Wow you're a step ahead of me. lol
I forgot to tell you how to force IP within LW. If you haven't already see this:
Force IP instructions for LW You NEED to do this. Actually I can't find any info on how to port forward your specific model of modem. You couldn't tell me could you. It would be very beneficial for other users. There's 2 others with connection probs just this week who have the same model as you.
It sounds strange LW should take 10 mins to load up properly & the blank screen doesn't sound healthy to me. If you continue having this issue then please post back & we'll see if we can sort it out.
