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!

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.

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!
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.

as already stated before, even though this may fix the issue, users don't always have 5GHz capable routers nor connectable devices. I don't, so this is no option for me.
