swaywm, closing and opening of laptop lid connects to wrong wifi station

Hi, I have a wifi router and an extender/repeater. I connect to the extender's station to get the best signal, but when I close the lid on my laptop and then open it again, wifi resumes with a connection to my router's station, thereby losing about 30% signal strength so I need to manually disconnect from it and connect to the extender. I can't figure out where this happens. It is not in my sway config file and it doesn't seem to be in /etc/logind.conf either. Does anybody know how to configure this properly? Thanks, Morten
