I am using Mac OS X SnowLeopard. My Huawei mobile broadband E173 data card is giving me problems. After inactivity for some time, it gets disconnected and when I connect again, it shows as connected but sites don't get loaded. Even the default startup page that's supposed to start on connection is not able to load.

I am using the default driver that came with the device. Are there any alternative drivers?

I had a similar device. I will just post some insights I got using that.

Mostly I remember it didn't work when it wasn't plugged in at boot time. But I remember also similar problems as you describe.

Could you check next time it occurs to you quickly reboot and see if the problem persits?

Actually after some trying I found out that I could not only connect through the Huawei software, but also through the built in modem program of Mac OS. In the Network settings the modem showed up and I could connect from there - even automatically. This turned out less prone to problems. (How do you connect?)

Also I remember it was not easy finding current drivers (my provider didn't have any for Mac). In the end I ended up downloading the most current from another network provider and manually inputing the correct settings.

It's a problem with your network. Try another SIM provider.

Do you have any info (website etc) that would support this theory? – myhd Nov 8 '12 at 11:50
