But if you do more and more devices you find issues such as this won't take a space in the SSID or a password with uppercase letters.
You have a choice to make here. Call them on their lack of working with other systems or figuring it out and making it work.
I have a few tips in the CNET Networking Forum but while I hear you, I can only suggest what may make a device play along. If you feel this is a product defect, then return it and get stuff that works.
