n300 wnr2000v5 wifi router firmware latest version

Actually, I do have an issue; but because my firmware question was answered I moved on. However, the additional problem I had was and still is that I cant log into my Admin account/ Genie or whatever that window is called. Before now, I could log into that account( Admin) by using routerlogin.net; but lately even though I use that URL, it only allows me to login with my email address/username. It does not give me the Admin login window at all. So I'm unable to access my router info or make any Advance changes I want to. 

Any recommendations would be appreciated.

 

Thanks
