Configuring a NanoStation as an AP

Submitted by tarvid on Sun, 09/25/2016 - 12:52

By default, a NanoStation wants to be a “station” or client. The screen shots below are after configuration. That’s good in that my NanoStation is working as an AP and bad in that it doesn’t show the fumbling I did to get there. Out of the box with your laptop connected to the primary port and your IP address set to 192.168.1.2, enter 192.168.1.20. Log in as ubnt password ubnt. You can’t change anything on the MAIN page but it is a partial checklist before you quit.

The real work begins on WIRELESS. It will come up in “Station” mode and act like it desperately wants to go back there. You must get into “Access Point” mode.

The SSID is the default. Do not “hide” SSID. The Country Code is “United States”. If you get enough APs going to get confused you might start naming them.

 

The best IEEE mode we are going to get out of this NanoStation is b/g mixed. 20 Mhz bandwidth will get us the best transfer rate. Leave Channel shifting Disabled.

 

I chose Channel 1. There are three non-overlapping channels on the 2.5Ghz band - 1, 6 and 11. If you are the TWR network, they will have already chosen one of those. You neighbor may have chosen another, pick the one with the least competition.

 

Leave Output Power on “max” - 26dbm or 400 milliwatts. Not enough to make toast but I would stick the antenna in my ear.

 

Set WIRELESS SECURITY to none. That is a totally separate project we don’t have to address now.

 

Click “Change” at the bottom and then “Apply” when prompted at the top. Do not leave this page until AP mode sticks.

 

This is where the fun begins. Chose Network Mode - Router. Bridge is neat but, every station that connects will try to get an IP address from upstream. Most providers will give you a finite number of connections (e.g. 5).network.png

 

I chose 192.168.10.0 as the network and 192.168.10.1 as the WLAN IP with as mask of 255.255.255.0. This is called a “Class C” network which will give us 254 possible addresses of which 100.199 are allocated to DHCP. All clients will get an IP from this pool. We do want to enable NAT (Network Address Translation)  - that allows our clients to get out to the Internet. Auto IP Aliasing gives us one more way to get back in the NanoStation. We want to hand out IP addresses automatically so we turn on DHCP and set the pool. DNS proxy allows the NanoStation to pass DNS requests upstream.

 

The only additional service I added was NTP to the default time server, This keeps the logs in sync with the real world.services.pngsystem.png

 

Make sure you clicked “Change” on every page on which you made changes and “Apply”.

 

A speed test will confirm our configuration locally. A Logout and Login will check to see if changes were written but nothing is more convincing than a power bounce. Note your NanoStation will come up at the new address 192.168.10.1 and your laptop will reassociate on the new network.speedtest.png

 

Happy trails to you
