Trying to connect to my PC wirelessly.

the default name of the Wireless stick’s wifi network will be SanDisk Connect ###### (the ##### is the unique identifier) If you are in your house it should be the only sandisk connect wireless name so it shouldbe easy to find. You will need to be connected to the wireless stick network only without internet connection in order for this to work. 

Here is some info that may help
