i set up raspian os with recommended apps version on sdcard via noobs. it works on rpi successfully but without wireless connection.

  • in rpi configuration window, set wifi country button is disabled.
  • on the window top bar, when i click on the icon of wire connection

  • (up and down arrows) , a popup fades "no wireless interfaces found" "ifconfig" command returns only lo and eth0. no wlan0.

system is up to date. i've already updated and upgraded the apt and the os. thanks.

    The Pi2B does not have onboard wifi. Do you have an usb wifi adapter plugged in? – Dirk Mar 30 at 18:23

    googe bcm2836rifbg and you get raspi.tv/2015/raspberry-pi-2-the-new-quad-core-a7-pi2 - it's the CPU of the older Pi2 - the newer ones have bcm2873 like the pi 3 - but even then, do not have onboard wifi – Jaromanda X Mar 31 at 2:23

A RasPi 2B does not have an on-board WiFi chip, so what you see, that it isn't available, is all right. Look at Raspberry Pi - Generations of released models that a Raspberry Pi Family 2 Model B does not provide Wireless. To use WiFi you need an additional USB/WiFi dongle.

  • @gks I don't have a RasPi 2B so I cannot say what this bcm2836rifbg do. You may google it. But it does not provide WiFi. I have updated the answer with additional info about the model. – Ingo Mar 30 at 18:41
