Debian 8.5 is installed on the laptop with gnome. When installing the system for some reason, the drivers for wifi were not installed (the kernel did not contain) and therefore the list of wifi networks did not appear in the top right menu. Through the usual LAN internet connection is.

typing

lspci | grep -i wlan lspci | grep -i wlan is lspci | grep -i wlan

    Put one first, reboot. If it does not help, delete, reboot and install another one. - don Rumata
  • @donRumata if the wrong driver is supplied nothing breaks? what problems may arise? - ampawd

    In 99% nothing. In the remaining 1%, anything can happen, vpolt before the explosion of the nearest nuclear power plant or the thermal death of the universe. So if the news slip something about the impending black hole - we will know who (and whose laptop) to blame. - don Rumata
  • iwlwifi as far as I remember for Intel, and you have broadcom. In addition, these packages do not contain drivers (most likely they bring dependencies, and that’s not a fact). - 0andriy
