Thank you very much for your well-informed observations.

Actually, the sequence of events was as follows: install stick and Mobile Partner and use them on WinXP computer 1 (all fine), then install and use them on WinXP computer 2 (all fine), then install and use the stick on Linux on computer 2 (all fine). Then, after I had finished my first (and only) successful session in Linux, I went back to WinXP1, and found I had no Internet access there, then back to WinXP2, again with no access there, and then back into Linux, and again found the same, that the line to the Internet was dead.

After I spent the weekend trying to troubleshoot this problem, I exchanged the stick, installed the new one on WinXP1 and had the same good internet connectivity that I had all the way at the beginning with the first stick, and this has continued now for the past 4 days.

In Arch Linux, for Internet access through a 3G modem, I followed their recommendation to use Gnome networkmanager. That seems to be the easiest way to set up and manage this connection. After I'd installed that package as well as a bunch of other packages (nm-applet, modemmanager, usb_modeswitch, xplc, wvstreams, wvdial, and mobile-broadband-provider-info), I found that setting up the connection through the modem was plug-and-play, no problem at all.

Strange then that after that, when I relied again on the previously successful automatic settings established by Mobile Partner in Windows and networkmanager in Linux, which presumably hadn't changed at all, I failed to get an Internet connection. If this situation recurs, should I go into Linux again now, I would have to troubleshoot it without access to the Internet, not an easy matter.

I may give it a try, and also try out other G3 network configuration and managing programs such as Sakis3G in Linux and MWconn in Windows, or bite the bullet and go into the guts of networking and configure everything by hand, should the problem recur.

I didn't have any other active network connections when I plugged the stick back into the Windows systems or the Linux system, at the time when connectivity failed. Also, I never got a working connection again in Linux either, with the first stick.
