Guten Tag,
ich brauche mal eure Hilfe. Ich hab meine Pcmcia W-lankarte mit dem ndiswrapper laufen und bin mit meinem Router verbunden. Ich kann mich selbst pingen aber den Router errecihe ich ncht. Die IP von meinem Router lautet 192.168.1.1 mir selbst habe ich die IP 192.168.1.7 gegeben.
Wenn ich nun in die route gehe kommt folgendes:
192.168.1.0 * 255.255.255.0 U 0 0 0 wlan0
link-local * 255.255.0.0 U 0 0 0 wlan0
loopback * 255.0.0.0 U 0 0 0 lo
default 192.168.1.1 0.0.0.0 UG 0 0 0 wlan0
Bei /sbin/ifconfig:

Und bei cat /etc/resolv.conf:

Was ich noch dazu sagen muss, ich bin noch ein einigermasener Anfänger.
Vielen Dank im Vorraus,
Kai Fischer
Ich hab noch was, wenn ich
cat /proc/sys/net/ipv4/ip_forward eintippe kommt eine 0 als Ergebnis.
Ich hab mal das Script collectNWData.sh ausgeführt:
