won't ask to join networks

[confidentialfool]

hello all-
my wireless is set to "ask to join wireless networks", yet it never has asked me before. when i join a network manually, for example my home router wireless for which i entered a password successfully, it shows a check next to the name and full wifi service. however, when i go back to safari the wifi icon doesn't even show up on the top bar. it only and always uses edge. suggestions? explainations?

thanks,
lauren
