I'm posting this for the other poor souls who've purchase a Rogers ZTE MF668 HSPA Rocket Mobile Internet Stick and can't get it to connect using Snow Leopard. 1. Attach the stick to the computer. It should appear as a mounted volume. Run the Connection Manager install program to install the drivers. If you can't see this they may already be installed but you can download and install from Rogers the ZTE MF668 MAC OS 10.4 Software.
2. After the install, go into System Preferences > Network. Unplug and plug back in the stick to ensure the device is identified properly. Two devices should appear, ZTEUSBModem and ZTEUSBATPort. Follow the next to steps for each. (Note: the Rocket Stick should have a red light that turns blue when successfully on the network.)
3. Select the device and enter wapuser1 for the Account Name and wap for the Password
4. Click the Advanced... button and in the Modem tab that appears select Generic for the Vendor and GPRS (GSM/3G) for the Model. Enter internet.com for the APN and leave CID at 1. Click OK to finalize the Modem settings.
5. Click the Apply button to apply these settings and repeat steps 3 and 4 for the second device.
6. Select the ZTEUSBModem and click the Connect button to test. If all goes well you should be connected within 15 seconds.
7. Disconnect and exit System Preferences and use the Connection Manager to test the connection again. You can connect using either but the connection manager is slightly easier to open and connect with especially if the end user isn't that technical.
