As many of you know, most of our android(not only android) devices can't connect to ad hoc hotspots. There's a solution for win7/8 users to set up infrastructure hotspot on their laptop using software like connectify and so on. Ubuntu also allows to create wifi hotspot to share internet, but it will be ad hoc one.
So here's the guide how to set up infrastructure hotspot on ubuntu 12.04/12.10. Unlike some other methods described on the internet, this one will not break default network manager.
1. First of all you should make sure, that your wifi adapter supports infrastructure hotspots. If you used connectify on your windows system and it worked, skip this step.
open terminal and type: sudo lshw | less
find -network section and make sure that driver is ath5k or ath9k, this solution will only work for those drivers, but should fit the needs for the most laptop users.
2. We now need to install 2 additional tools to make out hotspot, 1st one is hostapd(hotspot server), 2nd one is dnsmasq(dns dhcp server)
in terminal type: sudo apt-get install hostapd dnsmasq
3. stop those services if started already, and prevent them from starting on system start up.
in terminal type:
sudo service hostapd stop
sudo service dnsmasq stop
sudo update-rc.d hostapd disable
sudo update-rc.d dnsmasq disable
4. Now we need to set up config files.
in terminal type: sudo gedit /etc/dnsmasq.conf
or sudo kate /etc/dnsmasq.conf if you use kde
add those lines to the config file
Code:
# Bind to only one interface
bind-interfaces
# Choose interface for binding
interface=wlan0
# Specify range of IP addresses for DHCP leasses
dhcp-range=192.168.150.2,192.168.150.10
5. hostapd config
in terminal type: sudo gedit /etc/hostapd.conf
and add those lines
Code:
# Define interface
interface=wlan0
# Select driver
driver=nl80211
# Set access point name
ssid=myhotspot
# Set access point harware mode to 802.11g
hw_mode=g
# Set WIFI channel (can be easily changed)
channel=6
# Enable WPA2 only (1 for WPA, 2 for WPA2, 3 for WPA + WPA2)
wpa=2
wpa_passphrase=mypassword
You can change ssid name and password for anything you want here. Current config will create hotspot named myhotspot with mypassword password.
6. Now create anywhere you want a file named start.sh
edit it with any text editor like this:
Code:
#!/bin/bash
# Start
# Configure IP address for WLAN
sudo ifconfig wlan0 192.168.150.1
# Start DHCP/DNS server
sudo service dnsmasq restart
# Enable routing
sudo sysctl net.ipv4.ip_forward=1
# Enable NAT
sudo iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
# Run access point daemon
sudo hostapd /etc/hostapd.conf
# Stop
# Disable NAT
sudo iptables -D POSTROUTING -t nat -o ppp0 -j MASQUERADE
# Disable routing
sudo sysctl net.ipv4.ip_forward=0
# Disable DHCP/DNS server
sudo service dnsmasq stop
sudo service hostapd stop
You will probably need to change ppp0 in this to eth0 (or any other number which refers to your wired connection.
7. Last step. Now you can start your hotspot by starting our script. just run it using sudo sh
for me it looks like this sudo sh /home/ogyct/Desktop/start.sh because I have it on my desktop
I am not sure who is the author of this guide, I only translated it to english. But anyway if this helped, hit the thanks button. Good day
Android device having issues connecting to AP
I have an eth0 connection running behind an authenticated proxy server.
I followed the steps and managed to create a hotspot which my google nexus 7 detects. However, it seems stuck at "obtaining an ip address" and is not able to connect to the internet.
I initially received the following error message when running your script in the terminal:
dnsmasq: failed to create listening socket for 127.0.0.1: Address already in use [fail]
I figured it is because of a conflict with the network manager, I commented out the "dns=dnsmasq" line in the nm configuration file. After a network-manager restart, the first error doesn't show up but I get the following:
Configuration file: /etc/hostapd.conf
Failed to create interface mon.wlan0: -23 (Too many open files in system)
Try to remove and re-create mon.wlan0
In both cases, however, the hotspot is created and is detected by my android device. only that it cannot "obtain an ip address" and connect to it.
Is it because my eth0 connects via a proxy server?
Or could there be something wrong with the dnsmasq config? Any help would be appreciated.

I've never worked with a proxy server, but from what I see, it seems like your problem has nothing to do with a proxy server. Something's wrong with configuration on wifi side. Try to disable network manager first, if it doesn't help, try to completely clean dnsmaq and hostapd configs and paste code from this thread again. Unfortunately I can not provide any further help, since I have a different configuration on my side.
My galaxy s2 is able to see the "myhotspot" network created following this guide. I set a static ip and gateway to make it obtain an ip address.
Now it seems to be connected, but I have no internet access on my phone...
Could anyone help me?

I am using ubuntu 12.04 and I just figured out the instructions on ".../questions/180733/how-to-setup-a-wi-fi-hotspot-access-point-mode/" (askubuntu) thread worked like a charm for me. It uses the isc-dhcp-server instead of dnsmasq and a different dhcp range I guess. I really don't know enough to tell the difference but it worked. Maybe ogyct can explain it to us.

If everything's made right, there'll be no need for setting static ip adress, dhcp will do it for you.
Try to check if your devices are called wlan0 and eth0, if not, change configs accordingly. Simply type in console iwconfig to see the names. Remember, you may have a different configuration of your system, so be aware of that
HI ogyct,
This is the error i received.

BCM4313 doesn't support AP
You wireless card doesn't support the AP operation mode. You can look up on the hostapd support website and there is a list of suppored devices. The BCM 4313 is part of brcmsmac which is in the NO section for AP. You would need to get a new card or purchase an external wifi card. Hope this helps.

sudo service dnsmasq restart
# Enable routing
sudo sysctl net.ipv4.ip_forward=1
# Enable NAT
sudo iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
# Run access point daemon
sudo hostapd /etc/hostapd.conf

# Disable NAT
sudo iptables -D POSTROUTING -t nat -o ppp0 -j MASQUERADE
# Disable routing

This is running awesome. Just one question. How do I stop the script?
I find disabling and enabling wifi works. But is there any other way?
Hi, this script works perfectly. I was having issues with ubuntu shared wifi not being visible with android.
Now the hard question. I have a box that is already acting as a router sharing ip with dnsmasq over eth1
i added a wifi card wlan0 and i want to share not only internet but also the services running on my box
the problem is this script uses a different ip range and i cannot access my nfs shares.
my network is 192.168.128.x and i have set up this script in other range.
Setting it up in 192.168.128.10x for instance will not work
Is it possible to make this wifi share part of my network?
regards.
worked !!!

A little update, I am glad if this guide helped. but in case it didn't try this one http://www.webupd8.org/2013/06/how-to-set-up-wireless-hotspot-access.html. I didn't check this myself, but that script seems to be smart.
Is there a way to "permanently" set the mac address of wlan0 to something of my choosing? I have been able to do this temporarily through ADB and with busybox, but it does not always work. I want to have a specific mac address on wlan0 for when I use my phone as a hotspot for portable gaming devices. I have google's this, and it seems at least in previous versions of CM, this was stored in a file and could be changed, but I cannot find that file on the build I am running (CM 12.1-20150705-NIGHTLY). Does anyone know how to do this? Currently, I have to enable the hotspot, use ADB cli like:
# busybox ifconfig wlan0 down
# busybox ifconfig hw ether 00:11:22:33:44:55
# busybox ifconfig wlan0 up
# busybox ip link show wlan0
If I check the mac address after this, sometimes it changes, sometimes it does not. And sometimes when "ip link" reports the changed mac, it is not really changed (I check with other devices and they still see the old mac). But it does work... sometimes (rarely.. but I have had it working). I'd really like to make this more permanent.
I have looked in /data/misc/wifi but I don't see any nvram file in there anymore where I think you used to be able to set it.
This thread may help you. http://forum.xda-developers.com/showthread.php?t=2286440 I haven't tried it myself but a friend of mine said it worked for him.

It sounds like you are making a connection to your FireTV from a new device (your computer). When you do this, an authorization prompt should appear on the FireTV, press ok to give your computer authorization to access your FireTV.
If the authorization prompt is not appearing on your FireTV make sure you have ADB debugging turned on in the FireTV settings menu
Try the following steps to speed up your firestick:-
Restart/Reboot Your FireStick
Remove Unwanted Apps
Clear Cache of Apps
Keep Your FireStick Up to Date
Disable Automatic App Updates
Turn Off Collect App Usage Data
Factory Reset
