I was using a Huawei E169 data card to connect to the Internet with my portable computer (OS Windows XP). I did change it to Mac a few weeks ago, and I can't connect to the Internet. Can I download a patch to use the data card with my Mac?
You cannot use the same software to connect your Mac to the Internet as you used to connect your PC. You should download and install the following software on your Mac. After this, you should be able to connect to the Internet with no problems.
