Try this, if only temporarily to see if it connects, log into your SpeedStream 4200 & disable NAT .. or/& set for DMZ. See if LW connects then. If yes, then you will need to port forward the device so you still have NAT security but a rule allowing LW access. It would suggest that model's UPnP doesn't work efficiently for everyone.

There appears to be a lot of users using the Windstream service & having problems connecting with LW. Do a forum search for Windstream & you will get an idea.
