So I picked up an R6400v2 second hand. First thing I did was a factory reset via the recessed 'reset' button for 7 seconds. When I try to access the settings page via IP, routerlogin.net, or routerlogin.com, it takes me to a blank page. I've tried edge and chrome, with clearing history, connecting via wifi and ethernet, and tried connecting on my android phone and using chrome there. To rule out subnet issues, I've tried connecting with the router not connected to anything else, including my modem. I can't see any reason I shouldn't be able to access router settings with no internet. The nighthawk app will connect, but keeps insisting there's not internet, even when plugged into my modem. My modem is a modem only, no router features included. I have cable internet and went and bought my own modem so I didn't have to rely on a gateway from my ISP. As I cannot get anything to load when trying to connect, I haven't the slightest idea what firmware I'm running.
Hoping I'm just missing something blindingly obvious and didn't purchase a dud.
