Weird Problem: Can't Connect to wifi with one laptop

I have an odd problem I've never encountered before. My wife's laptop will not connect to our wireless network. It connected once for a few minutes now it keeps saying the security key is no good, but I'm sure I am typing it correctly.

• I tried forgetting the wireless connection
• I rebooted the router (multiple times)
• Tried release/renew the IPs
• I have other laptops, tablets that connect no problem

I'm stumped it's like it has the wrong security key saved somewhere in it? Any ideas? Anyone?

 

Have you tried to connect the wife's notebook with security turned off temporarily?

If it still has the issue then the problem is elsewhere.

Reset the router to factory settings and redo your password and WPA2 PSK(AES) setting.

 

have you tried disabling and reenabling the NIC? reinstall/update the driver maybe?

EDIT: totally skimmed over the security key bit. you can probably safely ignore this advice.

 

Go into the manage wireless networks area. Right click and go to properties and find the security area. Switch this to the same setting you have on your other laptop. You should be using WPA or WPA2 and TKIP or AES or Both. Try switching between those 3 options.

 

I would advise using both setting I know from my Netgear it says for full throughput was to choose AES and laptop with TKIP or vise versa I have to go home to double check but it did pop message saying doing that would give higher speeds rather then using both same time. If it says different I'll to correct it.

 

TKIP will not permit N or AC speeds.

Set the router to WPA2 PSK(AES)

This was OK in Windows 7 but not Windows 8.

Microsoft removed the ability to delete Wi-Fi networks from the network list if the network isn't in range. Manage Wireless Networks is also gone from the control panel. If you want to better manage Wi-Fi networks in Windows 8 and 8.1, you'll need to head to the command line.

To see stored wireless profiles, type:netsh wlan show profiles

To see the stored key (WPA/WEP/etc) of a specific profile:netsh wlan show profiles name=[profile name] key=clear

To delete a stored profile:netsh wlan delete profile name=[profile name]

This will delete the stored profile of every WLAN interface. If you want to delete the profile of a specific WLAN interface, you need to use the following:netsh wlan delete profile name=[profile name] interface=[interface name]

To set network priority use this command:netsh wlan set profileorder name="network_name" interface='interface_name' priority=1
