I am running a Lenovo X1 Carbon. Model 20A8001WUS
Windows 7 64 bit
Intel 7260 wifi adapter with Bluetooth
The wifi driver version is 220.127.116.11
Bluetooth radio shows up as Intel wireless bluetooth 4.0 adapter Driver 17.0.1404.422
Lenovo seems to have really screwed up. Or Intel rather, with this 7260 wifi adapter. The speeds are abysmal and the drops are consistent enough for a non computer person to notice.
My issue however is regarding the bluetooth. Because in my experience bluetooth has issues like this that can usually be resolved.
ISSUE: Using a lenovo bluetooth laser mouse Model: MOBTC9LA
The device seems to work okay some of the time. Other times the mouse lags behind my hand and is slow. It is like, if I move my mouse a very small amount on the table, the mouse on the screen will not move at all at first, and then from no where the mouse will move much further than I would anticipate. So when its acting up, I might as well go back to the track pad. Thing is... it'll mess up for 30 seconds maybe and then go back to normal for five minutes. The interval is quite frustrating.
I am not gaming on the device. Although I suspect that the 7260 wifi adapter is the issue, I have seen similar bluetooth mice behavior on seperate systems. Sometimes a bluetooth stack upgrade or firmware on the mouse was required. But definitely not the first time I've seen a bluetooth mouse behave like this.
THANK YOU FOR YOUR HELP!
