Satellite P50t-B-104: - WiFi doesen't work well

Question

My new Satellite P50T-B-104 has an Intel dual band wireless-ac 3160 adapter.
Wi-Fi and also Bluetooth is supported by this adapter.
Bluetooth is running well.
On the Wi-Fi side there is no network in the connection list, although in our neighbourhood area there are a lot of private networks.
So first I updated the adapter (now driver 17.0.5.8 from the Intel homepage) but nothing change.
Then I tested it with my smartphone as a mobile Wi-Fi-Hotspot. I only receive a Wi-Fi signal, if the Wi-Fi sender is direct (max 10 cm) near the notebook.
It`s more a NFC than a Wi-Fi functionality.
If I placed the Wi-Fi-Router on the keyboard of the notebook Wi-Fi is running well.
I suppose the Wi-Fi antenna has a failure or does a controller exist to regulate the Wi-Fi sensitivity?

Hi xaver,
there is no difference with or without AC power suply. There is no problem to connect to my router, the problem is the poor possible distance between notebook and my WLAN router.
When you start your WiFi functionality of your notebook for the first time your WiFi adapter present a list with all the possible WLAN networks in your neighbourhood. In my case normaly there must be six oder seven WLAN networks and one of this WLAN networks is my network.
I also tested WLAN functionality with a USB WLAN stick. The stick was automaticly installed and recognize 6 different networks. The integrated WLAN adapter only one, my router and only by a distance of 10cm or closer.
Now I placed the notebook in a distance of 1 meter from my WLAN router. The integrated WLAN adapter doesn't receive any network, the list of the possible WLAN networks for the integrated WLAN adapter is empty, while the wlan usb stick notify all networks.
So I contact Toshiba service to get help.
