Re: Lenovo L440 Can't turn on the Wlan

Hi L440problem! Welcome to our forums community. When was the last time it worked properly? Have you made any changes or any updates before the issue arise? Kindly check if the Airplane mode is turned off:--> click Settings --> Network & Internet --> Airplane mode. If the issue is the same, check the wireless driver under the device manager if there is an error or is it grayed out. If not, uninstall and restart the computer. Update us on how it goes.

Have you tried Fn + F8 to enable the wireless feature? As per the user guide: https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/l440_l540_ug_en.pdf, page 27.
