So I've been reading about all the problems that everyone's been having with the Port Forwarding, and noticing I had the same story. Started around November-ish, and still continuing on. I've tried the multiple ways of fixing it, but I still cannot delete/edit ports on my router, as it's been reported. I don't even have the model that has been said to have this problem, but it still does it to me. Also, I have no idea what 'Power Cycling' means, so if anyone could define that, that'd be nice, too. Thanks.
