I think I said above that when I try to login using the address and the login details as per the bottom of the router I get the error message 'this site cant be reached'.
So what is on the bottom of my router does not correspond to any log in details including the IP address.
I cannot log into it, if I do a reset I have no idea what it will reset too as it's not my router it's a supplied router.
I am not willing to try anything unless I can recover from it, I certainly don't have the skills or understanding, so I am going to ask my isp to change my password with one I will supply them with
