<div>I kind of never expected to have another question for this list. I'm not
even sure it's still operational. But I guess we'll see.</div>
<div> </div>
<div>We have two AS5400's providing dialup services, one in Kentucky, and one
across the river in Indiana. The one in Kentucky has no problems at
all.<br><br>Recently, a user in Indiana switched to Windows 10, and found that
her dialup connection there no longer worked. She gets connected and logged in,
but then gets 80-90% packet loss. She still has her Windows 8 computer, and that
still works fine with her dialup connection. We went over with a windows 10
unit, a windows 7 unit, and a linux box, and tried dialup up with all three. The
windows 7 and linux boxed worked fine, the windows 10 unit had the same problem
she did.<br><br>We then tried calling another user in Indiana whom we thought
had switched to Windows 10 a while ago. Turns out, he told us, that his dialup
connection never worked with Windows 10, so he switched back to Windows
8.5.</div>
<div> </div>
<div>Our memory is that a year ago we were helping a partner in Canada who had
some dialup services with an AS5400, and he found that Windows 10 users didn't
work for him with it, but he just figured it was something with Windows 10 and
didn't worry about it.<br><br>Like I said, Windows 10 works fine with the AS5400
in Kentucky, so I tried isolating differences between those boxes, to the point
of making them identical with IOS, modem setup strings, modem firmware, etc. No
difference. In fact, it made things worse. Many people were failing to connect,
including the woman with the initial problem. Now the Indiana box is back to the
way it was, and just that woman who is trying to use Windows 10 has her problem
of getting connected then being unable to do anything.<br><br>Here is the box in
Indiana.<br><br></div>
