From f9ff282d17ec652d63fa2404e47bb0e15ed95b69 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thibaut=20VAR=C3=88NE?= Date: Thu, 14 Apr 2022 12:39:04 +0200 Subject: mac80211 adjust QCA9561 PA bias MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ath9k is setting the TX PA DC bias level different on QCA9561 and QCA9565 although they have the same radio IP-core, which results in a very low output power and very low throughput as devices are further away from the AP (compared to other 2.4GHz APs.) In real life testing, without this patch the 2.4GHz throughput on Yuncore XD3200 is around 10Mbps sitting close to the AP, and close to theoretical maximum with the patch applied.
