Sierra's website says this device is compatible with Linux.
I did an install of Ubuntu 10.04 recently, and initially the Sierra USB
thingy was working fine, but then it stopped. Fiddled around a little and I
eventually got it to work again (I'm not sure that anything I did was
actually responsible for this) but apparently it stopped working again
shortly after I left.
A few weeks later I upgraded all the packages, something I hadn't done
during the install, and the device started working again. I rebooted the
machine several times and each time the connection came up reliably soon
after I connected the device.
Now it's not working again. It's not working on my Debian machine either.
But it works perfectly in any windows machine every single time, and I've
carefully checked the APN, authentication and compression settings and made
them the same under Linux (PAP only, no compression anywhere) but still no
worky.
Any suggestions?
