I came across more than once not being able to access a router (for the first time use) via a browser. It replays to a ping.
It seemed to be a trust issue. In a previous case I access the router with a older OS and browser ignored the warning about unsafe site, after getting in to the router I updated the firmware, then I was able to access it even with windows 10 still is warning about insecure but at least have the option to continue.
Is there a lass secure browser or any other way I could get access to the router (tried chrome Firefox IE)?
