Stick not connecting to internet via wifi

hi there. I’ve tried to connect the stick to my home wifi network and it does not work. I’ve tried on different wifi networks without success. Maybe is an encryption issue? My wifi uses WAP + WAP2 encryption combined.

message I get is “Establishing Connection This might take 2-3 minutes” and after that "Sandisk Wireless Stick could not connect to your preferred Wi-Fi network. Please check your Wi-Fi password r your network settings and try again. I’ve tried many times and checked the password but it does not work.

Thanks for your help
