From 317750d0973919ed0dc34ca7a2c0d3d02db570b1 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 22 Feb 2014 14:52:48 +0100 Subject: [PATCH] ath9k: do not set half/quarter channel flags in AR_PHY_MODE 5/10 MHz channel bandwidth is configured via the PLL clock, instead of the AR_PHY_MODE register. Using that register is AR93xx specific, and makes the mode incompatible with earlier chipsets. In some early versions, these flags were apparently applied at the wrong point in time and thus did not cause connectivity issues, however now they are causing problems, as pointed out in this OpenWrt ticket: https://dev.openwrt.org/ticket/14916 Signed-off-by: Felix Fietkau Signed-off-by: John W.
