I'm using PLDT WeROAM and been using it for about 2 months now. I've
managed to connect it using wvdial/ppp. Earlier tried to use comgt
and make it work but with intermittent connection. You need to use usb_modeswitch
to switch the device from storage to modem mode. Here's the howto: Test Machine: OS: OpenSuSE 11 32-bit usb_modeswitch --> http://www.draisberghof.de/usb_modeswitch/ Check the list of supported devices. libusb, wvdial --> prerequisite packages to control your 3G/GPRS cards. Test Device: ZTE MF620 HSDPA data card. Note: Unplug your device until the configuration is ready. 1.Install the usb_modeswitch #> tar jxvf usb_modeswitch-0.9.4.tar.bz2 #> cd usb_modeswitch-0.9.4 #> ./compile.sh #> cp usb_modeswitch /sbin or #> cp usb_modeswitch /usr/sbin 2. Copy the usb_modeswitch.conf to /etc. You can also use the updated version found in http://www.draisberghof.de/usb_modeswitch/. 3. For ZTE MF620, comment out the designated configuration for the said device, or enter the following at the bottom of the file: DefaultVendor= 0x19d2 DefaultProduct= 0x2000 TargetVendor= 0x19d2 TargetProduct= 0x0001 MessageEndpoint=0x04 MessageContent="55534243123456780000000000000600000000000000000000000000000000" 4. Create a new udev rule for ZTE MF620 device. Save it as /etc/udev/rules.d/15-zte-mf620.rules ACTION!="add", GOTO="ZTE_End" SUBSYSTEM=="usb", SYSFS{idProduct}=="2000", SYSFS{idVendor}=="19d2", GOTO="ZTE_ZeroCD" SUBSYSTEM=="usb", SYSFS{idProduct}=="0001", SYSFS{idVendor}=="19d2", GOTO="ZTE_Modem" LABEL="ZTE_ZeroCD" #RUN+="/sbin/rmmod usb_storage" LABEL="ZTE_Modem" RUN+="/sbin/usb_modeswitch -d 1 -v 0x19d2 -p 0x2000 -V 0x19d2 -P 0x0001" RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0001", MODE="660", GROUP="dialout" MODE="660", GROUP="tty" LABEL="ZTE_End" 5. Edit the /etc/ppp/peers/wvdial file. Add / modify it with the following: usepeerdns plugin passwordfd.so noauth name wvdial defaultroute replacedefaultroute noipdefault novj nobsdcomp 6. I haven't fixed my /etc/ppp/option.. try removing redundant entries, but here what I currently configured. noipdefault refuse-chap debug kdebug 7 noauth modem crtscts lock asyncmap 0 #usepeerdns #replacedefaultroute #defaulroute lcp-echo-interval 30 lcp-echo-failure 0 lcp-max-configure 60 lcp-restart 8 ipcp-accept-local ipcp-accept-remote ipcp-no-address ipcp-no-addresses ipcp-max-configure 50 ipcp-restart 8 idle 6000 noipx novj mtu 1456 file /etc/ppp/filters 7. Then modify your /etc/wvdial.conf with entry similar to this: [Dialer Defaults] Phone = *99***2# Username = YOURUSERNAME Password = YOURPASSWORD APN = ACCESS POINT NAME OF YOUR NETWORK Stupid Mode = 1 [Dialer weroam] Modem = /dev/ttyUSB0 Baud = 921600 Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 Init3 = AT+CFUN=1;+CGDCONT=2,"IP","weroam" Area Code = Ask Password = 0 Dial Command = ATD FlowControl=NOFLOW Stupid Mode = 1 Compuserve = 0 Force Address = Idle Seconds = 3000 DialMessage1 = DialMessage2 = ISDN = 0 Auto DNS = 1 8. Now plug the usb device and wait around 1-2 minutes to establish device detection. you can verify it via tail -f /var/log/messages and wait for the message similar below to appear: Jun 12 16:19:26 linux kernel: usb 1-1: generic converter now attached to ttyUSB0 Jun 12 16:19:26 linux kernel: usbserial_generic 1-1:1.1: generic converter detected Jun 12 16:19:26 linux kernel: usb 1-1: generic converter now attached to ttyUSB1 Jun 12 16:19:26 linux kernel: usbserial_generic 1-1:1.2: generic converter detected Jun 12 16:19:26 linux kernel: usb 1-1: generic converter now attached to ttyUSB2 9. Then execute wvdial weroam Note: Check the following configuration in /etc/wvdial.conf Baud = 921600 ## This is the highest setup you can also use 460800 or 384600 Phone = *99***2# ## By default normal 3G connection in the philippines uses *99# Init3 = AT+CFUN=1;+CGDCONT=2,"IP","weroam" ## when using *99# on phone option change the +CGDCONT=2 to +CGDCONT=1 On 08/08/2008 06:49 PM, bryan wrote:
