Reset to default

In the terminal, type:

sudo apt update # update the software database

sudo apt install dnsmasq-base # install dnsmasq-base

nm-connection-editor # start the GUI editor

Click the + button to create a new connection... choose Wi-Fi...

Set up this window, including the MAC address of your USB dongle... if the USB dongle is currently inserted, you can just use the pull-down menu to enter the MAC address for you...

Update #1:

Set the Band to 2.4ghz, and the Device to the proper MAC address of the USB dongle (use the pop down menu to select).

  • @SatishChandra If you're choosing "connect to hidden wifi" then you're not following my instructions. Please re-read the steps. Also, once the hotspot is running, you go to another computer, and connect to the hotspot wi-fi just like you do when you connect to any wi-fi network.

  • In the wifi setting I can see two driver(in two different tab) 1. AR9565 Wireless Network Adapter (PCI wifi adapter) 2. 802.11 n WLAN (USB) wifi driver. When I clicking the Turn On Wifi Hotspot even if from 2nd tab the hotspot is getting created and shows up in first tab, I think the hotspot is getting created by using PCI driver and not the USB one. and because the PCI driver is not working I can not see the network in my phone
