The migration from 7->10 destroyed your WiFi driver.

Go to the Toshiba Site, support, drivers and download the win/10 version of wifi
 
Have you checked under "Unknown Device" in "Device Manager"? If not, please check if the Wireless card is listed there. If you are not able to see the Wireless Card in the Device Manager, the wireless card might not be detected by the system. Take a technician's help or by yourself try to re-seat the Wireless Card (refer Service Manual for detailed steps on how to remove the wireless card and safety tips). The WLAN Mini-Card slot on the Inspiron N5110 / 15R system is located at the bottom of the palm rest.
