Intel Compute Stick Stck1A8Lfc Wireless/Bluetooth Driver

hi i am new to Ubuntu , i am using the compute stick with its supported OS Ubuntu 14.04 , but i needed to clean the 8 gb embedded flash drive . so now i cant connect to the net. when i type to terminal about wireless. it says ''no file extensions'' i dont know what to do. i found some packages for drivers. but dont know how to install them . just stuck.

UPDATE: I have managed to install 14.04 and on external drive 16.04 and on 16 changed the kernel version to 4.12.0 then used the wi-fi and bluetooth package in the link. then started the network again it is DONE THANKFULLY!!!
