since my other thread was closed: ZTE K3806-Z 3G RHEL 6
I opened a new one:
Did anyone managed to bring the ZTE K3806-Z modem to life (with vodafone) on RHEL 6? How to do it?
this first part is needed because linux needs to see this device as a modem, not as an usb storage:
install wvdial (usb_modeswitch is needed to recognize the device as a 3g modem)
plug in the ZTE K3806 USB 3G modem, see dmesg messages, just type "dmesg" in the command line:
if PIN is: 1234 - modifiy the PIN:
chmod 666 /etc/ppp/peers/wvdial
plug in the ZTE K3806 modem & network manager will pop-up for PIN, type the PIN then modem LED turns blue..
If it didn't asks for PIN.. then try to modeswitch it to a modem with the sakis3g!
as user in a console:
if wvdial says "/dev/ttyACM0 is busy" then disable network in nm-applet (networmanager) - because probably that's the app that keeps it busy:
8) update /etc/resolv.conf if there isn't any DNS! (hint with example IP's):
