Funny you mentioned that. I was at O'Hare airport and I looked at WiFi scanning and there was one hotspot named "covert 'something'", that was unlocked. I didn't try to connect to it.
Open hotspot gives a [slightly] faster connection than an encrypted one How to secure your open hotspot? By making sure nobody will want to connect to it
When I was in Ocean City, MD last week, I saw an open WiFi hotspot that was named CIA something. I didn't try connecting to it either. Sent from my SM-N900T using Tapatalk
