For the past several days, I haven't been able to connect to my Wi-Fi. When I try to connect, I get this 'Authentication required' but no password prompt comes up at all. I'm on Linux Mint. Can someone help?

Thanks. We'll let you know when a new response is added.

Have you tried rebooting your equipment? I have had similar issues with my network set up from Comcast. Was working fine one night , went to bed and next morning could connect but no internet access. Booted the modem and router and it all started working again.. Not sure why this happens but it was not the first and I guess it wont be the last.

    As you mentioned, no password prompts, probably, you installed with automatic login rather than requiring a password. Try this one, right click on nm applet > Edit connection > Wireless tab. Click on wireless hotspot you want to automatically connect to. Again click Edit button. Look for a check box which says Available to all users. Select the box & click Apply.

    Three information elements are needed before any useful answer is possible. First, what Linux Mint version are you running? Second, what desktop are you running? And third, what is "my Wi-Fi"? That is, what wireless router are you connecting to and what ISP provided it? (Or is it one that you bought to connect to an ISP-supplied router/modem?)

    Moreover you can try turning the wireless card off and then on again. Sometimes wireless card gets stuck that causes it won’t connect. Also check that you are using the correct type of wireless security.
