MF 622 with U mobile network in centos 5.

hmm..

create a rule file into the /etc/udev/rules.d/

with following content.

######### Start #################

ACTION!=”add”, GOTO=”ZTE_End”

# Is this the ZeroCD device?
SUBSYSTEM==”usb”, SYSFS{idProduct}==”2000″,
SYSFS{idVendor}==”19d2″, GOTO=”ZTE_ZeroCD”

# Is this the actual modem?
SUBSYSTEM==”usb”, SYSFS{idProduct}==”0001″,
SYSFS{idVendor}==”19d2″, GOTO=”ZTE_Modem”

LABEL=”ZTE_ZeroCD”
# This is the ZeroCD part of the card, remove
# the usb_storage kernel module so
# it does not get treated like a storage device
RUN+=”/sbin/rmmod usb_storage”

LABEL=”ZTE_Modem”
# This is the Modem part of the card, let’s
# load usbserial with the correct vendor
# and product ID’s so we get our usb serial devices
RUN+=”/sbin/modprobe usbserial vendor=0x19d2 product=0x0001″,
# Make users belonging to the dialout group
# able to use the usb serial devices.
MODE=”660″, GROUP=”dialout”

################# end ##################

create shell script into /usr/local/bin/go_u.sh
as below..

#################### start
#! /bin/sh

if [ $# -lt 2 ] ; then
echo “go_u “
exit
fi

echo port $1
echo speed $2
echo apn $3

/usr/sbin/pppd /dev/$1 $2 nodetach debug crtscts linkname “$1.link” connect “chat -v ECHO OFF TIMEOUT 15 ” AT OK ‘AT+CGDCONT=1,\”IP\”,\”$3\”‘ OK ATE0V1 OK ATDT*99# CONNECT” novj asyncmap 0 lcp-echo-interval 20 lcp-echo-failure 3 usepeerdns defaultroute

######### end

to connect

just need to type.

/usr/local/bin/go_u.sh ttyUSB0 115200 my3g

or you may alias this command to another shorter form..

such as.

touch /usr/local/bin/my3g

vi /usr/local/bin/my3g

##
#!/bin/sh

/usr/local/bin/go_u.sh ttyUSB0 115200 my3g &
exit 0

  • bro,
    i have zero knowledge on programming..could you pls explain in plain english..
    im trying to figure out how to use my umobile modem with digi simcard...

  • interesting.. may be u can check the DNS server setting. if centos 5 somewhere in /etc/resolve.conf
    sometime it did'nt automatically updated or not effective at all.

    else just append this to that file.or whatever file that set the DNS server thingy.
    these i think for digi primary and secondary dns server.

    nameserver 203.92.128.131
    nameserver 203.92.128.132

  • sorry...getting frustrated and sleep last night. still cant received any data..i also dun know what happen

    if i used umobile, the transfer rate is vary...between 0 to 150 kbps..sometimes more. but what frustrate me is it is not maintain. for example, if i want to watch live streaming, it didnt maintain for 150kpbs..but ranging from 0 to 150..thats y i try to use edge which have a clear signal at my house. my pda mean while only support gprs.

    another example, if i download mp3, gprs transfer rate is around 4-5 kbps but using umobile i only get maximum 2kbps which is unbelievable given that umobile is UMTS.

  • by the way .. i'd terminated the 3G. get back to wired broadband.. hehe.. so far not that much trouble at all.
    can view the youtube stream quite fast..

    but I maybe not that net speed hungry user.. 8-)
