Bluetooth Mouse lag

Recently bought the Surface Pro 128GB.

Having been annoyed by the temperament of the touchpad, I bought a Microsoft Bluetooth mouse.

What I've found is that, when copying data over a network, the bluetooth mouse begins to lag.

Using the touchpad/pen is unaffected.

Makes me wonder whether the Wireless NIC and Bluetooth Module are using the same bus and/or whether this is a known issue.

    Sometimes I also have the issue that the bluetooth mouse gets disconnected during high WLAN traffic and at the same moment the WLAN device shows a yellow callsign and doesn't work anymore.

    Because it's not possible to open the WLAN status/settings or the network control panel anymore I cannot say what's the reason for this.

    After a reboot it is working again, but surely still with a horrible mouse lag during downloads or local file transfers (e.g. from or to my Windows Home Server)

    I always have to use the touchpad instead the Bluetooth mouse because the mouse isn't useable anymore until the WLAN traffic is finished :-(

    btw: Windows 8.1 and the Surface Pro 2 Firmware is up-to-date and I tried 4 different n-WLAN Networks, it's always and everywhere the same disaster!

    Does anyone have an idea what I can do to solve this issue?

    If you use 5ghz wifi, you should not have any issues.  That fixed it 100% for me.  The issue is being caused by 2.4ghz wifi and bluetooth being on similar frequencies.

    I also noticed awful mouse lagging and audio glitches when streaming from my Google Music account to a set of bluetooth speakers. This started happening _after_ I let Windows update my SP2 to the latest firmware/drivers. Bummer!

    I also have the same issue with my Surface 2 Pro and a Logitech M555b Bluetooth-Mouse.

    It's not possible to change my WLAN to 5GHz because several devices in my network don't support 802.11a :-(

    So Microsoft, please help me!
