    Hello all. New to the forum and have a question that hopefully someone can help with.

    I bought the Acer laptop for my mother at Christmas. Vista Home Premium is the OS. She recently signed on with AT&T for internet service and they sent her the new USB 881 adapter. We plug it in, it downloads the AT&T Communication Manager, restarts, then the screen goes black. After getting it to reboot and double-clicking the ACM, it will not initialize the adapter. An error will then come up in the taskbar stating the USB device is not recognized by Windows. She spent 8 hours on Friday with AT&T support with no resolution. She also went to their office.

    I'm not sure what all they did, but I went to her house today to see what I could do and the wireless mouse would not work any more either. Performed the eRecovery, tried everything over again and have the mouse working but have the same problem with the adapter.

    Can any one offer any solution or advice?

    Sounds like it's not Vista approved. Or your firewall is blocking it.

    Someone on the AT&T forum suggested installing the 3G Watcher software instead of the ACM and to install it before plugging in the card. I performed another eRecovery, installed the 3G Watcher Software and drivers first, plugged in the card and it still said "no device" detected". I went to the Sierra site and it said to go into TRU-Install and change it from "software installation mode" to "modem mode". This worked!

    Problem is, I disconnected from the network using 3G Watcher, unplugged the card, reopened 3G Watcher, plugged card in and again got "no device" detected". Opened TRU-Install and it was back into "software installation mode". Is there a way to lock it into "modem mode"?
