have you tried adjusting your router settings. by accessing them via your pc or a physical cable connection by entering 192.168.1.1
this will bring up all your settings.
it should ask you for a passwords and username by default its usually admin admin or something along those lines.
i would strongly advise against trying to edit router settings however if your unsure of what your doing.
because then you could be internet-less LOL..
thennn theres no way to find out anything...
sounds silly but start with basics try removing the power lead from your router and keep it off for 10seconds, as routers.. well CISCO routers havea 10 seoncd memory as do most electronics with RAM memory.
so just count to 15 or someting to b safe..
if you give me a bit more info in to what its actually doing and saying i may be able to help
