Hello, you could try to adjust the centre frequency for the 2.4Ghz wlan channel, but first you need to check what are the allowed channels for the 2.4Ghz band in your country. Don't forget to adjust the frequency and also the scan list for both sides of the wireless link. Also take in consideration your channel width and if you are using extension channels, then adjust the extension channel if it should be located below or above the control (main) channel.
Edit: Did not notice the model, these indeed are dual chain, so 5ghz only.
