    Unhappy Bluetooth and Wifi don't work together

    I'm loving my TF300 with the keyboard dock, but this one may be a deal killer for me. Any time I try to use Bluetooth and Wifi at the same time something doesn't work. If I'm' trying to browse the web using my Bluetooth mouse, the mouse isn't responsive while the page is loading. If I'm listening to music on my Bluetooth headphones, web pages take FOREVER to load. And forget about trying to watch YouTube videos whith Bluetooth headphones or speakers.

    A network speed test shows 3.5 mb/sec down without bluetooth running and 120 k/sec while listening to music on my bluetooth headphones.

    With a little searching I found this is a known issue on the TF201, but you'd think they would have it fixed for the TF300 since they knew about it before.

    Anyone out there able to use Bluetooth and Wifi at the same time? Any hope this can be fixed?

    Channels operating at 40 MHz are another feature incorporated into 802.11n; this doubles the channel width from 20 MHz in previous 802.11 PHYs to transmit data, and provides twice the PHY data rate available over a single 20 MHz channel. It can be enabled in the 5 GHz mode, or within the 2.4 GHz if there is knowledge that it will not interfere with any other 802.11 or non-802.11 (such as Bluetooth) system using the same frequencies.

    might be your wifi interfering with your bluetooth. try changing the various modes in your router.

    I had a couple of Primes. It loses about 90% of wifi speed when bluetooth is running. That's horrible if you are starting with 3.5 mbs. I posted this over on xda prime forum:

    "I don't know if the new tf300 is using the same chip but if you look at the FCC filing for the 300, it looks like Asus is giving up on simultaneous wifi and BT. Look at the second footnote.

    Product Name ASUS Transformer Pad
    Trade Name ASUS
    Model No. TF300T
    FCC ID MSQTF300TNH615
    TX Frequency 2412MHz~2462MHz
    Type of Modulation DSSS/OFDM
    Antenna Type PCB
    Device Category Portable
    RF Exposure Environment Uncontrolled
    Max. Output Power
    (Conducted)
    802.11b: 16.84 dBm
    802.11g: 11.29 dBm
    802.11n: 9.66 dBm
    * Note : Per FCC KDB 616217 D01,
    (1) The output power of BT is less than 10mW ,so SAR not required .
    (2) BT & WLAN can’t work simultaneously, thus simultaneous mode is no need.

    Someone who has a bluetooth headset should run the speedtest.net app with and withour bluetooth streaming and report results. It would be interesting to see.

    I think people don't get it. wifi can interfere with bluetooth if they're operating on/near the same channels. bluetooth and wifi at 2.4ghz can interfere with each other....even your neighbors wifi can cause you issues.

    Thanks for all the replies, they've turned out to be quite helpful. I took the advice of those who suggested changing settings in my router, and I have found they were set poorly. While the TF300 does seem to be more sensative to interference than my HTC EVO, I no longer consider this a defect. My router was set to channel 11, which you can see in the results below, was the worst of the settings (by far) for my circumstances. I've change the channel to 7 and things are much happier. Thanks for all the input.
