Sometimes routers can get messed up and need to be reset to fix the routing. I suggest trying to power off your modem and router, then power your modem on and then power your router on once the modem gets a good signal. If that doesn't work, then try setting your router back to factory defaults and setting it up again. I know sometimes Linksys' can flake out of you have a few ports forwarded in it for a while, and especially so if you have a lot of ports forwarded.
I just added a section to the FAQ in the wiki for this type of issue:
