WiFi frequency channel change
Interface has to be in monitor mode. First bring it down with ifconfig wlo1 down Then change it with iwconfig wlo1 mode monitor Bring it back up ifconfig wlo1 up Change channel iwconfig wlo1 channel 40
Sometimes changing channel will be on auto mode therefore these command won't helpful because it changes to 5GHz or 2.4GHz automatically
iwlist channel shows which channel to select.
iwconfig wlp2so freq 2.4G
iwconfig wlp2so channel 44
You need to make changes on wireless router and set manual channel select. See the image below
