Subject: [PATCH] hostapd: Fix WDS Repeater assoc fail on 6G with 160MHz
|
|
|
|
While trying to connect the STA with WDS AP, filling the chandef info
|
|
in the driver. In the Problematic case, receiving the EHT160 center
|
|
frequency is invalid. Due to this chandef validation getting fail and
|
|
returns a failure message.
|
|
|
|
[ 6340.667455] wlan1: authenticate with 00:03:7f:01:58:33
|
|
[ 6340.667502] wlan1: HE 6GHz operation resulted in invalid chandef: 6195 MHz/5/0 MHz/0 MHz
|
|
[ 6340.671605] wlan1: Rejecting non-HE 6/7 GHz connection
|
|
[ 6343.937592] wlan1: authenticate with 00:03:7f:01:58:33
|
|
|
|
From the analysis, didn't update the EHT160 center frequency information
|
|
in hostapd.
|
|
|
|
Fix it by updating the EHT160 center frequency information.
