Please Don't mark it as duplicate. I recently move to Linux from Windows. I installed Ubuntu 18.04 in my PC. Now I want to create wifi-hotspot in my Ubuntu-18.04 to share internet with my android phone. I've watched several tutorials and read many articles about But still I'm not able to create wifi-hotspot. Could any please guide me to do that? I'll be thankful to him/her :)

  • If hotspot doesn't work, check for its driver. your wifi module may not be well-supported. – mohammads Sep 10 '18 at 13:26
  • Could you please guide me how to check drivers? – hassanrazadev Sep 10 '18 at 13:39
  • check the output of lspci -vvnn | grep Network and lshw -C network then find your wifi vendor, check the chipset and driver from https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported – mohammads Sep 10 '18 at 13:46

  • Your chipset(Intel Advanced-N 6200) is not supported according https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsIntel. this may help you https://ubuntuforums.org/showthread.php?t=2274562, or maybe this https://askubuntu.com/questions/675352/wireless-disconnects-intermittently-with-intel-corporation-centrino-advanced-n-6 – mohammads Sep 10 '18 at 13:54
  • @Mohammads His wifi chipset is perfectly well supported by the driver iwlwifi, despite the outdated link you gave. The question is whether the driver supports AP mode. Find out with the command: iw list Does it show: "Supported interface modes:
    • IBSS
    • managed
    • AP
    • AP/VLAN
    • monitor
    • P2P-client
    • P2P-GO
    • P2P-device"

  • I was using wifi-hotspot in same PC on window 7. So, it's not happening here? – hassanrazadev Sep 10 '18 at 16:07
  • See my answer in a few minutes. – chili555 Sep 10 '18 at 16:08
  • Sure I'm waiting... – hassanrazadev Sep 10 '18 at 16:10
  • @chili555 Try for using iwlwifi wasn't successful, check the forum https://ubuntuforums.org/showthread.php?t=2274562. – mohammads Sep 10 '18 at 16:25
  • @Mohammads That's not a driver issue, it's a router issue. As far as is evident here, the OP connects perfectly well to his router with iwlwifi as do I with my Intel device. – chili555 Sep 10 '18 at 16:29
  • @chili555 Oh, you're right. The STA mode is fine! – mohammads Sep 10 '18 at 16:33

After you ran the terminal command:

iw list

You found:

 Supported interface modes:
     * IBSS
     * managed
     * monitor

Not every device supports every mode using Linux drivers. In many cases, perhaps most, there are modes that work perfectly well in Windows or even macOS, that don't work at all in Linux.

Footnote: It is perfectly possible, barring a whitelist, to swap out your device to get other features support as I have. For an example, my device: Intel Corporation Wireless 7260 [8086:08b2] (rev 83) reports the following:

Supported interface modes:
     * IBSS
     * managed
     * AP
     * AP/VLAN
     * monitor
     * P2P-client
     * P2P-GO
     * P2P-device
