Robotino v3

The next generation Robotino will use an USB WLAN stick to either connect to an access point in client mode or provide a access point external clients can connect to in master mode. Various WLAN USB adapters are supported. The following list shows the USB sticks tested to work in both client and master mode:

  • AVM Fritz!WLAN USB Stick N (supports a/b/g/n)
  • TP-Link TL-WDN4800 (PCIe-adapter, supports a/b/g/n)

The following adapters are known to work at least in client mode:

  • Alfa AWUS036EW USB WLAN Stick (support for b/g)
  • Alfa AWUS036H USB WLAN (support for b/g)

WLAN master

The WLAN master on Robotino is run by hostapd. A german how-to on setting up a WLAN router using hostapd can be found here. Additionally a DHCP server is running assigning IP addresses to clients connecting to Robotino's access point.

When running as WLAN master Robotino has the fixed IP address with netmask The DHCP server assigns addresses in the range to



If your network adapter supports 5GHz WLAN you can setup your system to use this frequency by manually editing /etc/hostapd.conf


After saving your changes restart the wlan interface

ifdown wlan0
ifup wlan0

WLAN client

In client mode the WLAN interface of Robotino connects to an external accesspoint. Robotino can be assigned a fixed IP address or can obtain an address from an external DHCP server.



Remember that eth0:10 is preconfigured to If this is in conflict to your settings for eth0 you might want to disable eth0:10 in /etc/network/interfaces.
