I am unable to start hotspot in access point mode in my Kubuntu 16.04.1 version. I have installed it recently and is fully updated. My wireless driver is:

02:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

and the result of command iw list is:

How do I get my wireless driver to support AP mode? I can start hotspot in ad-hoc mode but it is not detected in any devices except one it is hosted from. And I am unable to start hotspot in access point mode. How do I start hotspot in access point mode?

In the data you posted, under "Supported interface modes," AP mode is not listed. The proprietary driver bcmwl-kernel-source does not support AP mode.

I am unaware of any other driver that is available that correctly drives your device and supports AP mode.

For reference, here is the corresponding output from another device that does support AP mode.

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

  • Does that mean that I can't create access point hotspot in my laptop? Because I can create hotspot in my Windows 10. What is the possible issue with my driver? Aug 29, 2016 at 13:59
  • Can you at least suggest any source or person who can help me with it? I really like Kubuntu os and it is necessary for me to make the hotspot work. Aug 29, 2016 at 14:10
  • I know of no such resource. The hardware/driver/os combination are not designed nor capable of doing what you are asking. You could always just get a different device.
