Good day,
I have chose an QRT G-2SHPnD for replacement of my Metal 2SHPn…(I thank all people who helped me with Metal connections issues 
)
Right now I change default configuration of my QRT G-2SHPnD.
Below my exported configuration :

But I got authentication error when I am trying to connect my laptop in my house in spite of -81 dBm as signal strength (the antenna is installed outdoor at 13 meter from floor).
Someone can help me to better setup my product ?
