Hello,
i have the same problem, with Extreme 3.0 32GB. My notebook is Acer Aspire S3-391 (like Macbook Air 13"), there is only two USB 3.0 ports and built in Wifi. I am using Microsoft wireless mouse in first USB port. After inserting Extreme into second USB is wifi disconnected and wifi mouse is disconnected too. But USB drive is working fine.
I tried this problem with other USB flashes and with USB external HDD drives. With ordinary USB flash is it ok, but with USB 3.0 or with external HDD it will disable wifi too.
So my conclusion is propably problem with power in notebook, maybe is power in USB 3.0 mode bigger, and there is some conjuction in circuit between internal wifi and USB ports.
On other bigger notebooks (lenovo, Macbook Pro 15, MSI GS70 17") is all ok, no problems.
