Hello,

I tried log into C58HP administration page after opening http://tplinkwifi.net/

It asks for a password and I entered the right password. (Please note that I created this password using Tether mobile application)

But, even after typing in the correct password, I could not login. The page just stays as it is and does not open the administration pages.

I tried to see what is happening behind the scenes by opening "Network" tab in "Chrome Developer Tools" debugger.

Here is what I saw when I clicked on Login button after entering the password:

Please help me log into my router. I'm unable to perform advanced configuration using Tether.

Thanks a lot in advance !
