I know how to reset these to factory defaults, problem is I don't want to do that because there is so much info in there that is not easily accessible. For on the IT guy before me changed it and he says that he gave it to me but what he gave me does not work. I would have to call my ISP and wait forever to get all my IP info, since the last guy never wrote this stuff down. We have many port forwarding options and dont want to miss one.
So, other than setting back to defaults, how can I hack/brute-force..etc into this thing???
