Invalid Password

I was getting a invalid password when I tried connecting so I tried changing password

To change password

1. Go to Mobile Hotspot page as instructed above
2. In options choose "configure"
3. Under "security" change the passsword

Connection Timeout

Now I was getting a new error "Connection timeout". Using the same "configure" option above I removed the password and specified "open" however was still getting the same error. I then went to "Allowed Devices" and specified my Macbook pro, Mac address and that solved the issue. Follow the below directions

1. Go to Mobile Hotspot page as instructed above
2. In options choose "Allowed Devices"
3. Follow these instructions to get your Macbook Pro MAC address. Choose "Wi-Fi" in connections
4. Specify the "mac address" in "Allowed Devices"
5. Turn off and turn on Mobile hotspot toggle.

Above solved my issue
