I need to know the version and hardware model of routers i am connected to. I dont have login permissions into all this routers but i can ping all of them.
Is it possible to get this information without login into the router?

yes there is but I don't know you and what your asking could be helping you hack into something your not allowed to. Please understand I'm not saying you are a hacker or upo to anything illegal but any reputable website like this would not and should not answer these type of questions
