Good afternoon.
Toshiba satellite l15w-b1208x
The laptop started to misbehave from the moment of purchase. About guarantee you can not to say there are difficulties with this.
About the problem:
Using the Internet or not throws an error

Then the Internet is lost and funny - falling off the USB. Neither the flash drive and the external network wi-fi adapter not detected. Tampering with the network adapter in the network settings do not lead to anything. He just doesn't turn on until you reboot the laptop.
What could be wrong ? Where to drip?
Driver re-installed on the wi-fi module from the official website.
