maybe iamelmo1 wlan card does not support the security settings on the router. Try change the WPA2 to WPA, WPA2-tkip to WPA2-AES, or to WEP (BUT just for the test, cause WEP is not secure AT ALL) and change the channel your wifi is in. It may be on a very populated channel.
The suggesting about the fisical wifi on/off is valid but not on his case because he said on the 3rd post that he cannot connect, he does not state that it cannot see wifi networks, only that is keeps failing to connect.
You can also try to boot on live operating system like mini windows xp on the "hirens boot cd 15" or a linux live cd, written on a usb thumb drive, and see if it connects to the wifi.
Other than that, it may be your wifi card damaged. If its the case, try to get an exact make and model of your wifi card because most probably the bios on your laptop as "whitelist" for the devices it accepts and it wont boot with an "unauthorised" wifi card.
wishing the best of luck on your venture to find the culprit, iamelmo1.
And the best for the supporters on this amazing forum! Thanks
