Unable to connect to a mobile Hotspot

I have recently switched to ubuntu mate 16.10 from windows. I am using BlackBerry q10 as a source of mobile Hotspot but it’s not connecting. I have edited the connection to asci II password even then it’s not connecting. I tried connecting through my friends Hotspot it got connected. How do I solve the problem. Kindly help.

Even after typing the correct password it keeps popping up. Kindly help
