I would like you guys ask a question related to the encryption.
In a wireless environment, if I am using HTTPS, the packets are encrypted with SSL/TLS, so why do I need wireless encryption?
Depends on what are you trying to hide.
Open/untrusted Wi-Fi risk is kind of blown out of proportion in the media as as long as you use TLS the data isn't sent/received unencrypted.
There could be a concern about metadata that can be intercepted, i.e. domains of the sites you visit which comprises your browsing history. Basically everything that is exchanged in a handshake preceding establishing a TLS channel.
The simple answer to that is not all websites use HTTPS. Furthermore not all data transfered across a network is Web traffic.
