Hi,

I bought this XPS 13 a month ago and the experience was bad.  After updating firmware and drivers almost everything is better but some issues with the sleep/wakeup and wifi signal are still presents.

My model is XPS 13 2-1  9365,   i7-7Y75 , 16GB LPDDR3 - 1866MHz,   InfinityEdge de 13.3" QHD+, WIndows 10 PRO 64-bits

sleep/wakeup: laptop is not going to sleep when It is connected to AC when I close or push the windows command. I see a blink, but the laptop awake in the login screen.  Sometime sleep fine but i need the push the power button for  long time for a hardreset.

Wifi:  Some times signal is poor, and ping to the router has high latency and package lost. It usually happens after waking up.   I fix it by turning off and on wifi.     

From other laptop and phone in the same location, the signal is optimal and latency is < 5.

I tried http://en.community.dell.com/support-forums/laptop/f/3518/t/19963459 unsuccessfully

Any ideas that can help me?
