device.
+That patch will not be reversed."
