Reset network, can log in, even as Admin, BUT???

I can log in after the reset, as myself and as Admin BUT when I login as Admin it then requires me to change the password.
I do with very strong passwords and it gives errors that it can not change the password and kicks me back out.
I have tried over 10 times with no luck.
It is also interesting that the Qfinder shows the last pair of the MAC address as not the same as it is. It is off by 1 digit?
