Do you want to make a computer function as a WLAN base station, so that other computers can use as it as their wifi access point? This can easily be done using the open source software Hutorial and compatible wifi hardware. This is a useful thing to do if computer acting as a firewall or as a server in the local network, hostapr you want to avoid adding new appliances that all require their own space and cables in you already crowded server closet. Hostapd enables you to have full control of your WLAN access point and also enhances security.

By using Hostapd the system will be completely in your control, every line of code can be audited and the source of all software can be verified and all software can tutorkal updated easily. With a proper Linux server admins can easily SSH into it and run upgrades using the familiar and trusted upgrade channels that Linux server distributions provide.

The first step in creating wireless base station with Hostapd is to make sure the WLAN hardware supports running hosatpd access point mode. Examples are listed in the hostapd documentation. The next step is to install the software called Hostapd by Jouni Malinen and others. This is a very tutofial used software and it most likely is available in your Linux distribution by default.

Many of the WLAN router appliances available actually are small Linux computers running hostapd inside, so by running tutkrial on a proper Linux computer will give you tutroial least all the features available in the WIFI routers, including advanced authentication and logging. Our example commands are for Ubuntu To start simply run:.

The relevant parts for a simple WPA2 protected Next you need to edit the network interfaces configuration to force the WLAN card to only run in the access point mode. Assuming that the access point network will use the address space Then we need to have a DNS relay and DHCP server on our wlan0 interface so the clients actually get a working Internet connection, and this can be accomplished by configuring dnsmasq.

Hostapd : The Linux Way to create Virtual Wifi Access Point

Next we need to make sure that the Linux kernel forwards traffic from our wireless network onto other destination networks.

We need to activate NAT in the built-in firewall of Linux to make sure the traffic going out uses the external address as its source address and thus can be routed back.


If you have such hardware you might need to also run rfkill to enable the hardware using a command like rfkill unblock 0. Now all configuration should tuyorial done. To be sure all changes take effect, finish by rebooting the computer.

If everything is working, a new WLAN network should be detected by other devices. We are sorry to hear your computer does not work properly.

Turn any computer into a wireless access point with Hostapd – Seravo

The instructions above are very technical and meant for experts as advice on how they can achieve a cool ability with a computer. Before trying out such instructions please back up at least the configuration files so you can revert back to the old settings if something does not work. At the moment the best advice is to find an affordable local Linux expert, explain to him in detail what you did and he can then hopefully fix your computer. I need to create an acces point on the wlan0 and redirect the traffic on eth0.

If Tutoial modify just the iptables instruction normally it should works? The destination is not the same as the source. It is everything but the source. Not the exclamation mark! Hsotapd, thank you for this very useful guide.

My desktop is connected to the internet by an ethernet connection with a static ip. I like to share this connection by the wlan1 usb wifi dongle.

I never set up a user name in any configuration file. Thank you for the quick reply. I forgot to remove the EAP parameters in the string: The configuration file reads like:. I tried these tutoriap with Ubuntu I tried simply leaving out those two options, but as soon as i bring the interface up, i lose access to the system hostapv ssh. I do obviously already have a wired connection to the system, but that goes down as well. I am assuming its because it would be two interfaces then on the same subnet and that causes confusion?

Any suggestions on accomplishing my needs? You can leave off the dhcp3-server package http: For unknown reasons it messed up my routing table and added a I set it up on a OLinuXino box running Debian 8 jessie.

It works fine with two of my Android phones. Trying to associate with I followed your guide and everything seemed to be perfect. I used my built-in wifi card in my laptop. How can I create it? After using this tutorial, your wifi will not be able to connect to other network, it will be running only as AP. You cannot both use it to connect laptop to router and also use laptop as router, you need 2 wifi cards to be able to do that. It worked fine on my laptop Toshiba, AR — ath9k driver default drivertried it in the last few days on Ubuntu The network applet crashed, but it is quite simple to configure the internet network event without it, in System Settings.

As both have Intel in it. By using that tutorial, will it be possible? Your tutorial is really great, it works! I have tested it on Ubuntu There is only one probably bug that will occur: I wanna build a powerful WiFi access point machine, using the tutorial above, but one thing is missing!


I recommend selecting something from here: Local Loopback inet addr: If I have an USB adapter wifi like the source of internet wlan1 tplink and I want to reply this signal with the atheros wlan0 tktorial may look my configuration? tutorual

Can anyone please tell me, how many clients can i connect with it to my access point?? I am actually designing a linux based wifi access point to connect minimum tutoriwl. Please help me out with this. Hi Otto, Few questions: So, does hostapd sill necessary?

Other question, how to do if I want to created a standalone webserver accessible via wifi? Thank you for the tutorial. It worked fine for some clients — Android was able to access network at once, but Ubuntu asked for username, etc instead of only password. I also installed DHCP server tuforial following the instructions at http: Just wanted to say thanks.

Just so everyone else knows what I did. I plugged a netowrk cable into the network adapter on the Pi and put the usb dongle in there. This put a file named ubuntu-mate I had to run this as an Administrator for it to work.

This merely extract the.

This took a while. It took a while to boot up and it tool a long long time for the configuration to complete 20 minutes, easy.

I did the following sudo apt-get update sudo apt-get upgrade this took 40 minutes. How do I fix this? I have found that the network interface does not launch this by default, so running it again, enables AP mode. Operation not supported Could not enable hostapd mode for interface wlan1.

Just wanted to thank you for the excellent tutorial. Worked perfectly for me. I just had to adapt some things to my system like IP number, iptables, etc. This was the first tutorial about hostapd I found that included configurations of dnsmasq, sysctl, Network Manager and rc.

There are so many options in the hostapd including the WPS stuff which has caught my eye and I might look in to. I have openwrt on a kvm and would like to use hostapd as the wlan for my openwrt. I literally copy pasted and only ran into one hurdle.

The example passprase length not being long enough. I have a dlink adsl router which is installed in living room. I connect my laptop to it and get a good signal. However, when I go to my other room which is two rooms after, the connection is very weak.

I have an ubuntu file server setup in my 3rd room. This ubuntu is connected to dlink wifi through usb wifi.
