WiFi connection not working

Hi all,

I've freshly reinstalled parrot as I dual booted my computer to include an ubuntu partition for a daily driver. I was able to connect to the internet to run a parrot upgrade, but now when I boot up the computer, I cannot reach the internet. My external wifi card is detected through iwconfig and I can start to connect to my wifi signal, but it always fails.

​

I've tried the fix here but to no avail. Has anyone run into this problem? How did you get around it?
