Does the page say 'Your Test Worked' ?

Possible issue I see off-hand is the Linksys router.

Have you ever been able to connect with LW or uTorrent with your present computer set up?

Yes I have been able to use LW with the current setups!

It doesn't say your test worked...

So, do you have any idea?
