How to set up a wi-fi hotspot with an Ubuntu laptop (access point mode)?

rated 0 times [ 6] [ 0] / answers: 1 / hits: 63035 / 3 Years ago, wed, june 23, 2021, 5:50:42

I've read this article, and carefully followed the instructions provided. I am sure the wireless card in my laptop supports going into wireless access point mode.

But unfortunately, when I use the following command to start hostapd service it throws an error:

 $ sudo service hostapd stop

 Starting advanced IEEE 802.11 management hostapd                      [fail]

The instructions mentioned above said this could possibly be because my wireless card does not support the g mode, and provided the wiki of hostapd.

But what is g mode? I tried to switch to a, or b mode, but it just didn't work.

Can anyone help with this or recommend a tool like connectify in windows ?

ps. I am using Ubuntu 12.04, 32 bit. I have an ADSL wired network, and I want to share it by setting my laptop into a WiFi hotspot with my windows phone.

Since ap-hotspot is deprecated, it's neither reliable or stable for newer Ubuntu distribution. The author of ap-hotspot recommended create_ap.

Installation

git clone https://github.com/oblique/create_ap

cd create_ap

make install

Usage

No passphrase (open network):

create_ap wlan0 eth0 MyAccessPoint

WPA + WPA2 passphrase:

create_ap wlan0 eth0 MyAccessPoint MyPassPhrase

Change wlan0 and eth0 to the interface on your machine. (ifconfig)
