Change router password

[SimonJake]

Hi i want to change my router password and i have followed all the steps but when i go on to the summary status page and click

wifi to get to the next step i get the message 401 unauthorised, authorisation required.

This happens on all the options on that page apart from reboot sky hub, can anyone help, thanks.

I have tried it on desk top pc and also on my mobile through the app and its just the same.

A message also appears at the top in the brower bar when i get to the summary status page that says not secure do not change any passwords on this site.

So i have managed to get in through google chrome but above the username / password box it says your connection to this site is not private, is this right ????
