ok i have one more solution, this should work, press the reset button on your router which should probabaly be at the bottom, then disconnect your router from the 'modem', then connect your router only to you pc via ethernet cable , then enter 192.168.1.1 or 192.168.0.1 over on the firefox once the router is up and running, if the login screen appears, good the next step ill tell you if the above works, if this doesnt work ur router is messed up then
