I just changed from dial up to broadband.
I also just changed from LWBasic to LWPro ver 4.16.6
I, too, have a Westell 327W wireless modem/router.
OS is Windows XP Pro, SP2
.... and, of course, am having identical problems as
in this post. After removing LW Basic software in my
control panel, and installing LW Pro, the software loads,
and as it connects, only the first of 5 bars turns green,
and the icon of the firewall remains.... then the software
just sits there forever.

Now I'm no computer techie, so all I can tell you at this point
is that the darn thing don't work. I haven't tried anything yet
to get it to work, only checking this forum for answers. But,
my first impression is that this is definitely a common problem
and perhaps someone in the know would be kind enough to
post a step-by-step list of everything to check in order to get
it working properly, and/or how to do it in novice terms. It may
just save a lot of postings in the future and help us all out.

Thanks so much if you are able to, and do such a thing.
The rest of us would certainly appreciate your invaluable knowledge.
