After installing Lion, my usb broadband modem doesn't work
I have Xfinity Internet 2Go with a Franklin Wireless CMU-301 usb 4g/3g dual mode broadband modem. It worked great in Snow Leopard. I don't have WiFi access at my job. I need to access the Internet, so I use the usb modem. After I upgraded to Lion and got to work, I found that the usb modem doesn't work anymore. I have had to tether my iPhone to get on the Internet tonight, and I just can't afford that. I tried uninstalling the connection manager from Xfinity and reinstalling several times, but nothing I've tried works. I know both usb ports are working, because they have both charged my iPhone just fine. The connection manager insists that it can't find the usb modem, even though it lights up. I tried resetting the SMC. No, I don't have Avast or any other antivirus software.
If I can't get on the Internet, I will have to downgrade back to Snow Leopard (because there is really no point in even having a computer if I can't get online), and that sounds like a giant PITA (plus I don't know how). I would lose any software I downloaded from the Internet, wouldn't I? I'm really angry with Apple! Don't they know that many people need to use usb modems to get online? Why wouldn't they make sure they would still work, or at least warn us that they wouldn't work?! I'm really, really ticked off! What a waste of $30!
