All three had no OS. I put Windows 7 on all three. First two work and connect just fine. The third lights on the back as if it's connected. It says there's no driver, cannot connect. All three computers were the same (HD wiped to "DOD standards". I hadn't entered the COA on the computers, so the first two again, do connect. I don't know why the third wouldn't. Any ideas?
All three are i3's, if that matters
