Hi mskate. May I suggest your forward a port on your Netgear router to allow LW access. You will 1st need to set up a Static IP for this work. (By the way your model is MR814, not RM814. Netgear don't have any such model.) I have 2 sets of instructions. 1.
Static IP & Port Forward for MR 814 & 2.
Forwarding a port on MR814 And use
Port 6346 or you could do the range
6346 to 6348.
Once you have succeeded doing this, try to connect to LW. Give it some time. If you're still having problem, go to LW's Tools>Options>Advanced>Firewalls & select UPnP & press Apply button. Try again.
If it still fails. Within LW, go to Tools>Options>Advanced>Firewalls & select Manual Port Forward. See
Force IP instructions & sample image & following post.
* Make sure you have configured all your firewalls to allow LW's access (including XP Firewall):
