Subject: [PATCH rtw-next 3/5] wifi: rtl8xxxu: Fix the 40 MHz subchannel for RTL8192EU, RTL8723BU
Date: Sun, 16 Nov 2025 22:29:20 +0200 [thread overview]
Message-ID: <150bf88d-9e12-412b-abc6-5313cb4d62d6@gmail.com> (raw)
In-Reply-To: <b735b9c6-f17f-405a-8972-a7c98f3c89e2@gmail.com>
rtl8xxxu_gen2_config_channel() was missing the subchannel setting.
This function is used by RTL8192EU and RTL8723BU.
This change seems to make no difference in my testing on channel 13
with either chip.
