Hi, i'am trying to write a program to test computers on my lan and i trying to test to see if i can try the default username and password to logon to a broadband and wireless router.

What i've got so far is
Connect to router(
connect to port(80)
GET / HTTP/1.1

Then would i do something like
PUT .......
to enter the user and pass .
And how would I know if its succeded, would i have recive, and see if it returns the homepage.

I've tryed to look at the data with wireshark and etthercap but i didn't find the command to add the user and pass.

Thanks in advanced
