To setup the interface, type: # iface wlan0 upДЄnd try the network sending a ping to the gateway: # ping 192.168.1.Uncheck Allow computer to turn off this device to save power option.Д¬.

Pre-up wpa_supplicant -B -Dwext -iwlan0 -c/etc/wpa_nf The next step is to include the ip address, etc, and tell the system to use wpa_supplicant when we need it. You can see it like that you plugged the cable on the switch. We copy and paste the psk key to our configuration.ДЄt this point, we have a link between our wifi card and the access point. this will genreate something like: # wpa_passphrase test_ssid supersecret Wpa_passphrase is a simple command that will generate the key for authentication. We will configure a /etc/wpa_nf with all the networks and passwords that we use. We need the package wpa_supplicant that will stay resident while our interface is connected. I assume your router is using WPA2 for encryption. Now it is time to associate our wireless card to the access point. To check if we are connected to the access point (we are not) : # iw dev wlan0 link To list the available networks, type: # iw dev wlan0 scan You can see more info with: # iw phy phy0 info Ok, now you have a working wireless network card. If your hotplugger is not correctly configured, the system will hang up for a whileвЂ¦ check that /dev is correctly populated and your filesystem is mounted, etc.

To bring the device up # ip link set wlan0 up Tocheck that your device exists: # iw list To enable the driver, type # modprobe rt2800usb Ok, now, copy the latest firmware to /lib/firmware, and setup the interface Before you can tell to the kernel that you will use mdev as your device manager, you must mount the sysfs, and setup the kernel вЂhotpluggerвЂ™ : # mount -t proc proc /proc

But with our small system, this is not so easy, because the kernel must have some access to the filesystem.ДЇorВ an embedded device there are some ways to do it.В Busybox has a system called mdev to dinamically update the list of devices. The system will upload the firmware to the device automatically. This device has a proprietary firmware that must be uploaded when you setup the interface. The next step is to bring the interface up. rt2800usb - Include support for unknown (USB) devicesДЄlso, remember to enable all the obvious things, like network support, tcp support, etc. rt2800usb - Include support for rt33xx devices Ralink rt27xx/rt28xx/rt30xx (USB) support

So, if you compile the kernel by yourself, enable the driver here: Device Drivers -> This device hasnt any network card (it cost 35 euros), but fortunately I got an old usb wifi card, an Ovislink evo-w300usb, that internally comes with a chip from ralink, the 2870. The idea of this howto is to have a, more or less, clear idea of all the steps that you need to connect your wifi card, step by step. It is running and I really love it! It is time to connect it to the LAN. I am playing with my a13 olinuxino micro. Setting up an USB wireless card from scratch
