Hi Lantis,
On 1.15.x/OpenWrt 24.10 firmware I find something strange with 5GHz Wi-Fi. Below is a partial setting in my /etc/config/wireless.
Code: Select all
config wifi-device 'radio0'
option type 'mac80211'
option path 'soc/soc:pcie/pci0000:00/0000:00:01.0/0000:01:00.0'
option band '5g'
option channel '149'
option htmode 'VHT80'
option country 'US'
As you see the wireless channel is set to 149. After rebooting, it happens that clients connect to WRT3200ACM through channel 153 not 149. This can be identified by a Windows client. Any comments? Thanks.
Windows is potentially misreporting the channel. Do other clients see the same?
When you choose 149 and 80MHz, you are bonding 4x20MHz channels 149, 153, 157, 161.
The primary channel (where main signalling occurs) should be on 149 (as nominated in the GUI). This should be what a client reports as the channel.
Some clients will read this as “155” which is a fake channel at the centre of the 80MHz width.
So either Windows has it wrong, is choosing to report the beginning of the centre channel, OR, your device has switched its primary to 153 for some reason.
Checking the logs on your device, and the output of “iwinfo” can verify on your end.
