Hi, from your data everything seems to be OK.
Try to untick "work offline" in Firefox Menu:
File > Work Offline (ALT-F W)

i have the zte mf622 modem which i tried and got it working. for some reason it didnt work under the preset "3" option it always was trying through the "cdma" option with dial num #777 so i just right clicked the wireless icon (top panel) > edit connections > mobile broadband > click on auto mobile (CDMA) connection > edit > tick connect automatically .and in number type *99# exit and right click wireless icon again and untick wireless (restart or logout may be required) and try to connect oh and keep "enable networking" ticked on

Just a suggestion because I had a similary problem with the MF636 usb modem from Rogers :
verify that your /etc/resolv.conf have read permissions for all. If you don't understand this point, just run in a shell :
chmod 644 /etc/resolv.conf

As GeorgeVita said, you are well-connected on Rogers Network.

Hi, any chance you could point me towards step by step directions for installing and using my Rogers stick? All of the instructions I have found so far are for other models and don't seem to work!

Cheers,

Hi CArrowsm,
I have a ZTE MF636 and using it on Ubuntu 8.04. The main problem with theese modems is that respond to the system by default as CD drive or USB hub (19d2:2000 on lsusb command) but we need the actual modem which selected after issuing a special AT command AT+ZCDRUN=8 (then it responds 19d2:0031).

Note that above numbers are the Manufacturer and the Product Identification number which is shown when you execute the command lsusb from a terminal window.

At first try the lsusb command and copy paste the results to follow up. Also read my post#2 at http://ubuntuforums.org/showthread.php?t=1005910

I have JUST installed an Ubuntu 8.10 from an alternative installation CD (ISO i386) to my Toshiba Satellite L30-113. I did some modifications found on various posts (most in ubuntuforums.org) and I am connected with my ZTE MF636 3g modem via Network Manager 0.7 (I have already downloaded over 250MB of updates before posting this note!).

Below are the steps you may follow to work with your ZTE MF636:

1. Boot without the MF636, wait for the system to stabilize, open a terminal window, plug in the modem, wait 10-15 seconds and run the command: lsusb

If among the responds you see 19d2:0031 go to step 3.

2. The modem responds 19d2:2000 (as the internal CD drive or USB hub) but we need the actual modem (19d2:0031). You may use a special program called usb_modeswitch (see http://ubuntuforums.org/showthread.php?t=1017630) but I preferred to send the AT command AT+ZCDRUN=8 from a Windows PC to the modem (use hyperterminal or add it as an extra init command through control panel).
This command turns off the AUTO RUN function of the internal CD, if you want to return to default you have to send AT+ZCDRUN=9 (info taken from www.matt-barrett.com).

Test again the terminal command lsusb to be sure you have 19d2:0031

3. Make a new "rule" for MF636 to create the usbserial communication port (/dev/ttyUSBx).
From terminal run: sudo gedit /etc/udev/rules.d/90-zte.rules
copy paste the following lines (according to post#4 of http://ubuntuforums.org/showthread.php?t=665332):

ACTION!="add", GOTO="ZTE_End"
#
SUBSYSTEM=="usb", SYSFS{idProduct}=="0031",
SYSFS{idVendor}=="19d2", GOTO="ZTE_Modem"
#
LABEL="ZTE_Modem"
RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x0031",
MODE="660", GROUP="dialout"
#
LABEL="ZTE_End"

Save and Exit from gedit.

4. Edit HAL info to see MF636 instead of MF628. From a terminal window:
sudo gedit /usr/share/hal/fdi/information/10freedesktop/10-modem.fdi
Search (ctrl-F) for 19d2, go to line after "<!-- ZTE MF628 HSDPA USB dongle -->" and change usb.product_id from 0015 to 0031
Save and exit from gedit.
NOTE: this edit must be done again if an Ubuntu update restores the file 10-modem.fdi to defaults!

5. Remove modem from USB port, reboot, wait for the system to stabilize, plug in the modem. After a while a message will appear over the Network Manager icon (2 PC screens up right) and help you create a Mobile Broadband connection. After created click to Network Manager icon, and click to your provider.

Some debugging notes:
- If at step 5 the "message" not appears, try to make the setup manually (right click on icon and "Edit Connections")
- From terminal the command ls /dev/ttyU* will show you the usbserial ports for the modem. There must be four (4) up to /dev/ttyUSB3 which is our modem. If you boot with the modem attached you may have up to /dev/ttyUSB2 and this needs extra modification to the 10-modem.fdi file (the parameter usb.interface.number" int="3" must be changed to2).

Post any question to test it and follow up.

Regards,
George

Hi again,

After running lsusb this is the output:

Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 19d2:2000
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


Now what? I still can't get my computer to recognize it at all even after following all the instructions I can find!

Arrrgh.
