From 19999792d2889350611ba9e346d6a2924959dc2d Mon Sep 17 00:00:00 2001 From: Thadeu Lima de Souza Cascardo Date: Thu, 28 Oct 2010 20:01:00 -0200 Subject: [PATCH] rtl8187b: do not do per packet TX AGC Clearing the per packet TX AGC for the RTL8187B device appears to increase its overall TX power. This allows the device to associate and a connection to be established using APs a little further away. This is in accordance to what is done for RTL8187L devices and also what Realtek drivers do.
