    When sending data across a wireless network (from your PC to your Wireless Router to the destination PC across the globe), from your PC to your wireless network, is this considered a OSI Layer 2 or are we in the Physical layer already.

    I'm now self-studying for an CCNA, but the OSI concept still boggles my mind to some extend.

    Am I correct to say that by the time the data passes from your pc to the router, the data has already been encapsulated by a Frame (which in this case is 802.11x)?

    The link from your wireless NIC to the wireless bridge or router is OSI Layer 2 since the data payload is encapsulated in a 802.11x frame header.
