Comment 4 for bug 360905

I too have the same problem with a Sierra Wireless AC875 (PCMCIA) on a Lenovo T61. However, in my case running through the wizard does not allow the device to be seen to network manager. Worked on 8.10 out-of-the-box.

The kernel still recognizes it when plugged in, but I could not get wvdial or UTMSmon to work (so it is not the same as this bug: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/368457 - where the device shows up in NM but does not connect). On the exact same laptop, if I boot into Fedora 10 (which has Network Mangager 0.7.0.99) it works out-of-the-box as well (9.10 uses NM 0.7.0.100)

The following is the output from syslog, I don't know how to get the console information from Network Manager. Let me know if there's any other information I can provide, this is a big show stopping regression for me, I'd rather not revert to 8.10.
