Hello @stylishhumdrum
Thank you for taking the time to post on the StarTech.com Community!
From what you have described, you are going through the correct steps for connecting the PM1115UW to a WiFi network.
I would suggest manually typing in the SSID rather than selecting it from the list at the bottom of the Wireless configuration page, as
If that does not resolve the issue, I see in your screenshot that the SSID you are trying to connect to has some asterisks in it, would you be able to try connecting it to a SSID that only has alphanumeric characters (0 to 9 or A to Z)?
Next I would recommend trying a different browser application, or even another computer if you have one available you could use.
I hope that this information is able to be of help to you and look forward to your reply!
