A software access point, also called virtual router or virtual Wi-Fi, enables a computer to turn its wireless interface into a Wi-Fi access point. It saves the trouble of getting a separate wireless router. You need a nl compatible wireless device, which supports the AP operating mode. This can be verified by running the iw list command, under the Supported interface modes block there should be AP listed:.
Creating a software AP is independent from your own network connection Ethernet, wireless, Many wireless devices even support simultaneous operation both as AP and as wireless "client" at the same time.
Using that capability you can create a software AP acting as a "wireless repeater" for an existing network, using a single wireless device. The capability is listed in the following section in the output of iw list :. Random MAC address can be generated using macchanger. Adjust the options in hostapd configuration file if necessary. See hostapd Linux documentation page for more information. When starting hostapd, make sure the wireless network interface is brought up first, otherwise it will fail with the message "could not configure driver mode".
Also make sure that the interface is not managed by a network manager. For automatically starting hostapd, enable the hostapd. The bridge approach is simpler, but it requires that any service that is needed by the wireless clients, in particular DHCP, is available on the computer's external interface. This means it will not work if the external modem which assigns IP addresses, supplies the same one to different clients. The NAT approach is more versatile, as it clearly separates Wi-Fi clients from your computer and it is completely transparent to the outside world.
It will work with any kind of network connection, and if needed traffic policies can be introduced using the usual iptables approach. It is possible to combine these two approaches: for example having a bridge that contains both an ethernet device and the wireless device with a static ip, offering DHCP and setting NAT configured to relay the traffic to an additional network device connected to the WAN.
Start and Grow AP
You need to create a network bridge and add your network interface e. You should not add the wireless device e. See Internet sharing Configuration for configuration details. In that article, the device connected to the LAN is net0. That device would be in this case your wireless device e. It combines hostapddnsmasq and iptables for the good functioning of the access point.
The basic syntax to create a NATed virtual network is the following:. This could be caused by low entropy. Consider installing haveged.
You can mask the device using MAC:. Apparently with the special country code 00 globalall usable frequencies in the 5Ghz band will have the no-ir no-initiating-radiation flag set, which will prevent hostapd from using them. You will need to have crda installed and have your country code set to make frequencies allowed in your country available for hostapd.

The old tool iwconfig, which uses Wireless Extensions interface, is deprecated and it's strongly recommended to switch to iw and nl Like the rest of the Linux kernel, iw is still under development.
Features are added 'as we go'. The only documentation for iw is this page and output from 'iw help'. Please help expand this page. There is a page listing use cases with iwconfig and iw: replacing iwconfig. Use the following to get device capabilities for all devices, such as band information 2.
To determine if you are connected to an AP or not and if you are the last TX rate used you can use the command below. This would happen if you are not connected to an AP. To connect to an AP you can use iw connect if the connection requires:. Suppose you have two APs with the SSID fooand you know the one you want to connect to is on the frequencyyou can specify the frequency to use:. If you want to get specific statistics against a peer you station is communicating with you can use the following:.
It does this by masking in the allowed bitrates, and also lets you clear the mask. Note that whether or not the device actually listens to your petition will vary depending on the device driver and cooperation from the firmware.
For example:. Note that the value this commands takes is in milli bel-milliwatts mBm instead of the commonly used deci bel-milliwatts dBm. To enable power save by default you can use:. For mac drivers this means Dynamic Power Save gets enabled. If your udev is configured incorrectly, the newly created virtual interface may be renamed by it right away, use. You can customize the type of monitor interface you create. This can be very useful for debugging purposes on end user systems.
For example, suppose you want to help a user. You can take advantage of the fact that a monitor interface in mac uses radiotap to pass up to userspace additional data.
Say we want to help a user fish out data without affecting the device's performance by setting it to a full monitor interface. A monitor interface with no additional monitor flags can be created as follows:. The nice thing about these type of alternative monitor interfaces is you can further extend radiotap even with vendor extensions to add more data to radiotap to help debug device specific features.Back to Top.
If you are setting up multiple UniFi devices, connect them together and launch the Setup Wizard. It will allow you to adopt all of the connected devices at once. If you are using a UniFi Dream Machine, which acts as a Cloud Key, switch and a gateway, your topology might look like this:.

UniFi Controller Hardware.After looking around a bit online, I found several people who claimed to have gotten this working, as well as posts saying it should work, based on the chipset. Despite my best efforts, I was unable to get any of those tutorials to work reliably on their own.
Before we can operate our access point, we need a device allocated for it, similar to how systemd allocates a wlan0 device at boot time. A number of tutorials I found claimed that the address for the virtual AP must be different from the primary MAC address.
UniFi - Getting Started
I found there to be no difference in behavior, but you should be able to change the last byte, for example, to give your client and AP different MACs. The device we created above is called ap0. Wait awhile, and this process should complete. The install process may automatically start the dnsmasq.
Disregard this for now. Next, we need to modify 3 files. Once again, notice we reference ap0 above, so use your device name here if you changed it earlier. You can substiute your own subnet here, but be sure to remember it for later, as it should match the static IP we assign your AP. The 12 hour lease time can also be arbitrarily changed to suit your needs. I found many different parameters that can go in here, but this is what worked for me.
Feel free to experiment further by poking around online. Lets do this for now:. This tells the hostpad daemon to use our new conf file. Next, we need to define our WiFi network interfaces, both for our managed access wlan0 and for our access point ap0. You should also change the country code to whatever is appropriate for your region.
UniFi - Getting Started
As you can see, we want both ap0 and wlan0 to start up automatically, with ap0 defined to have a static IP of Adjust accordingly if you made changes. We also reference our hostapd config file here, to direct the AP configuration for ap0.Ubiquiti UniFi AC In-Wall Access Point (UAP-AC-IW) : Unboxing \u0026 Installation Part 1
The wpa-roam designator will allow the interface to move freely between our defined networks. At this point, I expect everything to work after a reboot. After some tinkering, I discovered the following sequence of commands after a reboot would get both interfaces up and working simultaneously, like we wanted all along:.This last one is not a true separate product family: it will have a mixture of other lines.
They are displayed in a separate table because they are intended for specific cases and not really comparable to the regular, general-use APs. At the end of the article the UniFi Dream Machine is also listed because one of its features is to provide internet connectivity, but it is not strictly an access point.
Back to Top. The UniFi Finally, take advantage of the unlimited scalability: build wireless networks as big or small as needed. The UniFi AC AP family is comprised of the three access points shown in the table below as well as the specialty in-wall models and mesh models.
The UniFi AP SHD was released for high-density scenarios where data security must be monitored constantly, like banks and hospitals for example. The nanoHD joined this line to provide a smaller footprint solution with the same high-density goal in mind. When you use the 2. When using the 5 GHz band, the option is available to deploy smaller cells coverage areasso you can support more clients in an area that requires the deployment of more than one AP.
With flexible mounting options, the Flex HD can be deployed on tabletops, walls, poles, and ceilings. Just plug it into a wall outlet, the UniFi Network Controller discovers it automatically, adopt it and you're done. UniFi HD Datasheet. This is Ubiquiti's latest product line and what the future looks like. The specialty models shown below are devices that perform a very specific function not usually found in other products.
