Raspberry Pi WiFi
Source : Alex Schroeder: Diary
Reading Raspberry Pi: WLAN einrichten… I bought the Nano-WLAN-USB-Stick 150 Mbps by hama.pi@raspberrypi ~ $ lsusb Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter pi@raspberrypi ~ $ sudo apt-get install firmware-realtek Paketlisten werden gelesen... Fertig Abhängigkeitsbaum wird aufgebaut. Statusinformationen werden eingelesen.... Fertig firmware-realtek ist schon die neueste Version. 0 aktualisiert, 0 neu installiert, 0 zu entfernen und 0 nicht aktualisiert.Apparently I installed it already. iwlist wlan0 scan results in a lot of output. Including the network I’m looking for:pi@raspberrypi ~ $ iwlist wlan0 scan | grep Schroeder ESSID:"Schroeder"Set your network and password using sudo nano /etc/wpa.conf. This is what you want:network={ ssid="YOUR-SSID" proto=RSN key_mgmt=WPA-PSK pairwise=CCMP TKIP group=CCMP TKIP psk="WPA-PASSWORD" }Edit the list of interfaces using sudo vi /etc/network/interfaces and append the following:auto wlan0 iface wlan0 inet dhcp wpa-conf /etc/wpa.confI was astonished to find some stuff relating to wlan0 in the file already. Anyway, I followed the instructions…Restart and check:pi@raspberrypi ~ $ ifconfig eth0 Link encap:Ethernet Hardware Adresse b8:27:eb:81:a6:af inet Adresse:192.168.2.3 Bcast:192.168.2.255 Maske:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metrik:1 RX packets:114 errors:0 dropped:0 overruns:0 frame:0 TX packets:94 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:1000 RX bytes:17450 (17.0 KiB) TX bytes:14232 (13.8 KiB)

wlan0 Link encap:Ethernet Hardware Adresse 80:1f:02:8f:91:26 UP BROADCAST MULTICAST MTU:1500 Metrik:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)The last entry is shows that we didn’t get an IP number. Oops! It turns out that there is some other stuff in the /etc/network/interfaces file that might interfere. Commenting them out, I have:auto lo
iface lo inet loopback iface eth0 inet dhcp
# allow-hotplug wlan0 # iface wlan0 inet manual # wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf # iface default inet dhcp
auto wlan0 iface wlan0 inet dhcp wpa-conf /etc/wpa.confStill doesn’t work, however. I tried a few variants for the config files. Nothing seemed to work. This makes me so tired. I’m not sure I’m learning much. This is “fiddling with GNU/Linux” and frustrating [..]
