I have the same router, different problems. The wireless connection on it has been flaky since day one. It drops the connection at random intervals. Sometimes it comes back, sometimes not. The wired ports don't seem to be affected. I've tried moving it, upgrading the firmware (twice), resetting it to factory defaults, and punching it in the face. Finally last Tuesday I called Linksys to get an RMA, which was an extremely annoying process requiring too many fucking phone calls. I selected three-day FedEx shipping and its six days later and I do not have the replacement router. Fuck linksys up their stupid asses.
