I have had this problem a few times before and it seems to happen about every 5 or 6 months. All of a sudden none of my wireless devices will connect to the router. In order to fix it, I have to go in and change the SSID to something else and then I can connect fine. No other settings are changed in the router. Usually after a few days, I can change the SSID back to what it was originally and it works again. I'm baffled as to why it's doing this and would like to figure it out. Am I missing some setting somewhere, or is there a way to fix the problem without changing the SSID? I am using the latest "tomato-E4200USB-NVRAM60K-1.28.0500.5MIPSR2-Toastman-RT-N-VPN-NOCAT" firmware right now, but this has happened on previous versions too.
