I have the Linksys WAP55AG. All that is plugged into the device is the AC adapter. I pressed in and held the rest button for 15-30 seconds. The red Diag light came on for 2-3 seconds and disappeared. The ACT lights for both the 54g and the 802.11a began blinking and the Link lights both became solid green. What the hell? Is the device bad? Help!
