Interesting. I also have many Netgear products and just tried a few of them. They all use the same method... basically, it is in the configuration of Gateway. You aren't going to be able to simply "upload" a new file to the gateway is what I'm trying to say. You are probably going to have to tunnel through to the gateway using some sort of custom application. I'll look more tonight but thats a guarantee at least with my model numbers (DGL Series)
