Can't use hostapd to create wifi hotspot

tris_halo · 08-02-2013, 01:06 PM

My device is my phone using Android OS. And now I'm trying to create a network using hostapd (authenticator and stuff) and dnsmasq (DHCP service).
- Here is the default hostapd.conf file of system:

Code:

interface=wlan0
driver=nl80211
ctrl_interface=/data/misc/wifi/hostapd
ssid=TrisAP
channel=6
ieee80211n=1
wpa=1
wpa_pairwise=TKIP CCMP
wpa_psk=1e1981e8d8b6922b1717cbc2bcdf1d7395cb53750317beb88a4dfaa56301ca22

- I am using the following command

Code:

hostapd ./hostapd.conf

And yes, the hostapd process is created. But still another devices such as my laptop can't see my network. Please help me

Nothing to help you WITH. What you're trying to do is called 'tethering', and (since you've only got one WiFi transceiver on your phone), you can only use it in one place. So, if you're connected to WiFi with your phone, it's busy and can't be used. If you're not, then your carrier may have disabled tethering, which means you can't do it.

Also, you don't tell us what kind of phone, running what Android OS, on what carrier, so there's little we can tell you. Most phones will have a tethering option built in (IF it is supported by your hardware and carrier), and you can just enable it through the settings menu.

- Thanks for your support. I figured out my answer. My problem is I want to have the "tethering" function which is separated from built-in function using Linux commands (not the API). I currently want to develop an tethering application for android OS. The commands I use are:
ndc softap fwreload wlan0 AP
ndc softap startap

- At first I simply use hostapd commands but it doesn't work. It shows out "missing beacon parameters and failed". The above commands help creating hostapd process automatically.
- Thanks for the reply anyway.
