D-link DI624

Hey guys my dad has a Dell inspiron with internet built in so it detets the internet connection near it and it picked up our nextdoor neighbors connection and i found that they have a D-link DI624 and i wanted to play CS:s but steams port seams to be closed so i wanted to open it so i went to 192.168.0.1 and etered the username admin and the password is suppose to be blank but when i did it it didnt do anything

is the password wrong or is it that they are blocking me from changing the settings and i cant be like walking over there and being like

" Hi im stealing u connection and id like u to open some ports on ur router for me so i can play some games "

so if u guys could give me some help id be greatful thanks!

nevermind the problem was resolved

it was the macafee firewall so i allowed steam and CSS and hl2
