buffalo router

[jgk1938]

I have a Buffalo-G-FB4, WHR-300HP2D router.  I've had it for about a month.  Recently the wireless stopped working.  I tried to connect to it and I'm asked for a Network Security Key.  I don't know what this is.  It worked just fine before.  Now it only works in Ethernet cable mode.  Can you help?Joe

 If you forget your router password then reset it to the company's default. After reset you will be able to access the internet again through Wi-Fi. I hope this one help you to resolve your problem.
