wireless networking - Turning on Bluetooth disables wifi on Yoga 2

    I have a Lenovo Yoga 2. The moment that I turn on bluetooth, the wifi drops out - I lose connection, and connecting again shows "connection failed". If I turn the bluetooth off, wifi can reestablish fine. I've tried lots of different combinations of drivers for both the wifi and the bluetooth, but no combination has has changed this behavior yet. I've read some speculation that the cards have insufficient shielding, but that seems like kind of a large flaw to ship with.

    I've tried with a Carbon X1, a Yoga 2 Pro, and a Yoga 2 all next to each other on the desk while running InSSIDer. The X1 and the Y2P don't lose wifi connection when the bluetooth turns on, but the Y2 does immediately. The Y2P and the Y2 are running the same drivers for bluetooth and wifi, and appear to have the same wireless card internally.

    During the failure state, InSSIDer still sees signal strength for my network, but I cannot connect to it.

    stats:

    • the card that comes in the laptop is an Intel Wireless-N 7260
    • Intel Bluetooth driver is at 17.0.1401.422
    • Intel Wireless driver is at 17.0.2.5
    • Windows 8.1 x64
    • Home wifi is a Medialink MWN-WAPR150N

    Wikipedia has good articles on both 802.11 WiFi technologies and Bluetooth technologies.

    Wikipedias quick summary of the differences:

    Bluetooth and Wi-Fi have many applications in today's offices, homes, and on the move: setting up networks, printing, or transferring presentations and files from PDAs to computers. Both are versions of unlicensed wireless technology. Wi-Fi is intended for resident equipment and its applications. The category of applications is outlined as WLAN, the wireless local area networks. Wi-Fi is intended as a replacement for cabling for general local area network access in work areas. Bluetooth is intended for non resident equipment and its applications. The category of applications is outlined as the wireless personal area network (WPAN). Bluetooth is a replacement for cabling in a variety of personally carried applications in any ambience.

    So basicly, 802.11 is an addition to the networking and connecting of computers & smartphones supporting high-bandwidth, and covers large areas.

    Bluetooth is a ad-hoc wireless technology which works at low distances, making it perfect for file tansfersing and remote-control hardware.

    Wireless is a general term talking about any type of communication that involves communication without wires. Bluetooth is a specific wireless technology.

    Bluetooth is used for low bandwidth, short range wireless (usually only a few feet) communication typically between devices such as phones, computers, GPSs, etc.

    Examples of other wireless technologies include:

    • 802.11 (Wifi) - Used for traditional IP data, such as internet traffic, over short distances
    • WiMax - Broadband like IP data.
    • GSM - Used in cell phones

    When most people talk about "wireless" they are probably talking about a particular wireless protocol called IEEE802.11 which is used for wireless networks. Bluetooth however is an alternative wireless protocol and is typically used for short range 1-1 communication and was originally designed as a wireless replacement for RS232 serial cables.
