I am doing some research on WiFi for my school and one question I want to answer is what encryption is the most used. One day it was of course WEP and now it is WPA2 I assume, but it would be great if someone knows a recent source with percentages.

    WEP has been deprecated and IIRC WPA is maintained only for compatibility reasons. I don't think you can get accurate enough statistics as most wireless networks are personal. I'm voting to close this post as the answers would be only opinion based – Mr. E Dec 27 '16 at 17:22

    Don't close the question. I've provided actual survey information below; and people may find it enlightening (and disturbing) to know that almost 10% of networks still use WEP! – John Deters Dec 27 '16 at 19:25
  • @JohnDeters A correct answer will change in the future so it's not a good fit for the site. – Arminius Dec 27 '16 at 22:37
  • @Arminius How can I edit my question so that it fits in this community? Or is there just no way? – Ruben Dec 28 '16 at 10:18
  • @ Arminius In my eyes the WiGLE.net source seems prett good? It also updates over time. (sorry for the two comments, I can not edit) – Ruben Dec 28 '16 at 10:19

WiGLE.net is a site where people upload information about WiFi access points they've discovered. It's not complete, but it's a very large survey that should at least show you the trends you are interested in. This table is from their current stats page:

Wireless Encryption

WPA2: 171,834,316 (56.37%)
WPA: 23,980,785 (7.87%)
WEP: 29,492,258 (9.68%)
????: 60,103,751 (19.72%)
None: 19,818,038 (6.50%)
  • I'm interested in the fact that 6% use nothing .... – schroeder Dec 27 '16 at 19:45
  • @schroeder I bet most of them offer very limited internet access (just DNS) and have a captive portal to pay up. – Navin Dec 27 '16 at 21:13

    @schroeder, the majority of unencrypted networks in my area are either "xfinitywifi" or the automatic "guest" network built in to a bunch of routers. In either case, it's a captive-portal system. – Mark Dec 27 '16 at 21:35
  • @Mark ah yes, hadn't thought of captive portals. – schroeder Dec 27 '16 at 21:44
  • If you look at the map, there seem to be lots of samples from the sea, and some of them track a path. Are ship-mounted access points being over-represented in the resulting statistics? And what about home access points in predominantly residential areas, worldwide? I really am not sure how much faith to put into these data. – Lightness Races with Monica Dec 27 '16 at 22:20
