    When both Cellular Data (3G in my case) and Wireless are enabled and connected with full bars and full wifi strength, which interface does the device use to send/receive data? Is there a way (App) to tell which is being used and/or does it depend on the type of data (streaming netflix vs sending an email for example)?

    Thanks!


    Edit:
    The routing table shows 2 default routes which is what got me wondering in the first place:

    Internet:
    - destination: default
    * gateway: 10.10.1.1
    * netif: en0
    * flags: UGSc
    * refs: 320
    * use: 0
    * mtu: 1500
    * expire: -1
    - destination: default
    * gateway: 75.209.69.73
    * netif: pdp_ip0
    * flags: UGScI
    * refs: 25
    * use: 0
    * mtu: 1450
    * expire: -1


    First is my home network, second is my Cell Data.

    Does it ever switch to 4G if it senses a faster connection?

    I was watching a video and I had both 4G and WiFi enabled. I was in my own home, in range of my WiFi signal. I looked at the status bar and it said LTE instead of showing the WiFi logo.

    I went into settings and shut the Cell Data off and I received a warning message something to the effect of degraded video quality.

    I was always under the assumption that it would always be on WiFi unless WIFi was unavailable. This puzzled me and was a bit concerning, considering my 4G data is limited.

    I can tell you that it always shows the cellular connection when it's on instead of the wifi signal (why it doesn't show both the way my phone does, I don't know). Which connection it defaults to using, I don't know.
