Comfast AX3000

HI There

I bought a Comcast AX3000 router and connected it all up using the default password "admin". When I came back today and tried to connect it won't let me. The password is now different as it is requiring 8 characters not the original 5. Also the http://mwlogin.net that they direct you towards does not work. Any help appreciated.

I might be wrong, but it appears that this isn't an GL.iNet device?

Sorry I didn't realise this was make specific!
