Running a Surf Soho with firmware 6.1.0 build 1419. Current options for Wi-Fi encryption are limited to WEP and a combination of WPA and WPA2.
My request is to offer WPA2 as its own choice (that is, to block WPA).
WPA2 is more secure than WPA and almost every Wi-Fi device supports WPA2 at this point. Most Wi-Fi enabled routers already have a WPA2 only option.
