I bought an android box, and an android stick. like the fire stick. but android.
neither one of these will connect to my wifi. keeps saying, Cannot find. THOUGH IM CONNECTED WITH OTHER ITEMS. other boxes, laptops, cell, I use. is this locked in the hardware, from the seller? i did a test, and it did work, but ONLY ON AN OPEN WIFI, SOURCE.. so how do i fix it, to my address?
I don't need to reboot the modem, as its working fine. any other ideas, to find the mac address or something, that is preventing me from going online?


thanks
