I'am having exactly the same problem. My laptop was connecting fine this morning and all of a sudden the wireless network is dead. My desktop which is hardwired to the router works fine. But the laptop can't even detect the router. The only thing I haven't done is do a complete reset of my router. I have D-Link router WBR-1310 and all this has given me is trouble since I got it a year ago. I am fixing to go buy me another Netgear cause the first one I had never gave me any problems, but a power surge burned it and bought this thing because the sales person highly recommend it. One thing I did notice is that another D-Link router popped up in my area and it's open. Could there be interference? I know my laptop adapter is working fine because I test it with this open line. Any other suggestions before resetting and starting from scratch?
