Thank you so much for your prompt reply. I live in a condo where all tenants share the wifi, which is provided by the management, with each other, and only management has the access to the router, not the tenants. So, I put all the login information in the /etc/wpa_supplicant/wpa_supplicant.conf. I could be wrong, but since the wpa_supplicant.conf has all my login information, it should automatically log into the network once it is boot up, right? Do I need to to have access to the router in order for this to work? Once again, thank you so much for your help.
