Hi @Evan971
I personally have not connected to Wifi as a guest in the way that you described, but it makes sense to me that one can. My wifi network and password are saved on my listing. To do this you need to test your wifi speed - the speed and wifi details are then automatically added to your listing. Go to listings, amenities, wifi. You will see an "edit" option at the top of the amenities list. Click this and edit your wifi details and run the speed test.
HOWEVER, I recently upgraded my wifi and wanted to run the test again, but both the external testing service provider and Airbnb customer support confirmed to me that they are presently having problems with the function. So if you try it and it doesn't work right away, be patient (it has been broken for weeks, but one can see they are working in it).
I'm sure saving your details there and running the test will be necessary for you to get the auto connection option, but I'm not sure if the auto connect button will automatically appear for your guests in the guest view ....
